Messeveranstalter Reed Exhibitions erwartet rund 850 Aussteller dieses Jahr, das wären rund ein Viertel Firmen mehr als 2006, die sich dem internationalen Fachpublikum präsentieren. Auch die Besucherzahlen werden noch einmal kräftig zulegen: Mehr als 17.000 Fachbesucher aus allen Teilen der Welt werden nach Essen anreisen. Die ALUMINIUM 2008 hat sich damit zum globalen Event und zur wichtigsten internationalen Fachmesse der Branche entwickelt. Aluminiumunternehmen aus allen Produktions- und Wertschöpfungsstufen und ihre Technologiepartner werden sich und ihr Leistungsprogramm präsentieren. Die Spannbreite reicht von den großen Weltkonzernen bis zu mittleren und kleinen Aluminiumverarbeitern, die, wenngleich nicht derart umsatzträchtig, so doch in ihrem Produktsegment „state-ofthe-art“ sind. Die ALUMINIUM 2008 findet in einem insgesamt wirtschaftlich gesunden Branchenumfeld statt. Davon zeugen auch die Zahlen und Ausblicke, die der GDA Gesamtverband der Aluminiumindustrie jüngst für 2008 für die deutsche Branche präsentierte. Die Auftragseingänge sind demzufolge zwar leicht rückgängig, aber nach wie vor auf sehr hohem Niveau. Die Kapazitäten sind gut ausgelastet, die Ablieferungen in den ersten fünf Monaten haben sogar noch einmal leicht zugenommen. Ein ähnlich positives Bild ergibt sich aus einer Umfrage, die der wgm bei den Mitgliedern des Halbzeughandels durchgeführt hat. Noch einmal kurz zurück zur bevorstehenden Messe: Auch der Giesel Verlag wird sich mit seinen Metalltiteln (angefangen bei der Zeitschrift, die der Leser in seinen Händen hält, über die offiziellen Messezeitungen Aluminium Praxis und APT News bis hin zu den Publikationen APT Aluminium, Metall, Automotive Materials und Formwerk) auf der ALUMINIUM 2008 präsentieren – so viel Eigenwerbung sei gestattet. Only a few weeks before ALUMINIUM 2008 opens its doors, there are already signs that the fair will again be a complete success. Fair organiser Reed Exhibitions expects approximately 850 exhibitors this year, around a quarter more companies than in 2006, which will be presenting themselves to the international technical public. Visitor numbers will also be much larger: over 17,000 technical visitors from every part of the world will be travelling to Essen. So ALUMINIUM 2008 has developed to become a truly global event and the most important international trade fair for the branch. Aluminium companies involved in every production and value-addition step, and their technology partners, will be presenting themselves and their range of products and services. The scope extends from major world concerns to medium-sized and small aluminium processors which, although they may not have such large turnovers, still represent the state of the art in their product segment. ALUMINIUM 2008 is taking place in a generally economically healthy branch environment. This is also evidenced by the figures and perspectives issued by the GDA (Association of the aluminium producing and processing industry in Germany) recently presented for 2008. According to these, although there has been a slight downturn in order intakes, they still remain at a very high level. Capacities are being well used, and in the first five months deliveries were even slightly up. A similarly positive picture is given by a survey carried out by the wgm among its members in the semis trade. Returning briefly to the forthcoming fair, Giesel Verlag publishing house will also be presenting its metals industry titles at ALUMINIUM 2008: the journal you, the reader, now have in front of you, as well as the official trade show newspapers Aluminium Praxis and APT News, and the publications APT Aluminium, Metall, Automotive Materials and Formwerk – that much self-advertisement is surely allowed. 3 I N H A LT EDITORIAL ALUMINIUM 2008 wirft ihr Licht voraus .................................... 3 A KT U E L L E S Personen, Unternehmen, Märkte ............................................ 6 WIRTSCHAFT Englischsprachige Artikel: s. nebenstehendes Verzeichnis Aluminiumpreise ..............................................................

Klasse für Kurt Ehrke Kurt Ehrke, Vorstandsmitglied der Trimet Aluminium AG, Essen, ist mit dem Verdienstkreuz 1. Klasse des Verdienstordens der Bundesrepublik Deutschland ausgezeichnet worden. NRW-Wirtschaftsministerin Christa Thoben überreichte die Auszeichnung am 6. Juni 2008 im Düsseldorfer Wirtschaftsministerium (s. Foto). Bei Trimet ist Ehrke für Forschung und Entwicklung, Qualitätsmanagement, Produktion, Planung und Projekte zuständig. Außerdem vertritt er das Unternehmen in den Fachverbänden und im politischen Raum. Nach mehreren beruflichen Stationen in anderen Aluminiumunternehmen seit 1967 übernahm Ehrke 1994 als Generalbevollmächtigter die Leitung der Aluminium Essen GmbH, die aus der zur Schließung freigegebenen LMG Leichtmetallgesellschaft mbH der Alusuisse hervorgegangen und von Trimet erworben worden war. Ehrke stellte die gekündigten Mitarbeiter wieder ein und setzte sich für umfangreiche Investitionen ein. Die Hütte, die jahrelang ausschließlich Verluste geschrieben hatte, entwi- ckelte sich so zu einem erfolgreichen Unternehmen. Mit der Wiederinbetriebnahme der dritten Elektrolysehalle ab 1998 konnten weitere Mitarbeiter und Auszubildende eingestellt werden. Der offene Dialog zwischen Geschäftsführung, Belegschaft und Betriebsrat war Ehrke stets wichtig. 1999, Trimet 2001 und 2005, erhielt die Aluminium Essen GmbH bzw. Trimet für ihr soziales Engagement und ihre vorbildliche Beschäftigungspolitik das Arbeitsplatzsiegel „Arbeit Plus“ der Evangelischen Kirche in Deutschland. Ehrke trug wesentlich dazu bei, dass Trimet 2001 die von der Insolvenz bedrohten ehemaligen Metallwerke Harzgerode und Sömmerda erwarb. Er erarbeitete mit den Verantwortlichen vor Ort ein neues tragfähiges Konzept, mit dem die über 500 vorhandenen Arbeitsplätze erhalten werden konnten. Auch die Übernahme und die Wiederinbetriebnahme der stillgelegten Hamburger Aluminiumhütte hat er maßgeblich beeinflusst. Im Beirat des Essener Unternehmensverbandes e. V. übernahm Ehrke 2000 die Themenbereiche Energiepolitik, Beschäftigung und Ausbildung. Seitdem setzt er sich für den Wirtschaftsstandort Essen, für die Schaffung von Ausbildungsplätzen und für die Beschäftigung von Arbeitslosen, vor allem aus der Problemgruppe der Langzeitarbeitslosen, ein. Ehrke ist außerdem seit vielen Jahren im kirchlichen Bereich engagiert. 2001 wurde er in den Ausschuss „Kirchlicher Dienst in der Arbeitswelt“ des Stadtkirchenverbands Essen und 2002 in den Ingenieurrat des Bistums Essen berufen. Ihm gehören Personen an, die sich in fachlicher, sozialpolitischer, menschlicher und religiöser Weise besonders ausgezeichnet haben. N Kostenexplosion gefährdet die Aluminiumrecycling-Industrie Der Verband der Aluminiumrecycling-Industrie (VAR) schlägt Alarm: Eine Kostenexplosion bisher nicht bekannten Ausmaßes belaste die Branche und hier vor allem die Hersteller von Aluminiumguss- und -knetlegierungen. Von den Preiserhöhungen sind Legierungselemente wie Schmelzkosten gleichermaßen betroffen. So sind die Preise für Siliziummetall innerhalb von 12 Monaten um 60 Prozent, für Magnesium sogar um 132 Prozent gestiegen. Der Ölpreis hat sich in diesem Zeitraum praktisch verdoppelt, bei Gas und Strom werden spätestens im Herbst weitere Preissteigerungen erwartet. Außerdem werden wichtige Hilfsstoffe wie Schmelzsalze und deren Verwertung von der Preisexplo- 6 sion erfasst. Bei der Herstellung von recyceltem Aluminium liegen die Kostensteigerungen laut VAR mittlerweile bei 40 bis 50 Prozent, Tendenz weiter steigend. Wie Erich Oetinger, Vorsitzender des VAR, mitteilte, werde es für die deutsche Aluminiumrecycling-Industrie „langsam eng“, wenn es nicht gelänge, diese Preiserhöhungen in angemessener Form an die Kunden weiterzugeben. Knapp 80 Prozent der Aluminiumgusslegierungen in Deutschland (2007: 795.525 t) werden in der Automobilindustrie zur Herstellung von Zylinderköpfen, Motorblöcken, Getriebegehäusen und weiteren Anwendungen eingesetzt. Eine weitere Verschärfung der Kostensituation zeichnet sich mit höheren Transportkosten aufgrund gestiegener Preise für Dieselkraftstoff ab. Auch die Neustrukturierung der LKW-Maut wird kritisch beobachtet. Geradezu Existenz bedrohend ist nach Ansicht von Oetinger die Absicht der EU-Kommission, die im internationalen Wettbewerb stehende Aluminiumrecycling-Industrie dem Emissionshandel zu unterwerfen. Dieses Vorhaben erscheint auch aus ökologischer Sicht widersinnig, da die Herstellung von recyceltem Aluminium nur einen Bruchteil der Energie benötigt, die zur Produktion von Primärmetall erforderlich ist. Entsprechend vorteilhaft ist die Bilanz bei den CO2-Emissionen. Die Branche mit weiteren politischen Kosten zu belasten, würde die umweltpolitischen Ziele der Europäischen Union konterkarieren. N ALUMINIUM · 7-8/2008 NEWS IN BRIEF U. S. aluminium’s three ‘Cs’ sinking The three ‘Cs’ of the U. S. aluminium industry – cars, cans and construction – are facing a difficult second half and will experience only a measured recovery in 2009. Collectively, transportation, beverage cans and construction account for more than half of all the aluminium shipped in the United States, and conditions for all three are rather poor. In the automotive sector, which accounts for about 20% of all aluminium, shipped production is down about 10% year to date through May. U. S. vehicle sales fell 8.8% year to date, following a 2% decline in 2007. Car sales are expected to fall nearly 10% in 2008 followed by a small rebound in 2009. The one saving grace is that the car industry has slowly increased its use of aluminium over the past two decades. More aluminium is put into the average car. That trend continues. In 2007, the average car had 150 kg per vehicle, and that has been increasing at a 3 to 4% rate per year. That rate may pick up with manufacturers’ desire to lightweight. Shipments to the auto industry are down about 8% (in 2008) to 2.09m tonnes. For 2009 shipments are expected to be up about 6%. The news is not much better for the heavy truck industry. It was deeply depressed in 2007 with production down around 35%. Shipments of aluminium in heavy trucks were down 35% in 2007, and are expected to be down another 4.8% this year to 324,000 tonnes. The one bright spot in the transportation sector was aerospace, where shipments are forecast to grow about 10% in 2008 to 329,000 tonnes. Originally aluminium shipments (to all of the transportation sectors) were thought to be down 3% in 2008, but now it is looking like they will be down about 8%. Next year the market should rebound around 8 or 9%. Aluminum shipments this year will be around 3.22m tonnes to this market and next year that should climb to 3.49m tonnes. There is mixed news in the beverage can sector. Consumption of beer is up about 1%, while consumption of soda is down about 1%. But aluminium is slowly losing market share to glass bottles for beer and to plastic bottles for water and sports drinks. The can market will be up just over 3% in 2008, largely because the U. S. is able to export more cans in 2008 because of the lower dollar. 99.8 billion cans are expected to be made in the United States this year, which equates to about 2.09m tonnes of can sheet. For the construction sector the data are largely negative, including bloated inventories, few buyers and declining prices. Single-family home starts are down 37% to date and down nearly 60% from 2005. Meanwhile, non-residential construction spending is expected to slow 1.4% in 2008 and slip 1% in 2009, and many commercial projects will be vulnerable to delay and cancellations given escalating raw material prices, particularly for steel. Aluminium shipments to construction are forecast to be down 11.6% to 1.13m tonnes in 2008 and down 10% to 998,000 tonnes in 2009. N European Foundry Association New Secretary General elected Dust and its implementation. Furthermore, he serves as Secretary of CAEF Commission 2 (Environment). In his function as DGV counsel he was constantly involved in CAEF legal affairs, such as the General Terms of Contracting for European Foundries and antidumping proceedings. N CAEF who resigned after twelve years in this function. Mr Schumacher, a lawyer, has been working with the German Foundry Association DGV since 1993. Since 2000, he has been head of the Legal Department of the DGV.

He succeeds Klaus Urbat ALUMINIUM · 7-8/2008 7 AKTUELLES BMU-Fördergelder für Aufbereitung von Gießereisand Ohm & Häner Das Unternehmen, das seit 45 Jahren spezielle Gussteile für den Maschinen-, Anlagen- und Automobilbau herstellt, will im Rahmen eines Modellwechsel an einer Formanlage Gießerei-Neubaus ein innovatives Verfahren zur Trennung von Sandgemischen einführen, die bei der Produktion anfallen. Dabei werden die verschiedenen Sandqualitäten optisch-elektronisch anhand ihrer Farben identifiziert und pneumatisch getrennt. So kann die Altsandmenge von 8.400 Tonnen, die bislang teuer deponiert werden musste, jährlich um rund 75 Prozent auf 2.200 Tonnen reduziert werden. Ein innovativer Vakuum-Sandmischer wird den gereinigten Sand so aufbereiten, dass er problemlos in den Produktionskreislauf zurückgeführt werden kann. Dabei wird der Verbrauch von Bindemitteln und Wasser erheblich reduziert. Zudem können Lkw-Transporte im Umfang von rund 100.000 km entfallen. Im Rahmen der Gesamtinvestition am Standort Drolshagen sollen rund 150 neue Arbeitsplätze geschaffen werden. Das BMU-Umweltinnovationsprogramms fördert Demonstrationsvorhaben in großtechnischem Maßstab, die erstmalig aufzeigen, in welcher Weise fortschrittliche Verfahren zur Vermeidung oder Verminderung von Umweltbelastungen verwirklicht werden können. Das Programm will zur Fortentwicklung des umweltrecht- lichen Regelwerkes und des Standes der Technik beitragen, indem es solche Maßnahmen unterstützt, die eine hohe Demonstrationswirkung aufweisen. Vorrang bei der Förderung haben kleine und mittlere Unternehmen. N Trimet Das Bundesumweltministerium stellt insgesamt gut 475.000 Euro aus seinem Umweltinnovationsprogramm für ein Projekt der Ohm & Häner Metallwerk GmbH & Co. KG im nordrhein-westfälischen Drolshagen zur Verfügung. Ziel des Vorhabens ist die Einführung eines neuartigen, umweltfreundlichen Verfahrens zur Sandaufbereitung in einer Aluminiumgießerei. Thomas Reuther, 50, ist zum Bereichsvorstand der Trimet Aluminium AG für den Bereich Automotive berufen worden. Er löste damit zum 1. Juli Matthias Rosenbaum ab, der das Unternehmen auf eigenen Wunsch verlassen hat. Reuther leitet bereits seit 2001 den Bereich Recycling des Unternehmens sowie den Altmetallhandel.

ALUMINIUM · 7-8/2008 NEWS IN BRIEF Record amperage at Årdal President and CEO Eivind Reiten sent the signal to the rectifier to increase amperage in new cells in the pilot plant at the Årdal Research Centre in June. The amperage was raised immediately to 420 kA, the highest amperage recorded at a Norwegian smelter. Reiten was launching Hydro’s pioneering research project involving a new technology for aluminium production: HAL4e. The new cell technology is energy efficient, giving considerably lower climate gas emissions, and it is also cost efficient. It has been developed by Hydro’s scientists in Årdal, with the support of the company’s research centres in Porsgrunn, Norway, and Neuss in Germany. This next-generation production technology will be the company’s ace in the struggle for technological supremacy in the aluminium industry. It is very cost-efficient and, because the cells can be placed closely together, it saves in building space and logistics. The research project involves six trial cells that are now all in operation and producing metal. While the normal amperage in an aluminium reduction plant is around 300 kA, the amperage in HAL4e is all of 420 kA. Hydro’s ambition is to exceed even this, and attain 450 kA in a few years’ time. The high amperage is one of the most important reasons for the costefficiency of the HAL4e technology. The research project will continue over several years and, if the results justify it, then in 2011 the research scientists will commission a trial potroom containing 50 new cells. If all goes well then, it will be possible to base the first smelter Hydro builds after 2014 on the new generation technology. N Fred McDonogh re-elected EAFA President EAFA Sustainability takes centre stage EAFA President Fred McDonogh Fred McDonogh, Hydro Aluminium’s head of business unit foil, has been re-elected President of the European Aluminium Foil Association (EAFA) ALUMINIUM · 7-8/2008 for a second term. At the association’s annual conference McDonogh stated: “We have designed a proactive strategy to address many of today’s challenges including light-weighting, carbon footprint and resource efficiency all of which play an important role in ensuring the sustainability of our products.” McDonogh, who was also re-elected chairman of the Roller Group, added: “The pressure on the packaging sector to examine its environmental footprint has never been higher. That is why, among the many initiatives undertaken in 2007, several life cycle assessments (LCA) of food products packed in alufoil and flexible packaging were completed.” The Study ‘LCA of Packed Food Products: the function of flexible packaging’ (an executive summary was published in ALUMINIUM 4/2008, p. 58-61) was conducted by ESU-services. It takes into account • processing, packaging, and transportation to final production and packaging; • transport to retailers and households; • consumption in the home. While continuous improvement of processes and products is state of the art in the foil and flexible packaging industry, the case studies in fact prove that these types of packaging are highly resource efficient. McDonogh said: “The balance is really impressive if you manage to protect and save food with relatively low investment in resources for packaging compared to those needed to produce and distribute the food.” N 9 WIRTSCHAFT 10 ALUMINIUM · 7-8/2008 To power your operation while lowering consumption we provide you with stable highly efficient electrical energy supply, distribution and conditioning.

Aus dieser Sicht ist das Ergebnis einer aktuellen Umfrage des Branchenverbandes wgm bei seinen Mitgliedern von Interesse. Nachstehend sind die wichtigsten Ergebnisse zusammengefasst. Seit mehreren Jahren befragt der wgm seine Mitglieder über die Wirtschaftssituation im Unternehmen und fasst die Einzeldaten zu einem Gesamtbild zusammen. Die im Rahmen der Umfrage gewonnen Informationen geben Aufschluss über die wirtschaftliche Lage des NE-Metallhalbzeughandels sowie der Verarbeiter. Sie sind ein Baustein für konjunkturelle Analysen. Geschäftslage: Mittelfristig überwiegt Optimismus in den kommenden drei Monaten. Nur noch 5 Prozent prognostizieren eine Verschlechterung. Der Saldo aus positiven und negativen Erwartungen betrug zu Beginn des ersten Quartals +15, zu Beginn des zweiten Quartals liegt er bei +33. Damit hat der Optimismus im Handel mit Aluminiumhalbzeug insgesamt an Auftrieb gewonnen. Lagerhaltung: Unternehmen planen Abbau der Bestände Die aktuelle Lagerhaltung des Handels mit Aluminiumhalbzeug wird als ausgeglichen beurteilt (62%). Als hoch beurteilten nur noch 33 Prozent der Unternehmen die Bestände, als überhöht kein Unternehmen mehr. Im ersten Quartal waren dies noch 44 Prozent bzw. 8 Prozent. Neu ist auch, dass 5 Prozent der Unternehmen ihren Lagerbestand als gering einstuften (Abb. 4). Der Lagerhaltungsindex befindet sich gegenwärtig mit einem Wert von 152,9 auf einem historisch hohen Niveau. Der Anstieg des Index hat sich allerdings abgeflacht. Das bedeutet, dass immer mehr Unternehmen ihre Lagerbestände reduziert haben. In den zurückliegenden Jahren bestand zwischen der Entwicklung der Lagerhaltung und den Geschäftserwartungen ein Zusammenhang: Wurden die Geschäftserwartungen pessimistisch beurteilt, wurden die Bestände als zu hoch eingestuft und reduziert. Dieser Zusammenhang besteht gegenwärtig nicht mehr. Obwohl die Mehrheit Grafiken: wgm Die Geschäftslage des Metallhandels mit Aluminiumhalbzeugen hat sich nach Einschätzung der Unternehmen, im Vergleich zum ersten Quartal, nicht grundlegend verändert: 9,5 Prozent der befragten Unternehmen beurteilten die Konjunktur schwungvoller als noch vor drei Monaten, ebenfalls 9,5 Prozent sehen eine Abkühlung der wirtschaftlichen Dynamik. Beim Großteil der Unternehmen (81%) hat sich die wirtschaftliche Lage zu Beginn des zweiten Quartals im Vergleich zum Vorquartal hingegen nicht verändert (Abb. 1). Der Index zur Geschäftslage zeigt zugleich, dass die Konjunktur im Handel mit Aluminiumhalbzeug weder an Schwung gewonnen noch verloren hat. Dieses Ergebnis steht im Widerspruch zu der Entwicklung verschiedener wichtiger Indizes der Zulieferindustrien des Halbzeughandels. So stiegen der Produktionsindex der gewerblichen Wirtschaft und die ifo Geschäftslage im Durchschnitt des ersten Quartals an. Die Entwicklung der Indizes deutet auf eine steigende konjunkturelle Grunddynamik der deutschen Wirtschaft insgesamt hin. Auch andere Indizes lassen darauf schließen, dass die deutsche Wirtschaft mit viel Schwung in das Jahr 2008 gestartet ist. Zwar hat die Unsicherheit an den Finanzmärkten einige Umfragedaten deutlich eingetrübt. Im langfristigen Vergleich zeigt sich jedoch, dass die positiven Impulse im ersten Quartal 2008 nach wie vor kräftig waren und die Dynamik im Vergleich zum vierten Quartal 2007 gestiegen ist. So haben sich die Auftragsbestände im Schlussquartal des vergangenen Jahres erneut vergrößert. Die insgesamt positive Grundtendenz der Konjunktur zeigt sich schließlich weiterhin auf dem Arbeitsmarkt. Die Zuversicht für einen dynamischeren Konjunkturverlauf im Verlauf des zweiten Quartals 2008 ist jedoch deutlich gestiegen (Abb. 2 und 3). 38 Prozent der Unternehmen erwarten eine positivere Geschäftsentwicklung Abb. 1: Geschäftslage Aluminiumhalbzeug, Angaben in % 14 Abb. 2: Geschäftserwartungen Aluminiumhalbzeug, Angaben in % ALUMINIUM · 7-8/2008 WIRTSCHAFT Quartal und damit weiter von seinem langjährigen Durchschnittswert von 84,8 Punkten entfernt. Am Verlauf des Index ist erkennbar, dass sich die Neigung, Bestände abzubauen, seit dem 1. Halbjahr 2007 beschleunigt hat. Vom zweiten Halbjahr 2005 bis zum zweiten Halbjahr 2006 waren die Unternehmen hingegen bemüht, Lager zu füllen. Seit dem zweiten Halbjahr 2006 hat der Abbau von Lagerbeständen Vorrang. Eine Erklärung könnten auch hier das hohe Niveau der Metallnotierungen, die Sorge vor einem starken Preisrückgang und die verbesserte Versorgungslage mit Halbzeugen sein. Abb. 3: Index der Geschäftserwartungen Aluminiumhalbzeug ihre Geschäftserwartungen positiv beurteilt, werden die Bestände als zu hoch eingestuft. Verantwortlich für diese Einschätzung könnte das hohe Niveau der NE-Metallpreise und kürzere Lieferzeiten der Halbzeugwerke sein. Im dritten Quartal wird die Mehrzahl der Unternehmen weiter Lagerbestände abbauen (38%). Gut die Hälfte der Händler wird das aktuelle Bestandsniveau halten. Nur 10 Pro- zent wird das dritte Quartal dazu nutzen, Vorräte aufzubauen. Im Vergleich zum zweiten Halbjahr 2007 hat der Lagerdruck weiter abgenommen. Damals waren es noch 59% der Unternehmen, die Bestände abbauen wollten (Abb. 5). Der Trend des Lagerindex ist seit mehreren Jahren rückläufig. Der Wert des Index liegt gegenwärtig bei 72,7 Punkten, nach 74,8 Punkten im ersten Steigende Einkaufs- und stagnierende Verkaufspreise Die Einkaufspreise des Halbzeughandels werden in den kommenden Monaten auf ihrem gegenwärtigen Niveau bleiben (43%) oder sogar leicht steigen (38%), so dass Ergebnis der Umfrage. Nur 19 Prozent der Unternehmen rechnen mit sinkenden © Abb. 4: Lagerhaltung Aluminiumhalbzeug, Angaben in % Abb. 5: Trend Lagerhaltung Aluminiumhalbzeug, Angaben in % Abb. 6: Trend Einkaufspreise für Aluminiumhalbzeug, Angaben in % Abb. 7: Trend Verkaufspreise für Aluminiumhalbzeug, Angaben in % ALUMINIUM · 7-8/2008 15 WIRTSCHAFT Einkaufspreisen für Aluminiumhalbzeug. Anfang des ersten Quartals 2008 erwarteten noch 64 Prozent der Unternehmen sinkende Preise (Abb. 6). Der Trend Einkaufspreisindex gibt darüber Auskunft, ob die Mehrheit der Unternehmen in den kommenden drei Monaten mit steigenden oder fallenden Einkaufspreisen für Aluminiumhalbzeug rechnet. Dieser Index steigt seit dem zweiten Halbjahr 2003 an. Im ersten Halbjahr 2007 lag er auf einem historisch hohen Wert von 180,4 Punkten. Danach schlugen die Erwartungen um und der Index fiel. Gegenwärtig steigt der Index wieder an, da die Mehrzahl der Unternehmen mit steigenden Einkaufspreisen für Aluminiumhalbzeuge kalkuliert. Die Erwartung sinkender Verkaufspreise für Aluminiumhalbzeug ist nicht mehr dominant (Abb. 7). Rechnete zu Beginn des ersten Quartals noch eine überwiegende Zahl der Händler mit tendenziell sinkenden Verkaufspreisen, so besteht aktuell ein Gleichgewicht zwischen der Erwartung sinkender und steigender Verkaufspreise. Zu Beginn des ersten Quartals 2008 rechneten noch 57 Pro- zent der Unternehmen mit sinkenden Preisen. Heute sind dies nur noch 24 Prozent. Der Großteil der befragten Unternehmen erwartet, dass sich die Verkaufspreise auf ihrem gegenwärtigen Niveau verfestigen. Die Einschätzung, stark steigende Einkaufspreise in gleichem Maße auf die Verkaufspreise übertragen zu können, bleibt begrenzt. Auch aktuell rechnet die Mehrzahl der Unternehmen eher damit, dass die Einkaufspreise für Halbzeuge steigen, die Verkaufspreise dagegen stagnieren werden. P. Johne Halbzeugkonjunktur weiterhin auf hohem Niveau Die ersten fünf Monate 2008 brachten für die deutschen Aluminiumhalbzeugunternehmen verglichen mit dem entsprechenden Vorjahreszeitraum insgesamt zwar eine leichte Abschwächung der Auftragseingänge. Diese Abschwächung wird jedoch als Basiseffekt bewertet. Die ersten Monate 2007 waren außergewöhnlich stark und es wurden Aufträge weit über den vorhandenen Kapazitäten gebucht. Die nun zu beobachtenden leichten Rückgänge der Auftragseingänge finden auf einem weiterhin sehr hohen Nachfrageniveau statt. „Die Überhitzungsphase aus dem Vorjahr hat zunächst ein Ende gefunden. Die Kapazitäten sind insgesamt jedoch gut ausgelastet. Das zeigen die Ablieferungen, die noch leicht zuge- 16 nommen haben“, so Wellner. In den 34 Aluminiumhalbzeugunternehmen, die an 47 Standorten in Deutschland tätig sind, waren Anfang 2008 rund 16.400 Mitarbeiter beschäftigt. Die Unternehmen produzieren Walzprodukte (Bleche, Bänder, Platten), Strangpressprodukte (Profile, Stangen, Rohre), Drähte und Schmiedeteile. Walzhalbzeug auf hohem Niveau Besser als die Auftragseingänge spiegeln die Produktionsdaten die aktuelle Situation wider. Der höchste Anteil an der Halbzeugproduktion entfällt auf die Walzwerke, für die 2007 erneut ein Erfolgsjahr war. Mit 1,90 Mio. Tonnen lag die Jahresproduktion nur knapp unter dem bisherigen Rekordniveau des Jahres 2006 (1,92 Mio. t). Damit halten die deutschen Walzwerke mehr als ein Drittel an der europäischen Walzproduktion. Getragen wird die gute Nachfrage nach Walzhalbzeugen zurzeit auch durch die gute Binnenkonjunktur, die besser verläuft, als von Analysten gelegentlich behauptet. Im Jahr 2007 zeigte sich der Auftragseingang, der in den vergangenen Jahren deutlich zugenommen hatte, gemessen an dem hervorragenden Vorjahr erstmals seit langem schwächer. Er nahm im Ausland um 11,9 Prozent gegenüber dem Vorjahr ab. Im Inland konnte der Auftragsein- gang dagegen um 1,7 Prozent gesteigert werden. Damit gewann die binnenwirtschaftliche Entwicklung in Deutschland für die deutsche Aluminiumwalzindustrie wieder mehr an Bedeutung. Größter Abnehmer von Aluminiumwalzhalbzeugen ist der Verpackungssektor (39%) vor Transport und Verkehr (19%) und dem Handel (18%). Der verbleibende Teil des Bedarfs geht zu etwa gleichen Anteilen von 11 Prozent in den Bausektor GDA Mit 2,52 Mio. Tonnen verzeichneten die 34 deutschen Aluminiumhalbzeugwerke 2007 eine neue Rekordproduktion. „Auch für 2008 erwarten die Hersteller von Aluminiumhalbzeugen einen guten Konjunkturverlauf“, berichtete Christian Wellner, Geschäftsführer des Gesamtverbandes der Aluminiumindustrie (GDA), Düsseldorf, in einem aktuellen Pressegespräch anlässlich einer Werksbesichtigung bei F. W. Brökelmann Aluminiumwerk. Friedrich W. Brökelmann ist Präsident des GDA und zugleich Vorsitzender des Fachverbandes Aluminiumhalbzeug. GDA-Geschäftsführer Christian Wellner: „Die Halzbzeugkapazitäten sind gut ausgelastet.“ sowie in den Maschinen- und Anlagenbau. „Insgesamt verzeichnen die deutschen Aluminiumwalzhalbzeughersteller seit etwa zehn Jahren ein stetes Mengenwachstum von durchschnittlich rund fünf Prozent pro Jahr“, erläuterte Wellner. In den einzelnen Produktgruppen war die ALUMINIUM · 7-8/2008 Insgesamt rechnen die Hersteller von Walzhalbzeug mit einer leichten Zunahme des Bedarfs Entwicklung 2007 uneinheitlich. Bei Platten nahm die Produktion um 7,1 Prozent zu, bei Blechen gab es einen Rückgang um 7,6 Prozent. Der men- genmäßig wichtigste Bereich der Bänder gab um 0,6 Prozent leicht nach.

Innerhalb der vergangenen 15 Jahre hat sich die Produktion von Aluminiumwalzhalbzeug in Deutschland mehr als verdoppelt. Für 2008 sind die Walzhalbzeughersteller optimistisch, das hohe Niveau zu halten. Die Binnennachfrage hatte sich in den ersten Monaten auf gutem Niveau stabilisiert, die Auslandsnachfrage entwickelt sich ebenfalls fest. Die wichtigen Abnehmerbranchen wie Verpackung oder Fahrzeugbau erwarten für 2008 eine gute Branchenentwicklung. Insgesamt rechnen die Hersteller von Aluminiumwalzhalbzeug für 2008 mit einer leichten Zunahme des Bedarfs.

INDIVIDUELLE LÖSUNGEN AUS ALUMINIUM 17 folgreich. Die gute konjunkturelle Lage hat auch bei den deutschen Strangpressern zu Rekordmengen geführt. Die Produktion von Profilen, Stangen und Rohren stieg um 5,3 Prozent auf 600.400 Tonnen (2006: 570.300 t). Getragen wurde dieser Produktionszuwachs ebenfalls von der guten Binnennachfrage sowie durch die gute Exportkonjunktur des verarbeitenden Gewerbes in Deutschland. Die Strangpresswerke waren teilweise so stark ausgelastet, dass Lieferzeiten von mehr als einem halben Jahr in Kauf genommen werden mussten. Nach Angaben des GDA stieg der Gesamtverbrauch an Strangpressprodukten in Deutschland in den vergangenen Jahren kontinuierlich an. 2002 und 2003 hatte der Verbrauch noch jeweils 543.000 Tonnen betragen; 2006 war er dann auf etwa 718.000 Tonnen und 2007 auf rund 756.000 Tonnen gewachsen. Für 2008 und 2009 erwartet der GDA eine Stabilisierung auf diesem hohen Niveau. In den ersten Monaten des laufenden Jahres zeigte sich die Binnennachfrage stabil, das Auslandsgeschäft war außerordentlich stark. Die wichtigsten Profilmärkte liegen im Bausektor (30%), im Verkehr (28%), im Maschinenbau (9%) und in der Brökelmann WIRTSCHAFT Die deutschen Pressewerke haben ihre Wettbewerbsfähigkeit in den vergangenen Jahren deutlich gesteigert Elektrotechnik (8%). Darüber hinaus liefern die Strangpresser in die verschiedensten Nischenmärkte. Die Herausforderungen wurden beeindruckend gemeistert Die vorliegenden Zahlen zeigen auf bemerkenswerte Weise, dass die deutschen Presswerke ihre Wettbewerbsfähigkeit in den vergangenen Jahren deutlich gesteigert haben. Die Situation im Strangpressmarkt hatte die Brachenunternehmen im vergangenen Jahrzehnt vor besondere Herausforderungen gestellt. Im Wettbewerb mit Anbietern, die an Standorten mit deutlich niedrigeren Kosten produzieren konnten, mussten die hiesigen Presswerke darüber nachdenken, wie sich durch gezielte Rationalisierung Kosten einsparen lassen. „Diese Aufgaben wurden von der ganz überwiegend mittelständisch strukturierten Branche mit Bravour erledigt“, betonte Wellner. In einem modernen Semis business in Germany still at a high level With 2.52 million tonnes the 34 aluminium semis plants in Germany achieved a new production record in 2007. For 2008 too, the manufacturers of aluminium semis expect the business situation to remain healthy, according to the branch association GDA. Compared with the corresponding period of the previous year, in the first five months of 2008 semis production companies in Germany saw a slight downturn of order intakes. This, however, is regarded as a consequential effect because in the first months of 2007 orders far above the existing capacities were booked. “The overheat phase from last year has now come to an end. However, capacity utilisation is good, as shown by delivery figures which are slightly up”, says Christian Wellner, Executive Director of GDA. 18 The largest proportion of semis production is accounted for by rolling plants. With 1.90 million tonnes the year’s production was only just below the previous record level of 2006 (1.92m t). Rolling plants in Germany accounted for more than a third of rolled product manufacture Europe-wide. Rolled semis manufacturers are optimistic that this high level will be maintained in 2008. In the first months domestic demand stabilised at a high level and demand from abroad also developed steadily. Overall, aluminium rolled semis producers expect a slight increase of demand in 2008. For aluminium extrusion plants too, 2007 was again a successful year. The good trade position led to record output from extruders in Germany as well. The production of sections, rods and tubes in- creased by 5.3% to 600,400 tonnes (2006: 570,300 t). Some extrusion plants were so heavily loaded that delivery times in excess of half a year had to be tolerated. For 2008 and 2009 the GDA expects business to stabilise at this high level. The above figures demonstrate strikingly that extrusion plants in Germany have substantially increased their competitiveness in recent years. The situation in the extrusion market presented companies in the branch with particular challenges during the decade gone by. In competition with suppliers who produce in countries where costs are considerably lower, extrusion plants in Germany have greatly improved their cost structure by well-directed rationalisation measures. At present 84 extrusion presses are in productive operation in Germany. ALUMINIUM · 7-8/2008 WIRTSCHAFT Pressbetrieb ist der vollautomatisierte Ablauf, vom Bolzenlager bis hin zum gesägten, in Körben gestapelten Profilabschnitt heute Standard. In diesem Bereich genügt eine einzige Bedienungsperson zur Überwachung der gesamten Linie. Vor kaum drei Jahrzehnten waren dazu noch bis zu zehn Personen notwendig. „Neben der innovativen Strangpresstechnik ist die hohe Kundenorientierung eine der Stärken der Branche. Die Strangpresser bieten hohe Qualität, suchen die direkte Nähe zum Kunden und verfügen über eine hohe Beratungskompetenz“, sagte Wellner. F. W. Brökelmann unterstrich diese Einschätzung und verwies darauf, dass sich die Stimmung der Branche und das Vertrauen der gesamten deutschen Industrie in den Standort Deutschland inzwischen deutlich gebessert habe. „Wir haben die Globalisierung bislang gut bewältigt“, sagte er und verwies darauf, dass der Anteil der Lohnkosten an den Gesamtkosten in den vergangenen Jahren, gerade auch aufgrund der durchgeführten Rationalisierungsinvestitionen, heute deutlich geringer sei – und zwar zwischen fünf und 15 Prozent, je nach Profil, liege – und die Branche dadurch entsprechend wettbewerbsAnzeige www.inotherm-gmbh.de fähiger geworden sei. Entsprechend würden die Strangpressunternehmen verstärkt in Deutschland statt in Schwellenländern investieren, wo das Geschäftsrisiko mit Blick auf die geforderte Produktqualität und eine ungenügend ausgebildete Belegschaft relativ hoch sei. In dem wachsenden Markt für Strangpressprodukte gibt es zahlreiche Anbieter. Nicht nur die traditionellen europäischen Anbieter, auch ost- und südosteuropäische Hersteller drängen zunehmend auf den Markt. Die wichtigsten Marktteilnehmer sind allerdings große internationale Aluminiumkonzerne, doch gibt es daneben eine Vielzahl unabhängiger, mittelständischer Strangpressunternehmen. In Deutschland selbst produzieren derzeit 84 Strangpressen. Für das laufende und auch kommende Jahr erwarten die Strangpressunternehmen wieder eine gute Mengenkonjunktur, die ihre Impulse aus Märkten wie dem Maschinen- und Anlagenbau, der Solartechnik und dem Fahrzeugbau erhält. Der Preis für Aluminium bereite keine Sorgen: Die Metallsituation bleibe zwar angespannt und der Aluminiumpreis absehbar auf hohem Niveau, doch gelte dies für potenzielle Substitutionswerkstoffe in ähnlicher Weise. Die Energiepreise spielten gemessen an den Veredelungskosten eine untergeordnete Rolle, bei Brökelmann liegen sie dem Firmenchef zufolge bei rund 15 Prozent. Alles in allem also positive Aussichten für die Branche. N Brökelmann bleibt auf Wachstumskurs Deutliches Wachstum im Automotive-Geschäft angepeilt / Investition in eine neue 22/24-MN-Strangpresse F.

Brökelmann, Geschäftsführer und Inhaber von Brökelmann Aluminium 19 WIRTSCHAFT Anlagen- und Gerätebau, nicht zuletzt Zukunftsbranchen wie die Medizintechnik sowie Luft- und Raumfahrt. Automotive inzwischen das dominierende Geschäft Aus der steigenden Nachfrage nach Aluminium im Automobilsektor ergeben sich für das Unternehmen gute Wachstumsmöglichkeiten, da man sich auf die Erfordernisse der Automobilbranche ausgerichtet hat und über langjährige Erfahrung in der Kooperation mit führenden Automobilherstellern verfügt. Die Weichen für das Automotive-Geschäft wurden bereits Mitte der 1990er Jahre mit der Modernisierung und Erweiterung des Maschinenparks und der technischen Anlagen gestellt. Dieses Geschäft mit technologisch anspruchsvollen Produkten ist Ausdruck einer Qualitätsstrategie, die sich bewusst von einer rein auf Menge abzielenden Geschäftspolitik abwendet, in der der Preisdruck deutlich höher ist. „Heute erzielen wir rund 50 Prozent unseres Umsatzes im Bereich Automotive – mit einem breiten Die 27-MN-Schloemann-Presse mit Elhaus-Anwärmofen und nachgelagertem I.A.S.-Induktionsofen zur Aufbringung eines variablen und präzisen Temperaturprofils auf den Pressbolzen Spektrum an hochwertigen Produkten wie Dach- und Zierleisten, Sitzführungsschienen oder Airbaggehäusen. Wir forschen ständig weiter und entwickeln neue Anwendungsmöglichkeiten und Legierungen, um die Märkte von morgen zu bedienen“, erläutert Friedrich W. Brökelmann, Geschäftsführer und Inhaber von Brökelmann Aluminium. Und ergänzt, dass man auf diese Weise auch auskömmliche Erlöse in einem üblicherweise als schwierig bezeichneten Geschäft erzielen kann. Zu den erfolgreichen Entwicklungsanstrengungen zählt u. a. die neue Legierung „Duktal“ – eine Legierung, die sich durch höchste Brökelmann Aluminium remains on course for growth F.W. Brökelmann Aluminium (FWB) manufactures high-grade aluminium sections as semis and in processed form, with an annual output of the order of about 23,000 tonnes. In the business year 2007/08 the company, which employs 310 people, made a turnover of around 95 million euros. Technologically, FWB is right up to the mark. In recent years the semis plant has been extended systematically to become one of the most efficient extrusion plants in Germany. The cornerstones of the mediumsized aluminium processor are three SMS presses with extrusion loads of 17, 20 and 27 MN and integrated further processing facilities. The automotive industry has developed into FBW’s most important market, with double-digit growth rates in that business. The company’s declared aim is to grow still more in the sector. Today, already 50 percent of turnover comes 20 from automotive business. The product range extends from roof and decorative trim strips, through seat guide-rails, to complete air-bag housings. With the new alloy ‘Duktal’ FBW has developed a material notable for maximum strength and ductility, with the outstanding crumpling properties that are essential for crash components. Duktal extrusions have strength values of Rm > 319 MPa and Rp0.2 > 280 MPa. Meanwhile, the automobile manufacturer Audi has approved the alloy. An important project is the extension of technical further processing to include stretch-bending technology, a multidimensional bending process which offers a great deal in terms of design and shaping. The first orders from the automotive sector have already come in from a noted sports car manufacturer. This is an indication of FBW’s desire to grow still more in the area of further processing. In addition, the company is investing to increase its capacity in the product sector of extruded annular tubes. The production of endless extruded aluminium tubes began in 2004. For this, directly behind the 20 MN press a plant has been set up which consists of five winding devices one after another. Since then endless extruded aluminium tubes with diameters between 14 and 32.5 mm are being produced. The existing plant was extended this year. With its new investment in a new 22/24 MN extrusion press as a replacement for the 17 MN press, which is getting a bit long in the tooth, FBW will keep its machine park to the top level. The investment, amounting to 4.5 million euros, is scheduled to begin operating at the end of 2009 or early in 2010 – just at the right time for the company’s centenary.

Mit Duktal erreichen die Strangpressprofile von Brökelmann Festigkeiten von Rm > 310 MPa und Rp0,2-Werte > 280 MPa. Der Automobilhersteller Audi hat diese Legierung inzwischen freigegeben. Insgesamt hat Brökelmann 18 Legierungen im Einsatz. Außerdem ist Brökelmann nach ISO TS 16949:2002 auditiert. Das ist die höchst mögliche Auditierung und zugleich Grundvoraussetzung für die Belieferung der Automobilhersteller mit Premiumprodukten. Um seine Produkte weiterzuentwickeln und optimal auf die Kundenwünsche abzustimmen, setzt Brökelmann auf den intensiven Dialog mit Kunden und Geschäftspartnern. So präsentierte sich FWB im Juni dieses Jahres als Aussteller auf der Eurolite in Salzburg, der europäischen Fachmesse für den Konstruktionsprozess und die Serienfertigung von Leichtbauteile. Dort wurden industrielle Leichtbauwerkstoffe, Konstruktions- sowie Fertigungstechnologien vorgestellt und in hochrangig besetzten Expertengremien diskutiert. Um den Anforderungen der Märkte noch besser gerecht zu werden, hat Brökelmann in die Verbesserung der betrieblichen Logistik investiert.

Zudem werden über ein rechnergestütztes Lagermanagement Anforderungen wie FiFo (First in, First out) oder Just in time besser erfüllt. Ein weiteres Projekt ist der Ausbau der technischen Weiterbearbeitung um die „Streckbiegetechnologie“, einem multidimensionalen Biegeprozess mit höchstem Anspruch an Design und Formgebung. Erstaufträge aus dem Automotive-Sektor von einem namhaften deutschen Sportwagen-Hersteller liegen bereits vor. Hier zeichnet sich ab, dass Brökelmann auch in der Bearbeitung weiter wachsen will. Die FWB-Kompetenz zeigt sich hier neben innovativen Stanzwerkzeugen auch in den modernsten Messtechniken, die zum Einsatz kommen. Die zu Brökelmann gehörende Innotec, Sitz in Dortmund, die sich der Weiterbearbeitung und vertiefenden Wertschöpfung widmet, wurde von ursprünglich vier auf heute 70 Mitarbeiter erweitert. der Produktion von endlos stranggepressten Aluminiumrohren hat Brökelmann Anfang 2004 begonnen. Dazu wurde direkt hinter der 20-MNStrangpresse eine Anlage aufgebaut, die aus fünf hintereinander aufgestellten Haspeleinrichtungen besteht. Seitdem werden endlos gepresste Aluminiumrohre mit Durchmessern zwischen 14 und 32,5 mm produziert. Die vorhandene Anlage wurde in diesem Jahr erweitert.

N Schweizer Aluminiummarkt wächst weiter Der Schweizer Aluminiummarkt wuchs im vergangenen Jahr um 5,8 Prozent gegenüber dem Rekordjahr 2006. Damit wurden rund 191.500 Tonnen Aluminium in der Schweiz eingesetzt. Das entspricht einer Pro-Kopf-Menge von 25,5 Kilogramm. Allein die drei Schweizer Press- und zwei Walzwerke produzierten 2007 212.500 Tonnen (+5,3%). Die Schweizer Leichtmetallgießer verarbeiteten 23.228 Tonnen (+11%), auch dies ein Halbzeugablieferung Schweiz 22 neuer Höchstwert; der Sandguss legte um 3,6 Prozent zu, der Kokillenguss um elf Prozent und der Druckguss um 13,5 Prozent. Die Steigerungen spiegeln die hohe Nachfrage nach Schweizer Aluminiumgussteilen in der Maschinenbau- und Elektroindustrie, im Energie- und Automobilsektor wider. Wie Markus Tavernier, Präsident des Aluminium-Verbandes der Schweiz, auf der Jahrespressekonferenz des Verbandes erläuterte, wurde zudem in größere integrale Teile und Druckgießanlagen sowie in höhere Wertschöpfung durch Bearbeitung von Teilen, Baugruppen und Montagen investiert.

Im Bauwesen begegnen alle führenden Schweizer Systemanbieter mit ausgeklügelten, neuen Entwicklungen den steigenden ökologischen Anforderungen und Vorschriften. In diesen Prozess einbezogen ist auch die Hochschule Luzern Technik & Architektur (HTA) mit dem Forschungsprojekt „Aluminiumfenster der Zukunft“. Bei Verpackungen wurde 2007 ein leichtes Plus von rund zwei Prozent erreicht. Für 2008 erwartet Tavernier ähnlich hohe Wachstumsraten wie 2007. Neben der weiter steigenden weltweiten Automobilproduktion sieht er auch im Flugzeugbau langfristig günstige Absatzchancen für den Einsatz von Aluminium – sowohl durch hochfeste, leichte Aluminiumlegierungen als auch durch den kombinierten Einsatz von Verbundwerkstoffen. N ALUMINIUM · 7-8/2008 ECONOMICS Aluminium traders expect output costs to rise until 2013 Record energy prices and power failures from China to South Africa are leading to mounting concerns that aluminium supplies will be curtailed within five years as production costs increase. Aluminium for delivery in 2013 rose 5% in May on the London Metal Exchange, the most in three months. The US$147 increase in the contacts to US$3,110 a metric tonne contrasts with a 0.9% gain in the cash market for immediate delivery. Deutsche Bank AG raised its aluminium forecasts end of March from this year through 2012 by between 8% and 13% after oil surpassed US$100 a barrel. Snowstorms and May’s earthquake curbed output in China, and South African power shortages delayed the start of a new smelter. Energy now accounts for about 40% of aluminium production costs, compared with 30% in 2007, according to Barclays Capital. Supply will expand at 4.5% in 2008, compared with 12% in 2007, according to a 12 May forecast by Citigroup Inc. About 560,000 tonnes of output was lost in China, according to estimates by London-based researcher CRU. The shortfall is greater than the 381,000 tonnes of surplus built up in the first quarter, according to the World Bureau of Metals Statistics. Rio Tinto Alcan, the world’s second-largest producer, delayed work on its US$2.7bn Coega smelter project in South Africa after the nation’s staterun utility failed to guarantee power for the plant. Saudi Arabian Mining Co. postponed the start of its aluminium venture with Rio Tinto Alcan until 2012 because the power plant that will supply the project won’t be ready until the end of 2011. Aluminium demand is expanding 6% annually, so delays increase concern about supply through 2010, Barclays said. Six new smelters need to be built each year to meet demand, based on the average plant being able to produce 500,000 tpy. Prices for immediate delivery rose 0.3% to US$2,884.25 in May because there’s no shortage now. Stockpiles monitored by exchanges in London, New York and Shanghai jumped 46% in a year. Even after the snowstorms and earthquake, CRU forecasts Chinese production will advance 17% this year. On average, Wall Street aluminium estimates remain below prices traded on the LME for delivery between 2009 and 2011. Cash prices will average US$2,879, US$2,875 and US$2,659 a tonne in 2009 through 2011, according to median of analyst estimates surveyed by Bloomberg. But prices for contracts to deliver in 2009 and beyond are now above US$3,000 a tonne. The price at which smelters begin to be unprofitable is in the “high US$2,000s” a tonne, said Richard Evans, CEO of Rio Tinto’s aluminium unit. In contrast LME options indicate prices are expected to rise to US$3,200 or more by December. Almost one-third of the call options, giving holders the right to buy, are for prices at US$3,500. N China to remain a net importer of primary aluminium China will continue to maintain its status as a net importer of primary aluminium throughout 2008, which will be mainly supported by growing aluminium product exports. According to the Ministry of Commerce, China imported 48,993 tonnes of primary aluminium in the first four months this year, down 9% from 2007, while it exported only 22,080 tonnes of primary aluminium during the same period, plummeting 70% yearon-year, which represents net imports of 26,913 tonnes during this period. China has been a net importer of primary aluminium since October 2007. An export tax of 15% levied on primary aluminium caused a sharp shrinkage of primary aluminium exports, and so pulled domestic aluminium prices down to levels much ALUMINIUM · 7-8/2008 lower than spot aluminium prices on the London Metal Exchange. Aluminium product processing trade has driven an increase in primary aluminium imports. This trade, also known as tolling, allows Chinese companies to import primary aluminium or aluminium scrap and to process them into finished products for reexport under favourable tax policies. China exported 150,000 tonnes of aluminium products in April, up 5.76% from the previous month. In the first four months, aluminium product exports saw 0.4% year-on-year growth to reach 610,000 tonnes. Most of the primary aluminium imports are manufactured into aluminium products destined for overseas markets. China’s primary aluminium aggregate consumption is well supported by the country’s huge aluminium product exports. China’s primary aluminium production reached 4.25m tonnes in the first four months, up 10.9% a year before. China’s 2008 primary aluminium production will come to 14.8m tonnes, up 16% from 2007. However, the predicted figure was around 800,000 tonnes lower than previously forecast at the beginning of this year, based on assumptions including a 500,000tonne loss caused by the snowstorms and a 60,000-tonne loss due to the earthquake. China’s demand for primary aluminium in 2008 is expected to grow in excess of 22% on last year’s 12.3 million tonnes, outpacing a forecast of 8.9% year-on-year growth for global demand, which is expected to hit 41.1 million tonnes. China would be a net primary aluminium importer of 1 million tonnes by 2012. paw 23 ECONOMICS Bauxite and alumina activities in 2007, Part II R. P. Pawlek, Sierre This overview covers the activities and developments in the bauxite and alumina industry during the year 2007. Part I was published in ALUMINIUM 6/2008 covering the regions Africa, North and South America and Middle East. ASIA Indonesia: In March 2007 PT Antam and its partners signed an agreement to form PT Indonesia Chemical Alumina (ICA) to study the feasibility of a refinery project. Antam owns 49% of the project, while Japan’s Showa Denko owns 30%, Singapore’s Straits Trading Amalgamated Resources 15% and Japan’s Marubeni the remaining 6%. The project has a targeted capacity of 300,000 tpy of chemical grade alumina, but this may change with the feasibility study, which so far has to deadline for completion. Construction was expected to begin in late 2007 and commercial production at the beginning of 2010. The plant will be built in Tayan in West Kalimantan, Indonesia. In August 2007 the Indonesian central government ordered a halt to bauxite mining in the west of Bintan Island, one of Indonesia’s two main production bases, and a major supplier to alumina refineries in China. The bauxite mining area in west Bintan normally produces around 10m tpy of bauxite in total. Output in the other parts of Bintan, where production is continuing, is estimated at 2.4m tpm. The local government had issued licences allowing seven to eight bauxite miners to mine that land, but the central government wants the land set aside for a water project. About 15 mines were affected by the government directive. The mines can now only sell bauxite from stock, but are not allowed to mine further. China imported around 30% of its bauxite requirements in 2006, but this could rise by 50% in 2007 on China’s expanding alumina refinery capacity and falling 24 domestic bauxite grades. Imports increased 4.5 times to 9.68m tonnes in 2006, with Indonesia accounting for 8.81m tonnes or 91% of the imports. In September 2007, UC Rusal signed an MoU with PT Antam Tbk to construct a 3.6m tpy bauxite and 1.2m tpy alumina complex in West Kalimantan, Indonesia. Rusal will hold a 51% stake in the joint venture, with state-owned Antam holding the remaining 49%. The project will be constructed across bauxite deposits located in West Kalimantan. Rusal formed a working group in September both to confirm bauxite reserves at the two selected deposits and to complete the documentation required to establish the joint venture. An overall budget and financial assessment should be completed in 2009, allowing construction to begin in 2009 and first alumina output in 2011. Vietnam: In October 2007 UC Rusal intended to invest in a hydroelectric power plant and an integrated bauxite-to-aluminium facility in Vietnam’s southern Binh Phuoc province. The planned aluminium smelter would have a capacity of 750,000 tpy. The proposal is still at an early stage. Once approved, the projects will create jobs for thousands of workers. The Russian company is one of several drawn to Vietnam, which has significant reserves of bauxite. In November 2007 Vietnam reported that by 2015 it will build seven aluminium hydroxide processing plants and a bauxite-aluminium processing complex, which will have a total capacity of 8.4m tpy of alumina and 650,000 tpy of aluminium hydroxide. The decision to build the plants follows a government plan to exploit and process bauxite in the Central Highlands through 2025. The plants will cost between US$11.8bn and US$15.6bn. At least US$47.5m would be spent on completing the geological survey, US$9.9-13.7bn for building the mining and processing plants, and US$1.9bn for building infrastructure. The company developing the project will be equitised, with the Vietnamese government responsible for management. A dedicated port that can load vessels with 50,000 tonnes of bauxite will be built in central Binh Thuan Province to develop the industry in the Central Highlands and Southern Central regions. Environmentally friendly technology will be used to exploit 5.5bn tonnes of bauxite in the Central Highlands provinces. In November the Vietnam National Coal and Mineral Industries Group (Vinacomin) obtained a government licence to develop a US$490m bauxite mining project in Lam Dong province in the country’s central highlands region. The company is aiming to produce about 600,000 tpy of bauxite, with a start-up date in 2010. The Tan Rai bauxite mine in Bao Lam district is estimated to have reserves of over 176m tonnes. China: In May 2007 China announced it is likely to be self-sufficient in alumina supply within the following two years, and may even see excess supply surfacing. China has seen dramatic changes since 2006. China used to rely mainly on imports of alumina, with domestic supply dominated by Chalco (Aluminium Corp of China), but now imports are down and nonChalco alumina producers share the market with Chalco almost equally. Furthermore, based on the current expansion plans of numerous producers, China’s alumina capacity may reach up to 28 to 30m tpy in the near future, with capacity in 2007 likely around 18 to 20m tpy. Seven producers in Henan province are expanding, of which several had completed in 2006. Expansion works at four major producers in Shandong province, six producers in Shanxi province and five more in various other provinces were in progress or nearing completion. In January 2007 China’s Yunnan Aluminium Co postponed building its 800,000 tpy alumina refinery in Wenshan city in southern Yunnan province as a result of low alumina prices. Yunnan Aluminium had planned to ALUMINIUM · 7-8/2008 ECONOMICS start work on the first 400,000 tpy phase in 2006 with completion scheduled for the end of 2007 and commissioning in 2008. However, the company decided to delay the project because of dismal alumina prices and the need to ascertain the level of bauxite reserves at a new mining project in Wenshan. Even if the company reaches its required bauxite reserves at Wenshan it may not start mining immediately. In March 2007, China’s Shandong Aluminium intended to produce 1.5m tonnes of alumina in 2007, 14% more than in 2006. Of the total amount, 420,000 tonnes consist of chemical grade alumina, an increase of 5.7% compared with the previous year. Shandong Aluminium can raise output in 2007 as it plans to fully ramp up capacity on its new alumina project in the middle of the year, which will lift the company’s alumina capacity to 630,000 tpy from a previous 320,000 tpy. In November 2007, China announced guidelines for those who wish to enter the domestic aluminium industry, according to the National Development and Reform Commission. All new development projects in the aluminium sector, including mining, alumina refining, ingot melting and recycling, as well as fabrication plants, must abide by all requirements of the various state departments (Detailed report in ALUMINIUM 1-2/2008, p 24/25). AUSTRALIA In January 2007 Alcan updated its cost estimates and start-up schedule for the Gove alumina refinery expansion and upgrade in the Northern Territory, reflecting progress in the fourth quarter of 2006, additional tie-in requirements, and weather related delays. Alcan revised its cost estimates up to US$2.3bn and moved the start-up date from the first to the second quarter of 2007. The latest increase means costs have increased by some 53% from the original estimate. The project was approved in September 2004 and was approx. 95% complete, with estimated capital spending in 2007 of US$400m. It will increase the refinery’s capacity from 2m tpy to 3.8m tpy and is expected to bring Alcan’s internal alumina production capacity into balance with current requirements, and to reduce cash costs at Gove by US$30 per tonne. Expanded production ramp up started progressively during the second quarter of 2007 and continued through the first quarter of 2008. Saleable production in 2007 was forecast between 2.3m and 2.4m tonnes, representing an increase of about 500,000 to 600,000 tonnes compared to 2006’s level of 1.8m tonnes. The expansion of the Gove alumina refinery began commissioning in June 2007. The ramp-up to full capacity will © ALUMINIUM · 7-8/2008 Photos: Alcoa ECONOMICS Huntley mine, Western Australia, where Alcoa runs the world’s largest bauxite mine take about one year and will be linear. By the end of 2007 Gove expected to be running at above 3m tpy. In February 2007 Chinese aluminium producer Chiping Xinfa Huayu Alumina Co exercised an option agreement with Australia’s Metallica Minerals to buy a 10% stake in bauxite miner Cape Alumina. Metallica will retain a 40% stake in Cape Alumina, which owns the Wenlock bauxite deposit in Queensland. The remaining 50% of the company is owned by Anegada Metals Corp. The Wenlock project is still in the exploration stage and is part of the company’s Cape York bauxite project. Xinfa is the single largest bauxite importer in China, accounting for 5m tonnes of the 9.7m tonnes imported by the country in 2006. In March 2007 China’s largest independent alumina-aluminium producer Chiping Xinfa Huayu Alumina paid A$4.625m (US$3.585m) to Metallica Minerals Ltd to acquire 10% in Australian bauxite company Cape Alumina. Metallica Minerals will remain the largest shareholder in Cape Alumina with a 40% stake. Offtake negotiations with Xinfa started in April, subject to delineation of sufficient resources to justify the development costs and to an agreed price formula for the off-take bauxite. A scoping study into development of the Wenlock bauxite deposit is due to be completed in April. Traditional landowner negotiations are also progressing well. During the coming dry season 26 Cape Alumina will complete further drilling on newly granted tenements. This could substantially increase confirmed resources at Wenlock, which currently stand at 54m tonnes of in situ bauxite. In May 2007 Chiping Xinfa Huayu Alumina Co expanded its reach over bauxite prospects in Australia after affiliate Cape Alumina obtained additional exploration permits in Queensland’s Cape York Peninsula. The Queensland government granted Cape Alumina three additional exploration permits for minerals, covering parts of the Weipa bauxite plateau. Xinfa recently increased its stake in Brisbane-based Cape Alumina from 10% to 17.5%. Cape Alumina is targeting 20-30m tonnes of bauxite on the three tenements and 100-130m tonnes of resources at its existing Wenlock and Catfish Creek deposits, which are expected to yield 60-80m tonnes of dry product bauxite after beneficiation. Cape Alumina expects to complete drilling at the existing tenements in October 2007 in preparation for a full feasibility study in 2008. In February 2007 the government of Western Australia granted formal environmental approval for an expansion of the Wagerup alumina refinery. The expansion at Wagerup, would comprise the construction of a third production unit, lifting capacity from around 2.6m tpy to 4.7m tpy. AWAC has not yet formally approved the expansion, not least because of the tor- tuous proceedings around the plant’s environmental performance. Feasibility studies are currently underway, with a go-ahead decision likely early in 2008, but the environmental signoff is a major hurdle cleared. In May 2007 Alcoa launched a new emission-reduction technology called Carbon Capture at its Kwinana alumina refinery in Western Australia. Carbon Capture is an innovative residue treatment process that involves mixing bauxite residue with carbon dioxide. The Kwinana carbonation plant has the potential to lock up 70,000 tpy of CO2, the equivalent of eliminating the emissions of 17,500 automobiles. Alcoa plans to deploy the technology to its nine alumina refineries worldwide. Deployment across Alcoa’s Australian operations alone could potentially save 300,000 tpy of CO2. The Carbon Capture system was developed by Alcoa’s Technology Delivery Group which is based in Australia. The group discovered that by mixing CO2 into the bauxite residue, its pH level will be reduced to levels found naturally in alkaline soils. The improved environmental properties of the residue make it suitable for use as road base, building materials and to improve soil. Alcoa plans to share the technology with the aluminium industry which is also vital to its long term sustainability. In May 2007 Hydro signed an MoU with Australian mining company United Minerals Corporation (UMC) to explore the possibility of bauxite mining and alumina refining in the Kimberly region in Western Australia. The investment cost of the project is estimated at A$4-5bn (US$3.3-4.2bn) including associated infrastructure. A final agreement would give Hydro a 75% holding in a potential bauxite and alumina project, in line with Hydro’s strategy to grow in primary aluminium production and to raise its equity coverage of the key raw material alumina. The work to determine the potential bauxite reserves and possible pursuit of additional reserves in the Kimberly region will start in July. Hydro and UMC will soon begin talks with local authorities and key community stakeholders in Australia. The success of the project will depend on ALUMINIUM · 7-8/2008 ECONOMICS achieving a large and reliable supply of bauxite at an acceptable grade, as well as a correspondingly large and reliable supply of natural gas at viable price. The joint venture is subject to completion of satisfactory due diligence and formal documentation. Once bauxite and energy requirements are generally satisfied, Hydro will contribute 100% of feasibility expenditure with respect to the alumina refinery through to the conclusion of a bankable feasibility study. UMC is a listed Australian mining company with substantial bauxite tenements in the Kimberly region, with activities mainly in diamonds, iron ore and bauxite. In November 2007 Hydro entered into a joint venture with UMC with the intention of recovering bauxite and producing alumina in Kimberley, Western Australia. The agreement gives Hydro a 75% share in the partnership. The first phase of the new agreement should complete current investigations by the end of 2009 within a total cost of NOK40m (US$7.4m). Hydro is paying a large share of the preliminary investigation cost. If this confirms commercially recoverable deposits Hydro will consider options for a mining company and an alumina refinery, which may then result in an investment decision. A possible bauxite and alumina project in Australia is in line with Hydro’s strategy to increase the company’s primary aluminium production and step up its production of alumina. At the beginning of July 2007 Rio Tinto approved a US$1.8bn expansion of its Yarwun alumina refinery in Gladstone in the eastern Australian state of Queensland. The project will more than double the plant’s production capacity from 1,4m tpy to 3.4m tpy of alumina. Work on the expansion will start in the third quarter of 2007 and is expected to take about three years to complete. First shipments from the expansion are expected in the second half of 2010. The refinery draws its feedstock from the Weipa bauxite deposit. In August Bechtel Corporation of San Francisco began work on Rio Tinto’s US$1.8bn expansion of its Yarwun alumina refinery in Gladstone, Queensland. Bechtel is providing engineering, procurement and construction management for the project. The project will include construction of a 160 MW gas-fired cogeneration plant that will improve energy efficiency while reducing greenhouse gas emissions. In August 2007 the government of the Australian state of Queensland granted the status of ‘significant project’ to the 6.5m tpy Aurukun bauxite project being developed by Chalco. The status enables the state government to play a key role in co-ordinating the decision-making process for the project, which involves federal, state and local governments. The approvals process is expected to be complex due to the large number of local, state, and Commonwealth agencies involved. The Indigenous Land Use Agreement inked with aboriginal landowners in May has also been formally registered. Chalco is planning to build a 2.1m tpy alumina refinery as part of the US$1.8bn Aurukun project. It will also construct bauxite loading facilities, including a jetty, wharf and associated port facilities at Boyd Point north of Aurukun to accommodate 70,000 tonnes Panamax vessels. It plans to ship bauxite from the mine to a refinery at either Townsville, Bowen or Gladstone on the east coast of Queensland. EUROPE France: In October 2007 Rio Tinto Alcan inaugurated new facilities Bauxite mining and reafforestation in Western Australia ALUMINIUM · 7-8/2008 27 ECONOMICS for making specialty alumina at its 700,000 tpy alumina refinery in Gardanne, France. Specialty alumina accounts for 80% of the facility’s sales, with smelter grade alumina generating the remainder. The Gardanne plant employs approx. 500 people. The new facilities, which include both grinding and packaging workshops as well as twelve storage silos, will enable Rio Tinto Alcan to meet growing specialty alumina demand for a variety of applications. The new facilities represent just part of the US$29m invested at Gardanne over he past two years. The company has also invested US$7.2m in 2007 in a new process that filters and dewaters bauxite residue and converts it to Bauxaline, a trademark product that can be used for road embankments and sub-grades. Germany: In November 2007 Dubai International Capital (DIC), which is the private equity arm of Dubai Holding, acquired the German specialty alumina producer Almatis. Almatis, which is headquartered in Frankfurt, and has eight manufacturing sites in Germany, the Netherlands, the USA, Japan, China and India. It has plans to increase capacity by 20% to around 750,000 tpy by 2010 and is targeting an aggressive expansion into developing markets such as the Gulf region, India and Brazil. DIC is acquiring Almatis from funds controlled by Rhone Capital and Teachers’ Private Capital, the investment arm of the Ontario Teachers’ Pension Plan. Romania: In December 2006, Romanian aluminium producer Alro announced it will invest US$50m over the next two years in upgrading the alumina refinery at its subsidiary Alum. The investment serves to modernize the main production facilities at Alum, to cut the consumption of materials and energy, to upgrade the thermal power plant and to align the plant to European environment protection standards. The work required a complete shutdown of the plant in 2007. The upgrade will lift capacity at the refinery from 500,000 tpy to 600,000 tpy. Beyond that, Alro aims to increase capacity to 1m tpy by 2010. In October, Netherlands-based aluminium producer Vimetco announced plans to acquire bauxite mines within the next three or four years as part of its wider plans to achieve full vertical integration. Vimetco is currently looking at opportunities in India and Guinea. The company expects to restart its Tulcea (Alum) alumina refinery in Romania by the end of 2008. Production was suspended in 2007 to upgrade and modernize the plant. Russia: On 27 March 2007 Rusal, Sual and Glencore completed their deal to combine their assets and create UC Rusal. The concern combines four bauxite mines, ten alumina refineries, fourteen aluminium smelters and three foil millswith over 100,000 employees in seventeen countries worldwide. The new company has pro forma sales of approx. US$12bn. The group’s production capacity totals approximately 4m tpy of aluminium and 11m tpy of alumina. The company owns extensive, high quality bauxite reserves, and has access to a significant energy base. In May 2007 UC Rusal announced completion of a state feasibility study appraisal for the construction of the Komi Aluminium bauxite and alumina complex in the Komi Republic. Investments will exceed US$1.5bn. The project includes constructing a 1.4m tpy alumina refinery and as well as expanding capacity at the Middle-Timan bauxite mine from 2.6m tpy to 6.4m tpy. The feasibility study was developed by the Russian National Aluminium and Magnesium Institute (VAMI), which is part of UC Rusal. Construction started in June 2007. The refinery will use state-ofthe art Bayer technology. The refinery’s infrastructure is being built at the production site in the Sosnogorsk region. Rusal’s Engineering and Construction Division is carrying out all construction. The proven reserves of the Eurasia Middle-Timan bauxite deposit amount to 260m tonnes. The complex will create more than 10,000 new jobs, and when it starts production at the end of 2009 it will secure more than a 40% increase in Russia’s alumina output. Investment in the infrastructure development in the Komi Republic will reach US$25m. In October UC Rusal announced its aims to lift annual aluminium production capacity to 6m tpy and alumina production to17m tpy by 2013. Ukraine: In September 2007 UC Rusal announced it invested US$158m in the upgrade and expansion of production facilities at the Nikolayev alumina plant in Ukraine: Since Rusal bought the company it has invested more than US$180m. According to investment liabilities, the company should increase alumina output to 1.6m tpy in 2009. N EU Commission opens in-depth investigation into BHP Billiton‘s proposed acquisition of Rio Tinto The European Commission has opened a detailed investigation under the EU Merger Regulation into the proposed acquisition of Rio Tinto by BHP Billiton. Both companies are British-Australian dual-listed companies that mine and market a range of commodities such 28 as iron ore, coal, uranium, aluminium, mineral sands, copper and diamonds, as well as various other base metals and industrial minerals. The Commission’s initial market investigation has indicated that the proposed takeover raises serious doubts as to its compatibility with the Single Market. Concerns arise in particular as re- gards the markets for iron ore, coal, uranium and aluminium and mineral sands, because the proposed takeover could result in higher prices and reduced choice for these companies’ customers. The Commission now has 90 working days, until 11 November 2008, to take a final decision on whether the concentration would ALUMINIUM · 7-8/2008 significantly impede effective competition within the European Economic Area or a substantial part of it. Competition Commissioner Neelie Kroes said: “The commodities produced by BHP Billiton and Rio Tinto are basic inputs for major industrial sectors and are therefore crucial for Europe’s competitiveness. The recent surge in commodity prices has had a serious impact on the industries buying these commodities, their customers, and ultimately all the consumers in Europe and elsewhere in the world. In this very sensitive, context any change making the situation worse could be extremely harmful. Therefore the Commission will pay particular attention to ensure that this takeover does not adversely affect competition in Europe.” The main commodities at stake are iron ore, coal, uranium, aluminium and mineral sands. Iron ore and metallurgical coal are the main inputs used in the production of steel, and the levels of market concentration following this merger would be very high. BHP Billiton and Rio Tinto have substantial interests in a number of iron ore mines and coal operations, mainly in Australia. The Commission’s preliminary investigation found that after the takeover the new entity would in itself hold a significant share in the supply of iron ore and together with its next competitor would control a very large part of iron ore supplies. As regards metallurgical coal, the proposed transaction would reinforce the leading position of BHP Billiton, with smaller competitors far behind. By increasing the new entity’s market power in iron ore and metallurgical coal, there is a serious risk that the planned takeover could have a negative impact on the outcome of price negotiations with steel customers. Furthermore there is a serious risk that the merged entity might have the incentive to reduce the scale of its investment projects or slow down such investment, and so reduce supplies available on the market and increase prices. Uranium is purchased by power companies for the production of electricity in nuclear plants. Concerns were raised during the Commission’s preliminary investigation that the proposed merger, by combining two significant suppliers of uranium, would reduce the choice of alternative suppliers. Concerns were also raised in relation to aluminium, which is used in many applications such as packaging and aeronautics, and in relation to mineral sands, which contain titanium oxide which is used in paint. Rio Tinto and BHP increase prices on iron ore Rio Tinto announced 1 July it had reached agreement with all of its customers in Asia for iron ore deliveries from Hamersley Iron, Robe River and Hope Downs for the contract year commencing 1 April 2008. The new settlements are in line with Hamersley Iron’s Baosteel settlement, which saw lump prices increase by 96.5% and fines prices increase by 79.88%. BHP Billiton too announced early in July it had reached an agreement with China’s Baosteel on the price for iron ore deliveries. BHP enforced lump and fine prices increase by 97 percent.

There is a marked increase in exhibitors from India and other Asian countries as China and Malaysia, and eastern Europe (Poland and Slovenia). With the support of GDA (Association of the aluminium producing and processing industry in Germany) as patron and EAA European Aluminium Association, the fair has developed into a key event in the aluminium world’s calendar. This is borne out by the fact that exhibitors and visitors from all over the world travel to Essen. Every third trade visitor now comes from abroad and altogether people from 100 countries attend the trade fair. More than 17,000 visitors are expected in Essen in 2008. Aluminium has thus developed into a global event and the most important trade fair for the industry. ALUMINIUM · 7-8/2008 SPECIAL Theme pavilions offer optimal industry presence In previous years ALUMINUM has set new standards with special events and focussing on special topics. These include theme pavilions, which offer individual sectors of the industry an ideal platform to present themselves, and visitors to the fair focal points for their visits. Here, some of the exhibitors also have the support of their respective trade associations. One of the most important innovations this year is the Primary Pavilion, which is aimed specifically at suppliers of technologies and plant for primary aluminium production. Together with pavilions for surface treatment, the foundry and welding, this pavilion completes the circle of joint stands with which ALUMINIUM covers all fields of activity from the extraction of the raw materials through to the use of aluminium, including all types of processing. So far, a total of 89 suppliers to the primary industry have registered for the fair, among them Almeq Norway and ECL. The Surface Treatment Pavilion and the Foundry Pavilion were already well accepted by exhibitors at the previous fair. The two joint stands, which are supported by VOA and GDM, have been fully booked for a long time.

N Alu Menziken mit neuer Strangpresse Alu Menziken installs new extrusion press Alu Menziken has a reputation for being a competent partner for highly demanding, customer-specific extruded products in certain branches of industry. The company’s most recent investment at its plant in Reinach is a new extrusion press that was installed in only four months. The press line has been fully operational on a three shift basis since May. The main emphasis is on producing extrusions with high added value. Alu Menziken Alu Menziken ist in ausgewählten Industriesegmenten ein kompetenter Partner für anspruchsvolle, kundenspezifische Strangpressprodukte. Jüngste Investitionsmaßnahme am Standort Reinach ist die neue Strangpresse, die in nur vier Monaten errichtet wurde. Seit Mai produziert die Presslinie bereits im vollen Dreischichtbetrieb. Die Herstellung von Strangpressprodukten mit hoher Wertschöpfung steht dabei im Vordergrund. Die neue Presselinie umfasst ein Lager für Aluminiumstangen bis zu Alu Menziken Werk in Reinach 34 Alu Menziken shop floor in Reinach The new press line includes storage for aluminium rods and bars up to 8 m long, a gas-fired bar oven and a 16 MN press, which has a container suitable for billets up to 750 mm long, with run-out lengths up to 46 m, and includes a travelling saw and a double puller. In addition, the press line incorporates a cooling table about 40 m long and there is full integration of the loaded skips in the in-house logistics system. Over 1,400 die sets were modified mechanically to meet the requirements of the new press line in the modernized production facility in Reinach. The new extrusion press now offers greater flexibility in providing a puffer for production and in transporting and artificially ageing profiles. Its well-thought-out and integrated interface communication system ensures that the production steps between the billet furnace and the saw, the billet manipulator and the loader, as well as the press and the stretcher are fully automated. Cooling, run-out table and stretcher are operated at the press of a button via computer control, too. ALUMINIUM · 7-8/2008 S E ICN II UAML 2 0 0 8 A LP UM – M E S S EAVLOURMS ICNHI A UU M 2008 – FAIR PREVIEW The production programme includes profiles with very complex cross-sections and demanding tolerances: linear guides, pneumatic profiles and tubes. Doubling the run-out length together with a long and powerful cooling unit offers several benefits: sawing at the stop mark (improved output), high press output rates (no restrictions because of the flying saw) and cooling of the entire extrusion length under uniform conditions. The production manager, Bernd Seuren, says, “We are thus predestined to extrude thin-walled and complex cross-sections with tight tolerances.” The Alu Menziken group’s new extrusion plant is one of the most modern and most powerful plants of its type in Europe. N Alu Menziken is an exhibitor at ALUMINIUM 2008 in Essen.

Eine Alternative dazu ist die berührungslose Messung, bei der keinerlei Kräfte auf das Blech ausgeübt werden und die kontinuierlich Messwerte liefert. Hier wird das Blech pneumatisch zu Schwingungen angeregt. Die Amplitude der Schwingung wird mit berührungslosen Wegsensoren von Micro-Epsilon Messtechnik erfasst und daraus die Zugspannung quer über die Blechbreite berechnet. Der wesentliche Vorteil der berührungslosen Messmethode liegt darin, dass keinerlei Beschädigung der Oberfläche auftritt. Außerdem verschleißen die Sensoren nicht, sodass Stillstandszeiten und Ersatzteilkosten drastisch reduziert werden können. Somit steigt sowohl die Verfügbarkeit der Anlage als auch die Qualität der Bleche, die damit höchsten Qualitätsanforderungen gerecht werden. N Micro-Epsilon Die Anforderungen an die Oberflächengüte von gewalzten Blechen wachsen stetig. Ob Stahl- oder Aluminiumbleche für den Automobilbau, die Oberfläche muss makellos sein, um dem Kunden eine hochwertige Optik zu bieten. Daher werden in Walzwerken Messgeräte eingesetzt, die die Planheit des gewalzten Bleches erfassen. Durch die hohen Zugkräfte beim Walzen des Bleches besteht die Gefahr, dass die Zugverteilung über die Blechbreite unterschiedlich ist und sich daher das Blech am Rand wellenförmig aufwölbt. Konventionelle Messgeräte erfassen die Zugspannung über Drucksensoren, die in einer Messwalze eingelassen sind. Durch diese berührende Messmethode entstehen jedoch auf der Blechoberfläche Abdrücke der Drucksensoren, die beim Endprodukt sichtbar werden. Außerdem kann nur einmal pro Umdrehung der Messwalze Non-contact and wear-free measuring principle Compes: study on welding bands On the occasion of the ALUMINIUM 2008 in Essen, Compes, a leading producer of aluminium extrusion dies and tools from Italy will present a study on the problem of surface defects in extruded profiles caused by transversal welding bands. The study, carried out in collaboration with extrusion specialist Pandolfo Alluminio, analyzes the dynamics of formation of welding bands and offers die design solutions that can find a way out to the problem. The case study deals with a profile of a curtain wall, of peculiar industrial interest for the whole extruding field. The research activity has gathered all the existing available analysis tools: FEM simulations, press tests and metallographic analyses. The presentation will be held in two sessions of two hours each on 24 September 2008, in rooms M+N of Essen Exhibition Centre from 10 a.m. to 3 p.m. Compes is an exhibitor at ALUMINIUM 2008 in Essen. Hall 3, Stand K30 www.compes.it The requirements on the surface quality of rolled sheets are continually increasing. Whether steel or aluminium sheet used in the automotive field – the surface must be flawless to offer the customer a high quality visual appearance. Consequently, measurement equipment is employed in rolling mills to acquire the flatness of rolled sheet. Flatness is taken to mean the surface evenness of the sheet in the unstressed state. Due to the high tensile forces when rolling the sheet, there is the risk that the tensile distribution varies over the width of the sheet and that the sheet will distort in a wave shape at the edges. Conventional measurement devices acquire the tensile stress using pressure sensors which are embedded in a measurement roll. However, due to this contacting measurement method, impressions of the pressure sensors appear on the sheet surface and are visible in the end product. Furthermore, only one measurement can be taken per revolution of the measurement roll. An alternative is the non-contacting method which exerts no force on the sheet and supplies continuous measurements. In this case the sheet is pneumatically excited to vibrate. The amplitude of the vibration is acquired with non-contacting displacement sensors from Micro-Epsilon Messtechnik and from it the tensile stress is computed transversely over the width of the sheet. The significant advantage of this non-contacting measurement method is that no damage occurs to the surface. In addition, no wear can occur on the sensors, so drastically reducing downtime and the costs for replacement parts. As a result, this increases plant availability and the quality of the sheet which conforms to current and future quality requirements. N Micro-Epsilon is an exhibitor at ALUMINIUM 2008 in Essen.

Alcoa, for example, chose the Almeq CCM when they set out to build a new smelter in Iceland. One of the biggest advantages the company holds against competing systems, is the machine’s ability to clean different types of crucibles of various sizes. This is partly accomplished by a stationary milling head and a hori- zontal displacement of the crucible. The customers most gained by this feature are smelters that have gone through numerous expansions and operate with two, three or more types of crucibles. Having one machine to clean them all is a big money saver. Using up-to-date components, the entire cleaning process is controlled by a PLC and all data can be recorded for logistic control of all crucibles in a smelter. With its electric cathode preheater Almeq offers another innovative product. Before cathodes blocks are assembled into electrolysis pots, the steel conductor bars must be sealed into them, and then heated to ensure adequate electrical conductivity. Compared to external gas or oil burners traditionally used for this preheating, electric resistance heating from within is safe, clean, and reliable. Experience in several smelters proves that this automated system is amortised by the fuel, operator and other costs it saves. N Almeq is an exhibitor at ALUMINIUM 2008 in Essen. Hall 2, Stand C30/01 www.almeq.com OFFICIAL MEDIA PARTNER Vilmill optimiert das Fräsen Die Haftschicht erlaubt den Einsatz verschiedener Werkstoffe Alle Ansätze, etwa mit Papieren den Reibwiderstand des Werkstücks zum Arbeitstisch zu erhöhen oder mit Hilfe eines Haftsprays das Werkstück zu fixieren, sind in der Praxis zwar weit verbreitet; im Betriebsalltag sind diese Hilfsmittel jedoch oft mit Problemen behaftet und stellen allenfalls nur eine Teillösung dar. Aufgrund dieser Thematik ergeben sich noch immer nur eingeschränkte Vorschubgeschwindigkeiten beim Fräsvorgang mit teils inakzeptablen Ausschussraten oder zusätzlichen Haltestegen, die eine Nacharbeit erfordern. Von der technischen Seite ist 42 Freudenberg Bei der Material abtragenden Bearbeitung von dünnen, eher leichten Werkstücken wie Aluminium sind die Bearbeitungskräfte und damit die Vorschubgeschwindigkeiten beim Fräsen mit hohen Drehzahlen maßgeblich von den Möglichkeiten des Fixierens der Teile beim Durchtrennen der Verbindung zum Restgitter abhängig. Die Probleme in der Fertigung steigen, wenn es darum geht, kleine Bauteile herzustellen und die übliche Vakuumtechnik oft keine genügend große Fläche vorfindet, um das Teil während des Trennvorgangs zu halten. die Kundenforderung nach filigranen Teilen limitiert umsetzbar und führt oft zur Enttäuschung wegen mangelnder Wirtschaftlichkeit oder wegen technischer Nichtmachbarkeit. Die Entwicklungsarbeiten von Freudenberg führten zu neuen Ansätzen in der Spanntechnologie.

Vielfältige Praxistests mit diesem neuen patentierten Verfahren unter Verwendung von Vilmill zeigen bemerkenswerte Ergebnisse: • Die Vorschubgeschwindigkeit von entsprechenden leistungsfähigen Maschinen kann auch bei filigranen Teilen um bis zu 100 Prozent gesteigert werden. Limitierender Faktor beim Fräsen ist somit die Mechanik der Fräsmaschine und nicht mehr die mangelhafte Fixierung des Werkstücks beim Verarbeiten. • Durch die Fixierung ist eine höhere Präzision und Maßgenauigkeit der gefrästen Teile möglich, sodass die Notwendigkeit zur Nacharbeit sinkt und eine höhere Qualität erreicht wird. • Bei den Werkstücken handelt es sich oft um teure Materialien. Durch die Fixierung lassen sich die Zuschnittteile enger positionieren, wo- Das Substrat dient als Unterlage Mit Vilmill wurde ein Substrat entwickelt, das als Unterlage zwischen Werkstück und Frästisch zum Einsatz kommt. Das Substrat besitzt eine eingebaute Haftschicht, die erst beim Fräsvorgang selbst aktiviert wird. Bei Anwendung der Vakuumsaugtechnik dient es mit seiner ausgewählten Faserstruktur als Diffusor und erhöht die Vakuumeffizienz. Beide Effekte führen zu einer deutlich verbesserten reversiblen Fixierung der Werkstücke und der gefrästen Reststücke während des Fräsvorganges bis zur Entnahme. Vilmill ist mit seiner speziellen Allround-Haftschicht so ausgelegt, dass eine Vielzahl von verschiedensten Werkstoffen (Aluminium, Messing, Kupfer, Verbundwerkstoffe, Kunststoffe, auch Glas- und Kohlefaserkunststoffe) im Prozess verwendet werden können. Das Substrat ist ökologisch unbedenklich und kann unter Beachtung der örtlichen An- durch es zu einer verbesserten Materialausnutzung kommt und damit zu einer Kostenreduzierung. • Auch kleine Teile bleiben in der speziellen Haftschicht gut eingebettet, sodass die Teile sicher gehalten werden und die Prozesssicherheit eine automatische Fertigung zulässt. Vilmill als Unterlage in der Maschine schützt zudem den Frästisch und dient ideal zum Abtransport der Teile vom Bearbeitungstisch. Vilmill ist erhältlich in Rollenform und mit verarbeitungsgerechten Materialbreiten. Es ist auch in älteren Fräsmaschinen weltweit einsetzbar.

Darauf muss auch die Fertigung eingestellt sein: zum Beispiel durch eine wirksame Absaugung bei der Schleifbearbeitung. Die ALUMINIUM 2008 bietet der Ruwac Industrie-Sauger GmbH daher das passende Forum, um der Metall verarbeitenden Industrie verschiedene Möglichkeiten der Absaugung von Aluminiumstäuben vorzustellen. Grundlage für die Anwendung dieser Anlagen ist die BG-Richtlinie 109, die Hinweise zur „Vermeidung der Gefahren von Staubexplosionen beim Schleifen, Bürsten und Polieren von Aluminium und seinen Legierungen“ gibt. Die Richtlinie nennt verschie- 44 dene Verfahren zur Beseitigung von Aluminiumstaub. Nach Erfahrung von Ruwac ist in den meisten Fällen ein Nassabscheider die sicherheitstechnisch und wirtschaftlich beste Lösung. Bei der von Ruwac entwickelten Technologie wird das Sauggut zunächst durch eine Flüssigkeit geleitet. Auf diese Weise werden eingesaugte Zündquellen unschädlich gemacht, heiße Gase werden gekühlt und Explosivstoffstäube neutralisiert. Ein nachgeschaltetes Filtersystem hält die Verunreinigungen zurück. Alternativ kann auch eine Funkenfalle zum Einsatz kommen, die rein mechanisch arbeitet und den Zündquellen ihre Zündenergie nimmt. Aufgrund der modularen Bauwei- se der Ruwac-Sauger können beide Verfahren (Nassabscheidung und Funkenfalle) als Zusatzmodul auf kompaktem Bauraum in konventionelle ATEX-gerechte Ex-Sauger integriert werden.

Together with Fraunhofer IFAM, Bremen, Plasmatreat has developed the ‘PlasmaPlus’ technology, which, for the first time, enables material surfaces to be given a nano-fine coating at atmospheric pressure. As Plasmatreat emphasizes, the technology is highly efficient economically because in contrast to the low-pressure process it does not require a vacuum chamber. At TRW Automotive, a manufacturer of vehicle security systems, motor/ pump housings for steering units are now being coated with this technology. Coating is carried out in-line and guarantees a high level of protection against the ingress of moisture. Even microscopically small leaks resulting from corrosion can lead to short circuiting and to loss of the power steering. Today, the pretreatment of aluminium profiles prior to lamination usually necessitates several production steps: from cleaning to mechanical pretreatment. In decorative applications, profiles are laminated with cover foils which give products the necessary appearance and surface feel. High demands are placed on the foil–metal joint. The polyurethane and epoxy resin adhesives used need an optimally pretreated metal surface in order to guarantee good adhesion. Openair plasma technology enables not only continuous pretreatment in a single process step but also meets the highest possible demands with respect to the extremely fine cleaning of the metal.

Rieth, Meerbusch In all these fields of activity SMS Meer has a store of experience accumulated over years from the construction of numerous plants. By continual innovation the company has developed into the world market leader for most of its products. This also applies in the aluminium sector, in which it is successfully active as a competent partner for the planning, engineering, production, assembly, commissioning and servicing of equipment for melting through to semis production. In this, the company’s aim is always to supply the customer with a plant that gives him competitive advantages. In focus: energy efficiency and environmental friendliness Hertwich Engineering GmbH in Braunau, Austria, which has been part of SMS Meer since 2000, has consistently extended its leading position in the sector of aluminium melting and casting equipment. Its particular experience and technological solutions for the construction of environmentally friendly and energy-efficient plants have made the company one of the leading suppliers of modern melting and casthouse equipment. Especially in the melting of contaminated scarp, increasingly strict environmental demands have to be met. For this, Hertwich uses static, multi-chamber melt furnaces with a pre-heat shaft for uniform heating through of the scrap. The energy efficiency and environment friendliness of Hertwich units 50 Hertwich Engineering Within the SMS Group, one of the world’s leading metallurgical plant engineering concerns, the SMS Meer is mainly known for tube and section rolling plants and forging aggregates. Besides such equipment directed at the needs of the steel industry, the company supplies a wide range of highly specialized equipment for many processing steps in the aluminium and copper industries. Multi-chamber melt furnace at Logan Aluminum, USA is demonstrated inter alia by the recycling furnace supplied for the aluminium smelter at Hydro Aluminium Neuss in 2007. This is designed for a melting output of 50,000 tpy and deals with the process scrap generated by the Hydro cold-rolling plant. The combustion of coatings and lacquers is used to supply energy for the furnace. A multi-chamber melt furnace recently commissioned at Logan Aluminum in the USA for 65,000 tpy of molten aluminium produced from both clean and contaminated scarp (such as compacted scrap, litho plates, used beverage cans, etc.) represents the latest state of the art, in terms of minimal oxidation losses, the lowest emissions and the least possible energy consumption. These characteristics are achieved thanks to an integrated process developed by Hertwich, in which the scrap heating and melting take place in a combined way. A complete remelting plant for the recycling of clean and contaminated extrusion scrap and subsequent casting of 12,000 tpy of logs will start operating in the autumn of 2008 at Gulf Star Alloys WLL in Bahrain. In an automated and continuous production process, this contract includes a multi-chamber melt and casting furnace with an automatic charging system and a horizontal continuous casting unit with a flying saw, a continuousthroughput homogenizing unit and a saw for billets. The combustion of organic contaminants during the melting serves to improve energy recuperation. Thus, the furnace is characterized by substantially reduced energy consumption and much lower melt loss. The continuous homogenization unit for logs, of which more than 90 have been supplied since the first one in 1980, has since become one of Hertwich’s most successful products. Just recently the company received an order from general contractor Fata in Italy for one of the most powerful continuous homogenising units to go to the new Qatalum Aluminium Smelter Project in Qatar. Hertwich has recently received important contracts for furnaces for the melting of aluminium swarf, among others from Otto Fuchs and Trimet Aluminium in Germany. For this particular application, which is a distinct growth area because of the increasingly large number of machined aluminium components, the company has developed a process substantially better than the methods used until now. Accordingly, large processing and forging plants can now melt the swarf they generate on the spot. ALUMINIUM · 7-8/2008 TECHNOLOGY Photos: SMS Meer The swarf is conveyed pneumatically from the machining stations to the swarf dryer and heated by an intense hot gas stream to about 400°C to remove moisture and contaminants. It is then fed continuously into the melt bath and is already melted less than a quarter of an hour after it has been produced. Worth stressing is the high metal yield of 98.5 percent of the dry charge weight. At 600 kWh/t including drying and degassing, energy costs are low. Large extrusion presses for high-tech sections Large extrusion presses account for a high proportion of the 110 ‘Schloemann Extrusion Presses’ built during the past eight years. Under that trade name SMS Meer offers its extensive range of extrusion presses and in this, also includes the tradition of brands taken over earlier such as Eumuco, Innse and Sutton. In 2008 alone the company is building 28 new presses. Besides the short-stroke, front-loading presses which have by now become standard, these also include special machines such as indirect presses or tube presses. The latter are used not only for aluminium, but also for heavy metals and for high-alloy stainless steel tubes, for example at the two Chinese steel plants Taiyuan 55-MN strand and tube press with dummy block / die manipulator and intensive cooling, at Shandong Nanshan Alu, China Iron & Steel and Bao Steel, each of which has a unit with extrusion load 60 MN. These produce tubes of corrosion-resistant or high-temperatureresistant stainless steels or nickelbased alloys, which cannot be made using traditional tube-making methods. The application range of these tubes includes among others chemical plant construction, power station technology and offshore uses. In the aluminium sector tube presses are mainly used where the use of bridgetype dies, for example for high-alloy materials that are difficult to extrude or for safety-relevant components, is not possible. Overall, a study of SMS Meer’s references shows that the greatest proportion of presses have extrusion loads of 35 to 82 MN. The company explains this in that its modern, robust press design is particularly suitable for the production of high-tech sections, which mainly demand higher extrusion loads in order to be able to apply a high specific extrusion pressure. Such products are heavy industrial sections, thin-walled high-strength sections for the automobile and aviation industry, and large sections for example for rail vehicle engineering. Interview with Joachim Schönbeck, Member of the Management Board of SMS GmbH and President of SMS Meer GmbH proportion of orders from the aluminium industry for SMS Meer? Schönbeck: For the increases you speak of, we have to thank not only our products for the tube and long products rolling plants in the steel industry, but also, and gratifyingly, our customers in the aluminium industry. In recent years that branch has developed so well that, having regards to year-on-year fluctuations, it now accounts for between 15 and 20% of SMS Meer’s business volume. ALUMINIUM: What are SMS Meer’s products for the aluminium sector? Schönbeck: The SMS Group’s products are used in almost every stage of aluminium production. Besides the rolling mills and strip treatment lines © Competitive advantages thanks to superior equipment and services Joachim Schönbeck: “Using our equipment brings our customers competitive advantages.” ALUMINIUM · 7-8/2008 ALUMINIUM: Mr Schönbeck, for 2007 the annual report of the SMS group showed an impressive increase of order intakes by 59% compared with the previous year, to 5.14 billion euros. 2007 saw an increase by a similar percentage in order intakes by SMS Meer, to 1.35 billion euros. What is the continued on page 53 51 TECHNOLOGY from SMS Demag, SMS Meer supplies the casting and melting equipment manufactured by Hertwich Engineering, the extrusion plants that we offer under the trade mark ‘Schloemann’, and ingot scalping machines under the brand ‘Knoevenagel’; last but not least, we provide heavy stretching machines for aluminium plates. This, by the way, makes us the only supplier worldwide that offers the aluminium industry so wide a product range. ALUMINIUM: What are the reasons for the impressive growth of your order intakes? Schönbeck: One reason stems from the development we are currently experiencing in the raw materials and energy markets, which have led to a special trade situation of historical dimensions. The strong demand from developing countries such as China has created worldwide shortages of important commodities. As equipment suppliers for the investment goods industry, we are deriving particular benefit from this situation – and this applies both to our aluminium and to our steel branches. ALUMINIUM: Are there any further success factors? Schönbeck: We are market leaders for most of our products, and in the case of aluminium actually all of them. We justify our claim to leadership by virtue of outstanding plant technology. Our aim is to provide our customers with competitive advantages due to superior machines and services, and we are committed not only to maintain the technical superiority we have established, but also to develop new products and thereby set technological trends. ALUMINIUM: Can you give us any examples from the aluminium sector? Schönbeck: One example is the frontloading press. Just ten years ago we established it on the market, and it has now become the industrial standard worldwide. In the fields of extrusion I can also point to our development jointly with the University of Dortmund, for the production of curved extrusions. For example in the production of components for the automobile industry, compared with conventional production methods this saves a complete process step. Here, we expect a breakthrough into more general industrial application in the foreseeable future. ALUMINIUM: And how does this apply to your other product sectors? Schönbeck: We regard our market success in the sector of melting and casthouse equipment as mainly the result of our development efforts aimed at supplying plant that improves metal yield and at the same time making a contribution towards protecting the environment. Here, we have reached a position that sets an example. ALUMINIUM: How far has the integration of SMS Eumuco progressed? Schönbeck: The organizational and geographical integration of SMS Eumuco was completed at the beginning of 2008 with the relocation from Leverkusen to Mönchengladbach. The successful Eumuco products retain their identity and thanks to our decentralized organization principle proximity to the market is fully preserved. The name Eumuco survives in ‘Eumuco-Hasenclever Die-forging Machines’. Thus, under than trade name Eumuco-Hasenclever we offer our wedge-type, eccentric and cranktype presses, with which in any case important aluminium components such as automobile wheels and chassis components are produced. ALUMINIUM: SMS Eumuco was previously your product sector for extrusion. Has something changed there? Schönbeck: Extrusion presses are still a particularly important product for SMS Meer. As is known, over the years we have acquired a number of different trade names by various mergers, such as ‘Schloemann’, ‘Demag’, ‘Eumuco’, ‘Innse’ and ‘Sutton’. SMS Meer is continuing the tradition of those names under the umbrella trade name ‘Schloemann Extrusion Presses’. ALUMINIUM: Where are your most important markets for aluminium plant at present? Schönbeck: Growth markets such as China and Russia are of course very fertile for our products, especially since the customers there know and esteem the reliability of our equipment. The over-proportional growth of aluminium production and further processing in the Near East, resulting from energy cost factors, provides us with concrete potential for consolidating and extending our already strong position in that market. ALUMINIUM: How important are the traditional markets in the European and American industrial countries for you? Schönbeck: For some of our aluminium products very important indeed. There I am thinking particularly of the melting equipment manufactured by Hertwich, which is designed to satisfy current environmental demands. But there is also lively demand in those markets for our high-tech solutions in the extrusion sector. ALUMINIUM: SMS Meer builds equipment for many metallurgical applications. From that perspective how do you view the future development of the aluminium market that you serve? Schönbeck: In a direct product comparison with steel aluminium traditionally has the advantage of low weight and corrosion resistance. Against that is the high energy intensity for its extraction. In our estimation that cost disadvantage is being reduced by the overheated steel trade, to an increasing extent in aluminium’s favour. Add to this the fact that in the application of aluminium as well, development is moving for example towards lightweight construction in industry. Overall, therefore, we expect to see further positive development of the aluminium market and thus of our products too, since the application potential of aluminium is far from being exhausted. ALUMINIUM: And how do you see the regional aluminium markets developing? Schönbeck: We are assuming that the classical markets will essentially remain active. However, there is an increasingly strong trend for aluminium smelters and consequently also for downstream processing activities to be relocated to regions where energy can be produced in large amounts at reasonable cost. ALUMINIUM: Mr Schönbeck, many thanks for this discussion. N 52 ALUMINIUM · 7-8/2008 TECHNOLOGY Continued from page 51 Besides the large presses SMS Meer has had numerous orders for frontloading presses of medium size, which have developed as standard for light metal sections. The sizes of 22/24 MN or 25/27 MN typical for 8-inch billets secure for extrusion companies access to the market of sections for building applications. A look at the customer structure, however, confirms that here, too, is a trend towards more sophisticated sections, which the SMS front-loading presses can produce in outstanding quality. This is attributed above all to the high rigidity achieved by the compact structure of the press, the short idle times because of short travel paths, and high productivity thanks to the large billet lengths (for example 1300 mm for 8-inch billets) that can be used. The regional distribution of customers for Schloemann extrusion presses is also striking. Besides developing markets such as China with 22 new Schloemann presses (of which 14 have gone to Shandong Nanshan alone) and countries in the Near East, in recent years the company has also supplied presses to markets in the classical industrial countries, which have recently been regarded as rather slow to invest This, too, reflects the ‘high-end’ orientation of SMS Meer in the context of high-grade, large presses with which the investors are safeguarding the future of their plants. Although the company has recently sold many individual presses, one of its strengths is the supply of complete plants, for which the firm acts Automatic eccentric press ALUMINIUM · 7-8/2008 as equipment supplier and if necessary also undertakes the financing of the project. Besides the mechanical equipment, which besides the extrusion press also features special structures for cooling and for pullers, one of the company’s strengths lies in the field of process control. These products developed by SMS Meer follow all the process steps of EWK 2200 x 7200 ingot scalper the plant from extrusion billet optimization up to autocost of subsequent machining. In this matic stacking of the finished sections, connection the choice of the forming with the aim of treating the product aggregate is very important since this carefully and minimising scrap.

An uct range supplement the hot- and essential criterion is the cold-rolling plants for aluminium cost of die-forged comstrips and plates established by its ponents which, besides sister company SMS Demag, namely the cost of the material, ingot scalpers and plate stretchers. the die, the machines and The ingot scalpers supplied unlabour, also includes the der the brand ‘Knoevenagel’ are © 53 TECHNOLOGY Plate stretcher with a stretching force of 70 MN mainly scalpers used to machine away contamination and oxidation in the outer shell area of cast ingots before they are homogenized and hot-rolled. This takes place at throughput rates of about 450,000 tpy in two steps, the ingots being rotated through 180° between the two machining passes; moreover, double-sided scalpers are also used. The ingot scalpers are equipped with a horizontal milling head for the main surfaces and two lateral milling heads for the side surfaces of the rolling ingots. SMS Meer supplies not only the actual scalper, but also all the peripheral equipment such as transport roller tracks, the drum rotator and the swarf extraction system with swarf crusher and swarf removal back to the casthouse. The product range is amplified further by billet saws and handling, welding and brushing equipment for plating bars. Depending on the design, ingot scalpers can reach outputs of 100,000 to more than 800,000 tonnes per year. In recent years business relating to new plants has been very lively thanks to the many new hot-rolling plants built most of all in China. On the other hand SMS Meer continually receives modernization orders in which existing plants are refitted for higher throughputs or larger ingot diameters. An example is the Knoevenagel ingot scalper supplied to Alcoa in Amorebieta, Spain, where a production increase of around 15 percent was achieved. Ingot scalpers by SMS Meer are made for ingot lengths up to 10 m, widths up to 3.2 m and thicknesses up to 750 mm. Ingot weights up to 54 40 tonnes and a throughput performance in single-side scalping of up to 11 ingots per hour are further striking statistics. Also to be mentioned is the continuous dimensional checking of the ingots by laser. The persisting boom in the aviation branch is also leading to growing production of aluminium plates in the traditional manufacturing plants and in new plants at smaller businesses in the industrialized countries. The relocation of component production to resulting lack of flatness of the plates. To stretch elastically aluminium plates with maximum dimensions of 4 m width, 250 mm thickness and 36 m length, SMS Meer builds stretchers with a stretching force of up to 130 MN. This demands exceptionally powerful and robust stretching aggregates, that can only be produced by a heavy-engineering concern such as SMS Meer. Plate stretchers are impressive for their weight alone: for example, in a 70-MN stretcher each of the two clamping heads that grip the plates at their ends weighs around 250 tonnes. This is a challenge, not only for the mechanical workshops but also for the transport logistics to the place where the machine is to be set up. Since the beginning of the boom in plate production a few years ago, SMS Meer has built and commissioned 5 new plate stretchers for plants in Europe, the USA and Russia. Indicative of the future of stretchers is the demand for ever-larger specific stretching forces, which will call for new production methods and, having re- Components for large machines being machined in the newly set up heavy-load shed countries such as China has also led to the creation or planning of more production sites for plates. For SMS Meer this means that lively demand for plate stretchers is likely to continue. These very large aggregates from the ‘hydraulic presses’ sector are used to remove the non-uniform stress distributions produced during the rolling process by means of a stretching process, and thereby to eliminate the gard to transport, a multi-component structure of the clamping heads.

Papadopoulos, Denkendorf; R. Spangenberg, Weißenburg Im Rahmen eines umfassenden Modernisierungsprogramms haben die Hermann Gutmann Werke im bayerischen Weißenburg den Profiltransport im Presswerk automatisiert. Dadurch konnte die Produktivität des Werkes deutlich gesteigert werden. Wenn auch die nachgelagerten Produktionsstufen in dieses System einbezogen sind, wird Gutmann zu den leistungsstärksten europäischen Profilanbietern gehören. 56 On the way to joining the extrusion plant elite G. Papadopoulos, Denkendorf; R. Spangenberg, Weißenburg As part of a comprehensive modernization programme Hermann Gutmann Werke, Germany, has automated the transport of sections in the extrusion plant. This has considerably increased the productivity of the plant. When the downstream production steps have also been incorporated in this system, Gutmann will be one of the most efficient European section suppliers. Founded some seventy years ago as a light-metal wire factory in Weißenburg, then in France, Gutmann has since developed to become a company group active worldwide, with more than 1,200 employees. At a total of four locations high-grade aluminium products are produced, which are used above all in the building branch, the automobile industry and for mechanical and electrical engineering. The focus of the company group’s product range is nowadays on extruded aluminium sections: system Fotos: Herrmann+Hieber Vor sieben Jahrzehnten als Leichtmetall-Drahtwerk im fränkischen Weißenburg gegründet, hat sich Gutmann zu einer weltweit agierenden Unternehmensgruppe mit über 1.200 Mitarbeitern entwickelt. An insgesamt vier Standorten werden hochwertige Aluminiumprodukte hergestellt, die vor allem in der Baubranche, in der Automobilindustrie, im Maschinenbau sowie in der Elektrotechnik eingesetzt werden. Schwerpunkt im Produktportfolio der Unternehmensgruppe sind heute AluminiumStrangpressprofile: Systemprofile für moderne Fenster-, Türen- und Fassadensysteme sowie auch Industrieprofile für hochwertige Anwendungen der unterschiedlichsten Art. Ein markanter Meilenstein in der Entwicklung des Unternehmens, das im vorigen Jahr sein 70-jähriges Firmenjubiläum feiern konnte, war das Jahr 2002. In diesem Jahr beendete der Einstieg der griechischen ALCO Hellas AG, die sich mit 51 Prozent an Gutmann beteiligte, die schwierige Unternehmensphase nach dem Tod des Firmengründers Hermann Gutmann im Jahre 1987. Die Unternehmensgruppe ALCO Hellas, die in Griechenland zwei Presswerke betreibt und dort an drei Standorten produziert, bescherte Gutmann und eine verbreiterte Kapitalbasis, eine straffe Führung und auch eine erfolgsorientierte Unternehmensstrategie. Hermann Gutmann Werke sections for modern window, door and façade systems and also industrial sections for high-grade applications of the most varied kinds. An important milestone in the development of the company, which last year celebrated its 70th anniversary, was the year 2002. In that year the accession of Greece’s ALCO Hellas AG, which acquired a 51% share in Gutmann, put an end to the difficult phase the company had been through after the death of its founder Hermann Gutmann in 1987. The ALCO Hellas group, which operates two extrusion plants in Greece and produces at three locations there, provided Gutmann with a broader capital basis which had a positive effect on the group’s future development. Extension of extrusion business at Gutmann This strategy aims to achieve a consistent extension of extrusion business, above all in two directions: on the one hand, the company can expand by virtue of takeovers. In 2004 Gutmann took over the extrusion activities of the renowned façade manufacturer Gartner in Gundelfingen and incorporated them as Eindrücke vom Strangpresswerk der Gutmann Werke: … Gartner ExtruImpressions of the Hermann Gutmann extrusion plant: … ALUMINIUM · 7-8/2008 TECHNOLOGY sion GmbH. The next step, in April 2007, was to take over NordAlu Wemal GmbH in Schleswig-Holstein, which is now run as NordAlu GmbH as part of the Gutmann group. Thus, Gutmann is now producing extrusions at three different locations. In addition, however, the Gutmann extrusion plant in Weißenburg has been modernized and extended with considerable investments. In retrospect it can be said that the plant has moved on, from a condition of moderate productivity in the early 1990s, to become a profitable operation now after several extension steps. When this extension of the plant is completed in a few years, Gutmann will be among the elite group of extrusion plants in Germany. In the new planning of the operating sequences Gutmann worked closely together with the logistics specialists Herrmann+Hieber in Denkendorf. This collaboration goes back to 1994 when, in a first project, the transport of racks between press P5 and the heat treatment furnace was automated in the form of an island system. In 2000, in the next step three automated packing positions for the sections were planned and created. Now a third project has been successfully completed, in which the storage and ageing have been completely reorganized and automated along with the section transport between the stacker and the packing station. With the completion of this extension stage a technical standard has now been achieved at the plant in Weißenburg which is clearly a close approach to the operating procedure of the final condition aspired to. Installation review and logistical concept In the most recent modernization project the two presses P3 and P4 arranged in parallel, with the heat treatment, the store and the packing, are being combined in a closed, automated system. Within the system, beginning from the section stackers the material is automatically transported through the plant in racks. In the planning, it was decisively important to design the capaci- © ALUMINIUM · 7-8/2008 Ausbau des Strangpressgeschäftes bei Gutmann Aufstellungsübersicht und Logistikkonzept Diese Strategie zielt auf einen konsequenten Ausbau des Strangpressgeschäftes, und zwar in zwei Richtungen. Auf der einen Seite konnte das Unternehmen durch Übernahmen expandieren. 2004 übernahm Gutmann die Strangpressaktivitäten des renommierten Fassadenherstellers Gartner in Gundelfingen und überführte diese in die Gartner Extrusion GmbH. Im April 2007 gelang im weiteren Schritt die Übernahme der schleswig-holsteinischen NordAlu Wernal GmbH, die jetzt im Rahmen der Gutmann-Gruppe als NordAlu GmbH geführt wird. Gutmann produziert somit jetzt an drei Standorten Profile. Darüber hinaus wurde das Gutmann-Presswerk in Weißenburg mit erheblichen Investitionen modernisiert und ausgebaut. Im Rückblick kann man sagen, dass das Werk aus einem Zustand mäßiger Produktivität zu Beginn der 1990er Jahre in mehreren Ausbaustufen zu einem profitablen Betrieb geführt wurde. Wenn dieser Ausbau des Werkes in den kommenden Jahren abgeschlossen sein wird, dann dürfte Gutmann zur Spitzengruppe der deutschen Presswerke zählen. Bei der Neuplanung der Betriebsabläufe arbeitet Gutmann eng mit dem Denkendorfer Logistik-Spezialisten Herrmann+Hieber zusammen. Diese Kooperation reicht bis in das Jahr 1994 zurück; damals wurde in einem ersten Projekt der Korbtransport zwischen der Presse P5 und dem Wärmebehandlungsofen in Form einer Insellösung automatisiert. Im Jahre 2000 wurden im nächsten Schritt drei automatisierte Packplätze für die Profile geplant und realisiert. Jetzt wurde ein drittes Projekt erfolgreich abgeschlossen, mit dem Lagerung und Alterung komplett neu organisiert und zusammen mit dem Profiltransport zwischen Stapeleinrichtung und Verpackung automatisiert wurden. Mit dem Abschluss dieser Ausbaustufe wurde jetzt im Werk Weißenburg ein technischer Stand erreicht, der den Betriebsablauf dem angestrebten Endzustand deutlich annähert. Mit dem jüngsten Modernisierungsprojekt wurden die beiden parallel angeordneten Pressen P3 und P4 mit der Wärmebehandlung, dem Lager und der Verpackung zu einem in sich geschlossenen, automatisierten System verbunden. Innerhalb dieses Systems wird das Material, bei den Profilstaplern beginnend, in Körben automatisch durch das Werk transportiert. Bei der Planung kam es entscheidend darauf an, die Kapazitäten und Anordnung von Öfen, Lagerflächen und Transporten so zu gestalten, dass – unter den gegebenen Platzverhältnissen – ein reibungsloser Automatikbetrieb erreicht wird. Dabei war nicht nur das wirtschaftliche Optimum anzustreben, es mussten darüber hinaus auch die weiteren Ausbaumög- … nach umfassender Modernisierung … … after omprehensive modernization … lichkeiten des Systems, mit denen zukünftig auch die dritte Presse des Werkes und die Oberflächenbehandlung in den automatisierten Ablauf integriert werden sollen, berücksichtigt werden. In der Planungsphase entschied man sich, die Kranbahn des Automatikkranes quer zur Pressrichtung anzuordnen. Mit dieser Aufstellungsvariante gewinnt der Krantransport eine zusätzliche Verteilerfunktion, indem die Profilkörbe direkt den Lagerflächen, den Auslagerungsöfen und den Packplätzen zugeordnet werden können. Die alternative Lösung mit mehreren Transportkrananlagen in Pressrichtung wurde verworfen, weil sie letztlich wirtschaftlich nicht optimal ist. Bei dieser Anordnung hätten die Krantransporte lediglich das Lager bedienen können. © 57 TECHNOLOGIE In das System eingeschleust werden die gefüllten Profilkörbe auf zwei Rollenbahnen, auf denen die Körbe von den Stapeleinrichtungen der beiden Pressenlinien bis unter die Kranbahn transportiert werden. Die Zuführbahnen für volle Körbe sind ebenerdig angeordnet, für die Rückführung der Leerkörbe ist jeweils ein zweiter Korbtransport in der Ebene darüber vorgesehen. Der Bereich unter der Kranbahn ist in Lagerflächen und in Wärmebehandlung unterteilt. Für die Wärmebehandlung wurden zwei in die Jahre gekommenen Alterungsöfen entfernt. Dafür wurden unter der Kranbahn insgesamt fünf neue Top-Loader-Öfen der Firma IUT angeordnet. Gewählt wurde diese Lösung aufgrund der beengten Platzverhältnisse vor Ort. Die Öfen besitzen abnehmbare Deckel und werden über den Kran von oben beund entschickt. Der Kran hebt dazu den Ofendeckel an und legt diesen auf einem anderen Ofen ab. Er entnimmt die wärmebehandelten Profilkörbe und setzt danach wieder neue Körbe ein. Insgesamt fasst jeder Ofen zwei Fünffach-Korbstapel nebeneinander, so dass HGW auf für die Zukunft entsprechende Alterungskapazitäten vorweisen kann. Der Hauptlagerbereich des Systems wurde unmittelbar unter der Krananlage angeordnet. Um genügend Lagerkapazität zu gewinnen, ist dieser Bereich so konzipiert, dass jeweils zwei Korbstapel hintereinander angeordnet sind. Auch die Andienung von leeren Schrottkörben und deren Abtransport gehören zur Aufgabe des automatischen Systems. Eine Krananlage der Superlative Bei der Automatisierung des Korbtransportes im Strangpresswerk ist der Automatikkran ein unverzichtbares Transportmittel. Mit dem Krantransport sind Korbbewegungen möglich, die mit Hilfe von Rollenbahnen nur sehr umständlich zu realisieren wären. In den meisten Fällen reichte dafür auch die verfügbare Grundfläche nicht aus. Diese Tatsache hat dazu geführt, dass die speziellen Anforderungen an den Korbtransport per Automatik- 58 kran stetig größer geworden sind.

Bei geöffnetem Ofen ist der Kran praktisch durch die Ofentemperatur beaufschlagt. Es musste deshalb für jedes Konstruktionsdetail geprüft werden, ob es dieser Temperaturbelastung gewachsen ist. Autonome Steuerung des Automatikbetriebes Die Investition in eine Automatisierung des Korbtransports rechnet sich auf mehrfache Weise. Einmal lassen sich Transportschäden, die bei dem herkömmlichen Transport mit Flurförderern einen beachtlichen Umfang besitzen, nahezu vollständig vermeiden. Hinzu kommt in aller Regel die größere Produktivität der Strangpresslinien, die auf den störungsfreien Automatikbetrieb zurückzuführen ist. Dieser Betrieb wird zudem mit reduziertem Aufwand an Personal und Transportmitteln erreicht. Um die komplexen Aufgabenstellungen im automatisierten Ablauf bewältigen zu können, wird die Anlage von einem Transportleitsystem gesteuert, das seinerseits mit dem Prozessleitsystem des Presswerkes verbunden ist. Vom Prozessleitsystem werden dem Transportleitsystem lediglich die Auftragsdaten inklusive der abzuarbeitenden Arbeitschritte mitgeteilt. Die sinnvolle Abwicklung aller erforderlichen Transportbewegungen steuert das Transportleitsystem selbst. Weiterhin ist es Aufgabe des Transportleitsystems, für die optimale Auslastung der Alterungsöfen zu sorgen. Lediglich mit der Vorgabe des Ofenprogramms werden sämtliche Abläufe an den Alterungsöfen (wie Zwischenlagerungen, Batchbildung vor, im und nach dem Ofen, Ofenprogrammwahl, Ofenstart, Manipulation der Ofendeckel, Qualitätsprüfung nach dem Altern) optimiert ausgeführt. Zur Qualitätssicherung werden zusätzlich die ermittelten Temperaturverläufe einer jeden Charge zu Dokumentationszwecken dem Qualitätsmanagement des Presswerkes übergeben. In der folgenden Verpackung sorgt das System mit intelligenten 60 Lagerstrategien und reibungslosem, kontinuierlichen Ablauf für eine Produktionssteigerung auch in diesem Bereich. Das Transportleitsystem orientiert sich bei der Bewältigung seiner Aufgaben an einer Reihe von betrieblichen Vorgaben und organisatorischen Festlegungen und stellt einen in jeder Situation optimalen Materialfluss durch das gesamte System sicher. Ein erfahrener Partner spart Lehrgeld Die flexible Automatisierung des Materialflusses im Strangpresswerk verlangt mehr als andere Logistiklösungen ein reichhaltiges Maß an Erfahrungen auf diesem Spezialgebiet. Die Problematik, der sich Presswerk und Logistikpartner stets aufs Neue gegenüber gestellt sehen, ist zunächst einmal darin begründet, dass es sich um individuell gewachsene Strukturen handelt. In praktisch jedem Werk liegen die Verhältnisse anders: Die lokalen Gegebenheiten, die existierenden Anlagenteile und ihre Aufstellung, das Produktionsprogramm, die unternehmerischen Zielstellungen und andere Punkte – die unterschiedlichen Randbedingungen machen eine Lösung von der Stange praktisch unmöglich. Herrmann und Hieber hat das als erstes Unternehmen erkannt und befasst sich seit nunmehr fast 20 Jahren mit dieser ganz speziellen Thematik. In dieser Zeit wurden in zahlreichen namhaften deutschen und europäischen Presswerken insgesamt ca. 50 Automatisierungslösungen installiert – von singulären Transport- und/oder Lagerlösungen bis hin zum komplett automatisierten Materialfluss im gesamten Werk. Auf diesen Erfahrungen aufbauend ist Herrmann+Hieber heute der Logistikpartner der Strangpressindustrie in Fragen des innerbetrieblichen Profiltransportes. Autoren Dipl.-Ing.

In total, each furnace accommodates two fivehigh rack stacks next to one another, so that HGW also has sufficient ageing capacities for future needs. The system’s main storage area has been located directly under the crane. To have sufficient storage capacity this area is designed so that in each case two rack stacks are arranged one behind the other. The system is also responsible for dealing with empty scrap crates and their removal. A superlative crane unit The automatic crane is an indispensable transport means for the automation of rack transport in the extrusion plant. With crane transport, rack movements are possible which could only be carried out with difficulty using floor-level conveyor technology. In most cases the free areas on the ground required for them are not sufficient. The automatic crane now installed at Gutmann can be regarded as the most dynamic of its type so far built by Hermann+Hieber. The crane can serve two extrusion presses, the section store, all the ageing furnaces, the packing area and in addition the scrap transport. That represents a new dimension never before realized anywhere. For structural reasons the span width of the three-axis crane could only amount to 13 metres. Yet, this special crane can serve two rack stacks, one behind the other and each 8 metres long. This is because the trolley carriage with its integrated gripper can push the racks under the crane gantry. The same principle is also used for serving the ageing furnaces. Thanks to this measure, at HGW not only is the necessary number of ageing furnaces made available, but also the planned storage capacity for packing. This arrangement of the automatic crane entailed finding solutions for a number of detail problems: • Since the racks extend beyond the crane gantry on both sides, special safety requirements had to be fulfilled by the design of the drive and control systems. In particular it had to be en- ALUMINIUM · 7-8/2008 TECHNOLOGY sured that the crane gantry supports arranged in the storage area do not collide with the racks being transported. For this a new safety concept had to be developed, based on faultless … mit Unterstützung des Logistikspezialisten Herrmann+Hieber … with the support of logistic specialist Herrmann+Hieber position determination and reliable signal transmission. Besides, the supports are positioned a relatively large distance apart (which also increases the available storage area). • Another important aspect was the high temperatures to which the crane is exposed when serving the ageing furnaces. When a furnace is open the crane, and also its gantry, are exposed almost to the temperature in the furnace. It therefore had to be verified for every detail of the structure whether that temperature loading could be withstood. Autonomous control of the automatic operation The investment in rack transport automation pays dividends in many respects. Transport damage, which is fairly commonplace during conventional transport by floor-level conveyances, can be avoided completely. Moreover, as a rule the extrusion lines are more productive as the result of trouble-free ALUMINIUM · 7-8/2008 automatic operation. In addition, operation is less costly in terms of personnel and transport means. To manage the complex tasks involved in an automated sequence, the plant is controlled by a transport management system which is in turn connected to the master process control system of the extrusion plant. The process control system only transmits the job data, including the working steps to be carried out, to the transport management system. The latter is solely responsible for proper implementation of all the necessary transport movements. The transport management system is responsible for the optimum utilization of the ageing furnaces. Only by specifying the furnace programme in full is it possible to carry out optimally all the procedures at the ageing furnaces, such as intermediate storage, batch-building before, in, and after the furnace, furnace programme selection, starting-up of the furnace, manipulation of the furnace cover and quality inspection after ageing. For quality assurance, the temperature variations determined for each charge are communicated to the quality management of the extrusion plant for documentation purposes. In the subsequent packing area too, the transport management system ensures greater productivity by virtue of intelligent storage strategies and a smooth and continuous procedure. For the management of its tasks the transport management system takes into consideration a series of operational specifications and organizational rules, and ensures optimum material flow throughout the system in any situation. An experienced partner saves the cost of trial and error More than other logistical solutions, the flexible automation of material flow in an extrusion plant demands a great deal of experience in this special field. The problems faced again and again by extrusion plants and their logistics partners stem, in the first place, from the fact that they have all developed individually. The situation is practically any plant is different: local circumstances, the existing plant components and their installation, the production programme, the company’s objectives and other points – the different boundary conditions, in other words – make it virtually impossible to apply any ‘off the shelf’ solution. Hermann+Hieber was the first company to recognize this and has now been dealing for almost 20 years with this very special subject area. Over that period a total of about 50 automation systems have been installed at numerous German and European extrusion plants – from individual transport and/or storage solutions to completely automated material flow systems throughout the plant. Building on that experience, today H+H is the logistics partner of the extrusion industry when any matter of section transport within the plant is concerned. Authors Dipl.-Ing.

Rieth, Meerbusch In the last issue of ALUMINIUM the Managing Director of Danieli Fröhling, Jörg Schröder, explained the importance of his company as the competence centre for aluminium rolling and strip processing lines within the Danieli Group. The following contribution looks at some of the technical highlights of the company’s product range, and reports about current orders. In the aluminium sector, the company now known as Danieli Fröhling has until now mainly made a name for itself with strip processing lines. In recent years, wherever a new aluminium, rolling plant for high-end flat products has been set up, the customer has always decided for a strip-cutting line from Danieli Fröhling. Yet, the company has great plans to achieve a similarly important position in the field of aluminium rolling plants as in the cutting sector. The basis for this is on the one hand years of experience in 4-high, 6-high and even 20-high rolling mills for both copper and brass strips and for stainless and high-alloy steel strips in all thickness ranges 62 down to 10 μm foil. In addition, the sister company Danieli Wean United is continuing the traditions of the two US American rolling plant constructors Wean and United Engineering in the building of hot- and cold-rolling plants for wide steel strips. In recent years this sector, as a member of the Danieli group, has achieved a notable extension of its market position in the booming steel strip market, in which interesting new developments such as 6-high cold-rolling mills for wide strip have also appeared. What could be more obvious than to combine the experiences of the Danieli group in rolling plant construction and use the result to enter the aluminium sector? But to live up to Danieli Fröhling’s claim not simply to come on the market with a few attractive ‘Me-too’ solutions, what Danieli Fröhling offers is a particularly attractive ‘specialty’ for the operator. To put it briefly: under the leadership of Danieli Fröhling as the competence centre for flat aluminium products within the group, the three exclusively collaborating partners Danieli Fröhling, Danieli Automation and Innoval Technology, with their ‘Diamond Mill’ concept, offer a unique combination of competence in rolling mill construction, in automation and process control, and in long years of operational know-how, which provides both experienced operators and, in particular, those who are new to the aluminium business an ‘all-round problem-free package’ with only one partner with responsibility for the project, who can however, rely on the abundant experience of his partners from the initial planning stage right up to the operation of the plant. The details of this strategy have already been highlighted in an interview with Jörg Schröder in ALUMINIUM, issue 06/2008. Accordingly, below we shall focus primarily on the design aspects of the rolling mills intended for the ‘Diamond Mill’ concept. Numerous application sectors for ‘Diamond Mills’ The standard ‘Diamond Mill’ rolling unit for hot- and cold-rolled aluminium strips is again the 4-high mill. As a rule, as a non-reversing stand this ALUMINIUM · 7-8/2008 TECHNOLOGY Single-stand 6-high rolling mill strips they enable better control of the strip flatness, rapid adaptation to frequently changing pass schedules and strip dimensions, especially when changing from wide to narrow strips. Another important feature is the improved compensation of thermal crown from the previous rolling pass. Moreover, 6-high stands enable rolling with steeper acceleration and deceleration ramps without adverse effect on strip flatness uniformity. A 6-high stand of this type (in this case for copper strips), which satisfies all the criteria of modern rolling plant engineering, is currently being built by Danieli Fröhling for strip widths up to 650 mm and rolling speeds up to 800 m/min for Chinalco Luoyang Copper Co. in China. This company of © Creuna. Foto: Gettyimages (Hydro 2008) does all that is needed in the sector of strip and plate hot-rolling and for many cold-rolling processes. This traditional structure, with two working rolls and two back-up rolls, is mainly used where the deformation planned demands a solid mechanical stand design which, however, depending on the task, is supported by the most modern actuators for automation known in the field of rolling mill engineering today. In addition, in special cases coldrolling mills are also offered in the form of a non-reversing 6-high stand with two relatively slim working rolls, two intermediate rolls and in each case two back-up rolls. 6-high stands have been developed by Danieli specially for satisfying strict demands on strip profile, especially in the area of the strip edges, strip flatness, and high reduction rates, for example in high-productivity stainless steel rolling plants and also for the most recent copper rolling mills, and are widely used.

Going beyond the standard of modern 4-high mills, Danieli Fröhling’s foil rolling mills are specially designed for high-speed rolling conditions at up to 2500 m/min, a minimum foil thickness of 5.5 μm and foil widths over 2000 mm. They contain specially designed bearings created particularly for these high speeds and the present-day requirements of rolling plant operators. At rolling speeds of up to 1800 m/min the back-up roll bearings consist of four-row cylindrical roller bearings and two-row axial bearings. To keep the bearing temperature as constant as possible, the chocks of the backup rolls have drilled coolant passages near the outer ring of the bearings. At speeds higher than 1800 m/min Danieli Fröhling uses the so-termed ‘DanOil’ bearings already developed by Danieli in 1998. These are hydrostatic oil flood bearings suitable not only for the highest rolling speeds but also for very high rolling forces, which have meanwhile come to be highly regarded in technical circles. The entry guides are equipped with a specially arranged spray coolant distribution system, which ensures uniform temperature distribution in that area. Furthermore, the spray nozzle arrangement is optimized so that the quantity of coolant is minimized, which makes production very economical. The hot-, cold- and foil-rolling mills are supplemented by the handling equipment required for each application, such as roller tables, coilers and shears. So much for the mechanical standard of the new rolling plant concept. But a ‘Diamond Mill’ has much more: aluminium strips of whatever rolled condition and thickness range are exposed to keen competition from competing materials, which can only be overcome by the greatest rolling plant productivity and optimum strip geometry and strip surface quality. The successful use of a mechanically sound rolling mill is therefore only possible if it is equipped with technologically highly effective actuators which, for their part, are controlled by well-developed process models. This is precisely the point of attack for the ‘Diamond’ concept. To implement it, Danieli Fröhling’s partners Danieli Automation and Innoval Technology work hand in hand. Danieli was one of the first plant engineers to recognize the importance of rolling plant automation and has installed and perfected it in countless plants for both steel and nonferrous products. For its part, on the one hand Innoval Technology has many years of experience in the production and processing of the most varied aluminium alloys. On the other hand, available to the company are all that it needs to investigate material specimens in order to establish the influence of the pre-material but also the effects of process variations. Thus, together Danieli Automation and Innoval Technology can provide an aluminium rolling plant with the optimum process needed for the task in hand. Examples of the successful use of such process models determine the technology of ‘Diamond Mill’. For example, the control of strip profile during hot rolling or flatness during cold rolling depends on the ability to influence the roll gap accurately over the entire speed range. This also applies during the acceleration phase, in which the rolling forces change markedly with the condition of the roll gap. Good set-up models are also important for establishing exactly the starting positions of the actuators and thus the minimizing of out-of-tolerance sections at the beginning and end of the strip. Very important for Foil rolling mill 64 ALUMINIUM · 7-8/2008 TECHNOLOGY the rolling process is also controlled temperature management by spray cooling of the working rolls, in the design of which Innoval’s long experience in the optimization of aluminium rolling plants plays an important part. Here, minimizing the use of lubricant also contributes importantly towards environmental protection. Minimization of the setting-up and idle times is another important feature of ‘Diamond Mill’. For this, they are equipped with rapid-adjustment possibilities, automatic roll change, and provisions for the simple performance of inspection and maintenance work. For Danieli Fröhling the overall Diamond Mill concept naturally also includes the use of the most modern peripheral and auxiliary equipment. Sophisticated cutting technology for aluminium strips Edge-trimming, slitting and cut-tolength lines made by Danieli Fröhling have special features thanks to long years of experience and continual further development, with which the company addresses the strictest individual requirements on the market and therefore, in deviating from standard lines for ordinary needs, can lay claim to the attribute of ‘excellence’. This is also reflected in the corresponding ‘premium’ prices for Fröhling equipment, although it should be borne in mind here that the true cost of a plant is determined not just by its purchase price, but rather, as the sum, of all costs over the entire life of the plant. Besides the price of the plant other factors are important in this, such as maintenance expenses, the need for spare parts, running costs, etc. These are the points on which the company focuses in its plant concepts and is thus always rewarded with orders from existing or new customers. Good examples of the success of this attitude are provided by a look at the current orders received by Danieli Fröhling from important aluminium industry customers. High-speed trimming technology Owing to their continual further development, trimming lines from Fröh- ALUMINIUM · 7-8/2008 Exit side of a slitting line ling have made their mark on the state of the art in highly productive companies of the NF metals industry for many years. Particularly appreciated are the design criteria established by the Fröhling designers for speed, productivity and material tolerances. The company points out that it is now the only plant manufacturer in the world which supplies trimming lines that run at constant speeds of up to 1600 m/min in day to day production operation. Based on a trimming unit for 1500 m/min delivered to Aluminium Norf in Germany at the end of the 1990s, China’s fastest trimming unit for aluminium strips so far went to Longkou Guansheng Hydrophile Aluminium Foil Co. Ltd., a company belonging to the Nanshan group. There, again at 1500 m/min, the machine trims both can body stock and foil stock strips in the width range from 950 to 2100 mm and of thickness 0.25 to 0.7 mm, brought in as 30-tonne coils. This customer’s satisfaction has already led to follow-up orders from other Chinese plants, including Chinalco Southwest Cold Rolling Co. Ltd. (CSWA) and Chinalco Ruimin. A further trimming speed increase is provided for in the CSWA plant, which is designed for a plant speed of 1600 m/min with a speed of 0 to 30 m/ min for threading the strip in and out and a capacity of 220,000 tonnes per year. This is used both for the intermediate trimming of strips which are subsequently to be rolled again, and also for finished material before shipping. The strips, made from the alloy groups 1xxx, 3xxx, 5xxx and 8xxx, are 0.1 to 0.65 mm thick, 800 to 1800 mm wide, and are supplied in the plain rolled, waxed, or coated condition in coils weighing 22.5 tonnes. Besides the mechanical equipment, Danieli Fröhling is also responsible for the electric and automation aspects. In addition to the actual drive technology, Danieli also supplies the level-1 and level-2 systems. The control and regulation functions of level2 are used, among other things, for on-line monitoring and for machine and process supervision, to ensure the best possible production performance and product quality of the plant. The plant has already been delivered and assembly is to begin shortly. Slitting lines Similarly advanced is Danieli Fröhling’s position in relation to slitting lines. A good example is the slitter, including the packaging line, which recently began operating at Alcoa Europe Köfem in Hungary. The design of the unit is based on the most up-todate knowledge about the slitting of thinner and softer materials by circular blades. Cold-rolled hard and soft aluminium strips 0.05 to 0.4 mm thick and with a maximum run-in width of 1700 mm can be slit into up to 120 strips and coiled. © 65 TECHNOLOGY to the vacuum braking roll, whose The particular aim was to avoid suruse is limited to strips of maximum face damage and achieve the largest thickness 1.2 mm, the ECBS covers possible finished coil diameter.

In this connection, Danieli Fröhling may well be the only metallurgical plant constructor to associate the interesting field of lithography strip with two different production steps: both in the finishing of aluminium rolling plants as in the case of Hydro Aluminium, and in further processing, as with Kodak, AgfaGevaert and Fuji Photo. The most important component of Danieli Fröhling’s cut-to-length lines is the drum shear, which is also used in the trimming lines for cutting up the out-of-tolerance beginning and end sections of the strips. The drum shear can be used for immediate length changes of successive sections, and in this, reliably achieves a tolerance of ± 0.125 mm. Worthy of special mention is the enormously long life of the shear blade, which only has to be re-ground after about ten million cuts. Like the rolling mills, so too the various shear lines are supplemented by highly effective automation systems with process models matched to the plant characteristics in each case. In addition, Danieli Fröhling offers its customers in the NF sector the metallurgical Supply Chain Management (‘METscm’) system specially developed by Danieli Automation. This incorporates the rolling plant or shearing line into the overall order- tracking and so ensures the greatest possible plant productivity. Author Dipl.-Ing.

Galeria, Stand G35 www.danieli-froehling.de OFFICIAL MEDIA PARTNER ALUMINIUM · 7-8/2008 TECHNOLOGY Alloy manufacturer and extruder join forces Aluminium has many attractive material properties and these have led to it being increasingly used in an ever-broader range of applications. The metal’s appearance is aesthetically appealing to all age groups: reassuringly reliable yet young at heart. Good looks coupled with ease of processing have opened up markets for the metal as diverse as the automotive industry and building and construction; interior decoration is also a field where designers take full advantage of aluminium’s aesthetic qualities. To be able to demand a premium price, products need to be completely free from blemishes and imperfections that might detract from an otherwise excellent visual appearance. So-called ‘bright-finish alloys’, which can be polished electrolytically or chemically to give a high-gloss surface finish, have been used for many years in applications that need a bright and shiny appearance, or where reflection of heat or light is important. The materials are typically purer grades of aluminium, such as Al99,98R. Two companies based in Germany, Trimet Aluminium AG from Essen and Gerhardi Alutechnik GmbH & Co. KG from Lüdenscheid, have now adopted a novel approach by combining a highpurity alloy with a forming process that produces extrusions that have a particularly high-grade surface finish. The products are suitable for high-volume applications, such as for the automotive industry. As the companies point out, such an approach demands close co-operation between the producer of the extrusion billets and the extruder in order to detect and analyze defects, and take the necessary steps to improve the production chain. trimal BQ process Trimet has introduced its trimal BQ (brilliant quality) process at its primary aluminium smelter in Essen to pro- ALUMINIUM · 7-8/2008 Photos: Trimet Combined approach to bright finish products Unacceptable oxide lines and TiB2 agglomerates in a grain refinement rod duce these alloys. The process covers all aspects of the production process starting with the choice of the alumina used in the smelter, via the pots used for the actual electrolysis through to customized homogenizing of the end product. A wide range of steps is taken to avoid any undesirable impurities such as inclusions forming or entering the metal. The starting point is the alumina used as the raw material for the electrolysis process: • The quality of the alumina is carefully monitored and only raw material that is sufficiently low in iron, silicon, calcium and sodium is used. • Although it is common practice in primary aluminium smelters to use alumina for dry scrubbing of the waste gases, thereby extracting fluorides which are subsequently recycled with the alumina, this alumina is not used to produce bright-finish alloys to avoid a possible source of contamination. Important measures are also introduced during the electrolysis process that converts the alumina to aluminium: • Electrolysis is only carried out in special pots reserved specifically for producing high-purity aluminium. This avoids any possible pick-up of contaminants. • In the interests of quality, the aluminium in the high-purity pots is analyzed more frequently than is normally the case, namely every 48 hours. • A special control system keeps the level of the electrolyte in the bath at a constant height. • Attention is also given to the anodes used in the electrolysis cells. Not only do the anodes used have a low iron content, they are also replaced more frequently than is usually the case. Although this measure incurs added costs, it avoids contamination due to iron from the pins that fasten the anodes to the rods. • The anodes used are coated with a special mixture consisting of crushed bath and production purity alumina; this protects the anodes against oxidation. Melting The level of care that is taken to avoid the ingress of undesirable impurities and inclusions in the potroom is maintained in the casthouse: • In the melting furnace, cold metal can be used for melting or if molten metal from the potroom is used, cold metal is added to cool the molten metal down to the desired holding temperature. In either case, only ingots or sows from in-house production are used. Tests have shown that from an inclusion point of view there is no difference between using molten aluminium from the potroom or cold metal as the starting material. • Alloying elements are added in the form of master alloys: a) Only master alloys or other additions to the melt from certified suppliers are used and these are chemically analyzed and checked for non-metallic inclusions and microstructure. b) The master alloys have to conform to DIN-EN 575. c) The order in which the alloying elements are added to the melt is important. d) A sample of every heat of the © 67 TECHNOLOGY grain refinement rod used is analyzed for possible impurities, such as oxides, and to determine the morphology of the nucleants (TiB2, Al3Ti) e) Master alloys are not added in the casting furnace. Holding As is common casthouse practice, care is taken to ensure that dross on the surface of the molten metal is skimmed off and not allowed to enter the metal. The casing process in Essen has been specially developed for trimal BQ. After stirring, skimming, holding and sampling, the melt is transferred to the casting furnace via a launder system. Here it is essential that turbulence is avoided and that the transfer is carried out under laminar flow to avoid dross formation and hydrogen pick-up. In the casting furnace, melt cleaning is performed using the impeller technique and an argon/chlorine gas mixture. This removes non-metallic inclusions and hydrogen from the melt. In the holding furnace, the cleanliness of the melt is checked from time using a Porous Disc Filtration Apparatus (PodFa). The measurement involves passing the molten metal through a fine filter and analyzing the deposit left behind. The technique involves preparing metallographic samples and examination of the inclusion content left behind on the surface of the fine-filter disc. The interpretation of the metallographic sections requires an experienced technician. The results are expressed in terms of Tool for extruding bright finish alloys 68 area fraction of inclusions observed as a function of metal volume passing through the test filter; the standard unit is mm2 of inclusions/kg of melt. The filter system used for the melt is very effective and removes most of the inclusions. It also functions effectively over the entire casting cycle. If end-product rejection rates are to be kept to a minimum, the inclusion content must not be allowed to exceed 0.005 mm2/kg. Casting Billets 140 to 548 mm in diameter are produced using spout and float casting technology. The casting process is automatic. Tilting of the casting furnace is controlled via the level of the melt in the launder using a laser technique. It is important that the melt in the casting furnace and the launder are at the same level to avoid the so-called ‘waterfall effect’; splashing would lead to undesirable oxidation of the molten metal and the formation of inclusions. The metal is cast into continuous-casting moulds specially chosen for the trimal BQ. After removing the solidified billets, the surface of each billet is checked visually for any signs of surface defects. Ultrasonic testing is used to check for possible internal cracks in the base area of the billet. The billets are subsequently homogenized, the specific details of which depend on the customer and the final product. The duration and temperature of the homogenizing treatment and in particular the cooling rate after homogenizing have a significant effect on the properties of the final product. The homogenized billets are subjected to metallographic examination using light microscopy. A potential serious problem is pre-solidification, which can adversely affect the appearance of the finished part. Other checks include measurement of the depth of the shell zone, which is defined by the customer, the grain structure, which should be uniform, and the grain size. Feather crystals, nonmetallic inclusions and gas porosity are undesirable and must not exceed prescribed limits. Geral BQ Gerhardi Alutechnik uses billets supplied by Trimet to produce its Geral BQ extruded shapes, which are used in a wide range of applications: • Tooling technology: the desired level of surface finish cannot be attained using the tooling normally used for aluminium extrusion. The highly wear-resistant extrusion tooling used by Gerhardi is based on a special tool steel and a defined coating system. • Extrusion parameters: the billet is preheated to a temperature of 400 to 500°C and the extruded shape is subjected to controlled cooling, the details of which depend on the intended application. • The extruded part is then subjected to a final heat treatment. When producing high quality extrusions for decorative applications, strict monitoring of the production parameters is essential. If the Geral BQ extruded shape is used to make trim for a car, a stretcher and roller process is used to bend it to the desired shape. The material has excellent bending properties, allowing small bending radii to be achieved, and there is only minor orange peel thanks to the high degree of homogeneity. After forming, the finished shape is first sanded and polished. The homogeneous structure of the alloy coupled with the good surface finish of the extruded part results in less sanding and polishing being needed at this stage and thus considerable cost benefits. ALUMINIUM · 7-8/2008 TECHNOLOGY is about 15,000 tonnes a year, and it is still growing. Geral BQ is used in the automotive, furniture and lighting industries. In the automotive industry, which is a major driving force for the use of decorative aluminium parts, Geral BQ is used both inside and outside the vehicle: for example, for trim, roof racks, decorative fittings and door handles.

According to Trimet and Gerhardi Alutechnik, the market in Europe for extrusion billets used to produce surface-sensitive aluminium products www.trimet.de OFFICIAL MEDIA PARTNER The Hertwich Engineering ‘3E’ concept Efficient, economical and ecological melting of swarf and scrap Plant configuration – swarf remelt plant There are serious disadvantages associated with the methods for remelting swarf which have been in common use for a number of years and these tend to have a negative impact on cost effectiveness: • low metal yield • high energy costs • extensive handling • emission problems with waste gases and the solid residue (salt cake). For instance, the rotary furnace concept achieves a somewhat low metal yield as well as producing environmentally problematic salt cake. By using induction type furnaces, waste gases need additional treatment to meet environmental requirements. Induction type furnaces require very clean charged material and often need mechanical intervention to overcome bridging. They are also associated with high specific investment costs, frequent expensive relining and high operating costs for electricity. Mechanical mixing of swarf is associated with the need for frequent maintenance due to damaged or worn impellers or other stirring devices. With conventional methods, swarf still needs to be dried in a separate step and allowed to cool down, thereby again absorbing moisture. The common practice of half-heartedly drying the swarf to some 200°C only reduces the moisture content without actually resolving the issue. In a competitive environment, these are serious aspects that call for genuine improvements. A well-proven concept developed and patented by Hertwich Engineering eliminates ALUMINIUM · 7-8/2008 Hertwich Due to increasing use of aluminium castings and forgings, for example in the automotive industry, swarf generation is on the rise. Swarf generation is now estimated to exceed several million tonnes a year worldwide. It is therefore important to have a very economical and environmentally sound method of returning such huge quantities of waste material to the material cycle. these disadvantages and sets the industry benchmark for the three Es: • Efficiency: best metal recovery, thorough process integration • Economy: cost effective, lean operation • Ecology/environment: surpasses even the most stringent emission limits. The 3E concept is characterized by the following features: • After the usual swarf treatment steps like centrifuging, breaking and iron separation, swarf is first fed into a high speed swarf dryer and then immediately charged into the furnace and melted in a continuous operation. • The swarf dryer and melting furnace are combined in a single thermomechanical system. Hot gases © 69 TECHNOLOGY Continuous melt rate, depending on plant size Specific energy consumption (natural gas) for drying, gasification and melting Dross generation relative to dry charge weight Aluminium content of dross Effective metal loss Cost of transporting and handling swarf Table: Process data from the furnace chamber are used to heat the swarf in the dryer. These hot gases are mixed with the circulating gas flow in the dryer. Exhaust gases from the dryer, which also contain hydrocarbons, are ducted back into the melting furnace, where the hydrocarbons burn in the hot atmosphere at approx. 1000°C with a slight excess of oxygen. An expensive, energy-intensive after-burner system is therefore not required, but the burning of the hydrocarbons from the swarfdrying process contributes substantially to the energy requirement of the melting furnace. • The swarf is rapidly heated to some 400°C within a fraction of a second and the hydrocarbons and moisture evaporate completely. This prevents further oxidation of the swarf due to lengthy exposure to high temperatures. • The dryer and melting furnace are combined into a single process so the swarf is hot when it is fed into the melt and its thermal energy is thus utilized. • The swarf is free from moisture and hydrocarbons. If swarf is allowed to cool down to ambient temperature inside a building, it reabsorbs 0.1 % of its weight in moisture within a short period of time (which is equivalent to 1 kg per tonne) – due to the van der Waals force. If this moisture enters the melt, it will cause an increase in hydrogen content as well as oxidation losses. • During charging into the furnace sidewell, hot swarf comes into contact with a vertical, downward flow of molten metal generated by an electromagnetic linear-motor, and is quickly submerged into the melt. The swarf melts by direct contact with the molten metal without any oxidation. There are no moving parts in contact with the melt contact. • A linear motor attached in a similar way can be used as a launder pump 70 2.0 – 5.0 t/h 600 kWh/t, (930 BTU/lb) < 1.5 – 2.5% * 60 – 80% 0.8 – 1.5 % substantially reduced * depending on age of swarf and oxides present for safe and easy tapping of the melt, by either transferring the metal into a holding furnace or into crucibles. Advantages of Hertwich Engineering’s 3E concept: • Lowest melt losses, hence highest metal recovery • Lower energy consumption • Minimum manpower requirement for operation and maintenance • Better metal quality (less hydrogen) • Meets stringent environmental standards • Occupation safety, EHS compliance. In large foundries and forging plants with an annual swarf generation of 5,000 to 20,000 tonnes a year or more, it is practical to recycle the swarf on site. This saves the costs of handling and transport. The first swarf remelt plant of this type was commissioned for a prominent German producer of forgings, where swarf is delivered to the swarf dryer directly from the machining centres. This application typically requires a co-flow dryer, where swarf is heated within a few seconds, eliminating further oxidation on the swarf surface. Other plants have been installed for wheel manufacturers, who also recycle their scrap wheels. These wheels are charged through a wheel lock, where they are preheated and delacquered, and then fed into the melt automatically. One plant of this type is in operation at a German primary aluminium producer. The plant operates on purchased swarf, and is therefore equipped with additional silos and associated swarf preparation. Hertwich Engineering offers specific types of swarf dryer to process different forms of swarf. For instance heavy or stringy swarf is most efficiently processed in drum-type dryers. Retention time is less than three minutes. The system is being adopted, with a slightly modified design, for thin gauge and shredded aluminium scrap. Maximum metal yield and minimum costs are achieved in this application, too. Summary Hertwich Engineering’s 3E concept for the economical and ecological melting of swarf and scrap has proven to be thoroughly efficient after years of operation. Clients have confirmed that the system best meets their requirements and is clearly superior to conventional methods. N Hertwich Engineering is an exhibitor at ALUMINIUM 2008 in Essen.

N Treatment of aluminium salt slag Agor wins Agor mit BDI-Umweltpreis ausgezeichnet environment award Der Bundesverband der Deutschen Industrie (BDI) hat jüngst die Agor AG, Köln, sowie ihre Tochtergesellschaften Alsa GmbH, Hannover, und Alsa Süd GmbH, Töging, als eines von fünf Unternehmen mit dem „BDI Umweltpreis für die Industrie 2007/2008“ ausgezeichnet. Die Agor/AlsaGruppe gewinnt den Preis in der Kategorie „Kreislaufwirtschaft, Recycling und Abfallmanagement“ für ihr Verfahren zur Aufbereitung von Aluminiumsalzschlacken. Der BDI würdigte die Träger des Umweltpreises als herausragende Beispiele dafür, dass nachhaltiges Wirtschaften Anspruch und Realität in der deutschen Industrie sind. Fotos: Agor Mit dem in den 1980er Jahren entwickelten Alsa-Verfahren hat Agor das Recycling von Salzschlacke auf ein hohes technisches Niveau gebracht. Salzschlacke auf dem Weg zur Aufbereitung Salt slag on its way to being recycled 74 Das Vollrecyclingverfahren ist eine ressourcenschonende, umweltkonforme und auch wirtschaftliche Alternative zur Deponierung von Salzschlacken. Insbesondere die 2007 im bayerischen Töging in Betrieb genommene dritte deutsche Salzschlackenanlage stellt einen neuen Meilenstein in der Aufbereitungstechnik dar, was die Jury des BDI-Umweltpreises mit der Auszeichnung honoriert. Salzschlacke entsteht beim Einschmelzen von Sekundäraluminium: vorwiegend in gasbefeuerten Drehtrommelöfen. Dabei werden Aluminiumschrotte und -krätzen unter Zugabe von Schmelzsalz eingeschmolzen – einem Gemisch aus Natriumchlorid, Kaliumchlorid und Flussspat. Die daraus entstehende Salzschlacke enthält die werthaltigen Bestandteile Aluminiummetall, Schmelzsalz sowie diverse Metalloxide, vorwiegend Aluminiumoxid. Beim Alsa-Prozess wird in einem ersten Schritt durch trockenmechanische Trennverfahren das metallische Aluminium zurückgewonnen. In der anschließenden Nasschemie wird in einem mehrstufigen Löseund Rekristallisationsverfahren das Salz herausgelöst und die unlöslichen Metalloxide zu einem Sekundärrohstoff für die Mineralwolle- und The Agor/Alsa Group recently won an environment award from the Federation of German Industries (BDI) for its aluminium salt slag treatment process. With its Alsa process developed during the 1980s, Agor has put the recycling of salt slag onto a higher technical plane. The process for the complete recycling of salt slag is a resource-conserving, eco-compatible and economic alternative to dumping. The salt-slag processing plant that began operating in 2007 in Bavaria, the third in Germany, represents a new milestone in the slag-processing technology. Salt slag is formed when secondary aluminium is melted down, an operation that is mainly carried out in gas-fired rotary drum furnaces. Aluminium scrap and dross is melted down together with additions of a flux – a mixture of sodium chloride, potassium chloride and fluorspar. The resultant salt slag contains valuable constituents: aluminium, flux and various metal oxides, mainly aluminium oxide. During the Alsa process, metallic aluminium is recovered in the first stage using a dry-mechanical separation process. Multi-stage wet chemical processes are then used to dissolve out and recrystallize the flux; insoluble metal oxides are processed into a secondary raw material for use in mineral wool and the cement industry. The wet chemical process is a closed loop as far as the water is concerned and is thus completely free from effluent. The gases phosphine and hydrogen sulphide form ALUMINIUM · 7-8/2008 MARKETS AND TECHNOLOGY during the treatment process and are adsorbed in active charcoal filters. The dust from waste-gas cleaning is fed back into the process and the ammonia removed during washing operations is converted to ammonium sulphate, a nitrogen fertilizer for the fertilizer industry. The only waste produced is from the active charcoal used in waste-gas cleaning. With secondary aluminium production of approximately nine million tonnes a year worldwide, some 4.5 million tonnes of salt slag accrue annually. The Agor/Alsa Group processes some 430,000 tonnes a year and regards itself as the world’s largest complete recycler of aluminium salt slag. The know-how of the Alsa process lies is in the efficient interplay between the separate steps of the complex wet-chemical process, the selection of materials for the plant components and the expertise in operating such complex processing plants. In the ‘Reference Document on Best Available Techniques (BREF) in the Non Ferrous Metals Industries’, which is currently being revised in accordance with Article 16 (2) of the IPPC Guideline*, the process, which is already recognized as the Best Available Technology (BAT), is again the preferred technology. * Council Directive 96/61/EC of 24 Sept. 1996 concerning integrated pollution prevention and control N Zementindustrie konfektioniert.

These air channels, which are also called ‘whistlers’, play an important role in maintaining quality. However, it is very time consuming to pierce the vent holes manually or mechanically. ABB offers an efficient alternative that also produces very good quality holes and can even be used to produce holes that are inclined to the vertical. The ALUMINIUM · 7-8/2008 company says the new FlexMouldVenter robot function package can easily be retrofitted. The positioning and quality of vent holes pierced manually depend strongly on the operative and operational factors. Devices that allow piercing to be performed mechanically require down time, which reduces productivity; however, in practice there is often a need for product © Robotergestütztes Luftpfeifenstechen in Sandgussformen Entlüftungslöcher in Sandgussformen sind zum Entgasen während des Gießprozesses unabdingbar. Diese auch Luftpfeifen genannten Luftkanäle haben eine wichtige qualitätssichernde Funktion. Doch ist das manuelle wie maschinelle Luftpfeifenstechen zeitlich aufwändig. ABB bietet eine rationelle Alternative, die zusätzlich sehr gute Lochqualität erzeugt und sogar schräg an© 75 MARKT UND TECHNIK gesetzte Stiche realisiert. Das neue Roboter-Funktionspaket „FlexMouldVenter“ lässt sich einfach nachrüsten. ABB Automation Position und Qualität manuell gestochener Luftpfeifen hängen stark von individuellen und umweltbedingten Einflussgrößen ab. Vorrichtungen zum maschinellen Stechen benötigen produktivitätsmindernde Rüstzeiten; die aktuelle Nachfrage verlangt aber häufig Produktwechsel und schwankende Produktzahlen bis zur Losgröße 1. Dies erfordert beim Gießen inklusive Vor- und Nacharbeit eine hohe Flexibilität, die durch das Funktionspaket von ABB Robotics optimal erfüllt wird. Ein Roboter sticht zum Beispiel im Sekundentakt qualitativ hochwertige Luftpfeifen, bei Bedarf – im Gegensatz zur Mehrlochvorrichtung – auch in schräger Lage. Die Lochdurchmesser sind zwischen 5 und 10 mm wählbar, die Lochtiefe bis 650 mm, die Stechgeschwindigkeit Der Luftpfeifenstecher von ABB FlexMouldVenter from ABB 76 beträgt dabei bis 2,5 m/s. Eine automatische Nadelüberwachung sorgt für stets gleich bleibende Qualität. Sie erkennt auch Nadelverbiegungen oder -brüche. Die Positionier- und Wiederholgenauigkeit standardmäßiger Roboter ist heute so genau, dass sie die Forderungen beim Sandguss leicht und sicher erfüllen. Das Funktionspaket FlexMouldVenter Das ABB-Funktionspaket besteht aus einem universellen Roboter IRB 6620 inklusive dem Zubehör. Der elektrische Linearantrieb mit Führung zum Bewegen der Nadel ist voll in die Robotersteuerung integriert. Kabelmanagement, Nadelkontrollstation und eine spezifische Datenschnittstelle zur Anlagensteuerung komplettieren das Paket. Der Roboter lässt sich über der Formlinie oder neben ihr montieren. Nach der Installation erkennt er seine Startposition. Die Positionen für die jeweilige Form gibt ein Mitarbeiter über die Anlagensteuerung ein. Das Robotersystem bearbeitet alle gängigen Formkastengrößen. Geführt über die Bildschirmmaske gibt der Bediener die Koordinaten der jeweiligen Lochpositionen ein. Die Software wählt die Lochreihenfolge und optimiert so den Prozess. Weil die Nadel von der Modellseite her sticht, können Anformungen entfallen. Dies vereinfacht den Modellbau. Als Option verfügbar sind Systeme zum Messen der Stechkräfte, Hard- und Software für Sicherheitsmodule, Prozessüberwachung und -dokumentation, dezentrale Lochdatenverwaltung, Montageelemente und Dienstleistungspakete. N changes and fluctuating lot sizes, even down to single items. This necessitates a high degree of flexibility in the foundry, including preparatory work and finishing, and the function package from ABB Robotics offers an interesting solution. For example, a robot can pierce high-quality vent holes every second or so and if necessary – in contrast to multi-hole devices – also at an angle. Hole diameters between 5 and 10 mm are selectable, hole depths up to 650 mm are possible, which is equivalent to a piercing speed of up to 2.5 m/s. Automatic monitoring of the piercing tool ensures a consistently high quality. It also detects bending or breakage of the tool. The tolerances for positioning and repeatability of standard robots today are so accurate that they easily and reliably satisfy the demands of sand casting. The function package FlexMouldVenter The ABB function package consists of an IRB 6620 universal robot together with accessories. The linear electric drive with guide to move the piercing tool is fully integrated into the robot control. Cable management, piercing tool control station and a dedicated data interface with the control unit complete the package. The robot can be installed above or to the side of the parting line. After installation, it recognizes its starting position. An operator inputs the hole positions for the respective mould via the control unit. The robot system processes all common sizes of moulding box. The operator inputs the coordinates of the respective hole with the help of the screen mask. The software chooses the sequence in which the holes are made and thus optimizes the process. The piercing tool produces the hole from the pattern side so there is no risk of indents. This simplifies patternmaking. Optional extras include systems for measuring the piercing forces, hardware and software for safety modules, process monitoring and documentation, decentralized administration of hole data, mounting elements and service packages. N ALUMINIUM · 7-8/2008 CO M PA N Y N E W S W O R L D W I D E Rio Tinto Alcan Aluminium smelting industry Rio Tinto Alcan eyes accelerated AP50 expansion In its effort to be at the cutting-edge of aluminium smelting technology, Rio Tinto Alcan, Montreal, will accelerate a pre-feasibility study for two additional phases at its AP50 pilot plant in Saguenay, Quebec. The company could spend US$2bn to US$2.5bn to take the plant to 200,000 tpy. Preliminary work has already started on the first phase of the AP50 demonstration plant, which will begin with 44 aluminium smelting pots with initial annual production of 60,000 tpy starting in 2012. Power will come from company-owned hydroelectric plants. The pre-feasibility study will investigate whether to add another 140,000 tpy capacity to the pilot plant. The plan is to start with a 60,000 tpy plant, followed quickly by another 140,000 tpy and then a possible subsequent expansion to a total of 400,000 or 450,000 tpy. Rio Tinto Alcan is aggressively developing the smelting technology in order to maximize its longterm value as the partner of choice for aluminium smelting projects. The new technology is expected to reduce production costs. Bosnia smelter sell-off in doubt The privatisation of Bosnia’s sole aluminium smelter Aluminij Mostar could fail on the government’s refusal to subsidise electricity prices for the nation’s biggest exporter. “The government and Aluminij Mostar must find ALUMINIUM · 7-8/2008 common interest in terms of electricity prices, otherwise the privatisation of the company has no prospect”, Mijo Brajkovic told a news conference. Expensive electricity has stalled the sale of Aluminij Mostar to a consortium led by Swiss-based commodities trader Glencore. Glencore has offered to pay €76.8m for an 88% stake in Aluminij, which accounts for 50% of Bosnia’s exports. The remaining 12% stake is owned by Croatia’s sole aluminium maker TLM. Glencore linked the power cost with the price of aluminium on the London Metal Exchange MCU3 and said future investments would depend on how cheap electricity was. The management and the government – with a 44% stake each – negotiate each year how to solve electricity shortages. Trying to overcome the shortages, Aluminij is looking into a possibility of building a new thermoelectric power plant. Maaden-Rio Tinto joint venture to exploit bauxite reserves Early in June, Rio Tinto Alcan’s CEO Tom Albanese paid a one-day visit to MaadenMaaden (MM) mining group in Riyadh recently. This follows the signing of a multibillion joint venture agreement late in 2007 to exploit the considerable bauxite deposits in the north of the Kingdom and to produce downstream alumina and smelted aluminium. Following Rio Tinto’s successful acquisition of Alcan in 2007 Rio Tinto Alcan is the largest producer of bauxite and of refined alumina. The joint venture with MM mining group – 51% MM and 49% Rio Tinto – involves extracting bauxite, refining it to alumina and smelting it to aluminium. The first stage of the project would produce about 740,000 tpy of aluminium. The Saudi government hopes to see some of that metal going downstream to fabrication, but this was not Rio Tinto’s main business area. A power plant of 2,000 MW that uses heavy oil, will be a key step in the long lead-time items that would proceed over the next few months. The first metal is expected in late 2011 or early 2012. The total cost of the project, including power plant and mining, refining and first stage of smelting producing 40,000tpy, would be about SR37.5bn (US$10bn). The energy advantage is in cheap heavy oil, but this also requires capital investment in pollution control, scrubbing and environmental protections. The availability of oil, cheap energy and short transport distances was all part of the deal to make a competitive package against rising construction costs all over the world. India’s Nalco plans US$9.3bn expansion over five years India’s aluminium maker National Aluminium Co. Ltd. (Nalco) plans to invest 400bn rupees (US$9.3bn) over the next five years on overseas projects and domestic expansion. The investments include smelter and power projects in Indonesia, South Africa and Iran. Nalco is investigating three projects outside India, but plans to take up one or two of these on the basis of viability. Nalco has signed an accord with the Indonesian government for a 500,000 tpy smelter and a 1,250 MW captive power plant with planned investment of about 140bn rupees. The company was also exploring the possibility of setting up a smelter and power plant in South Africa where it could invest 160bn rupees. In Iran, the company plans to build a smelter in a joint venture. The smelter will have a capacity of 310,000 tpy and will be built in two phases. © 77 CO M PA N Y N E W S W O R L D W I D E The project would cost the company 80bn rupees. In India, the company will spend 70bn rupees in a mines and refinery complex in southern state of Andhra Pradesh and 85bn rupees on a smelter and power complex in eastern Orissa state. Nalco will expand its bauxite mining, smelting and refining capacities at its existing facilities with an expenditure of 60bn rupees. The other planned projects include an aluminium innovation park at Angul in Orissa, an aluminium rail wagon production venture with another state-run firm Bharat Earth Movers, and a cement plant. to acquire all of Montreal-based Alcan’s outstanding common stock for US$101 per share. Rio Tinto also was aware that Alcan’s board had agreed to recommend acceptance of Rio Tinto’s offer to shareholders. At about 2:30 p.m., the story broke on a major media outlet and was quickly picked up by other news organizations. Under Australian securities regulations, Rio Tinto was required to notify the ASX immediately upon the deal ceasing to be confidential. Rio Tinto did not request a halt until 3:40 p.m. The ASIC said that nearly US$65m worth of Rio Tinto shares traded between 2:30 p.m. and 3.40 p.m. Start-up of Sohar smelter UC Rusal and Ust-Luga company plan to create a trans-shipment complex Oman’s Sohar Aluminium, 20% owned by a unit of Rio Tinto, started production at its 350,000 tpy smelter. The smelter will take six months to reach full capacity, the company said in a statement, without giving current output. The US$2.4bn (Dh8.8bn) Sohar Aluminium joint venture is 20% owned by Alcan, the Canadian aluminium producing unit of Australiabased Rio Tinto. Oman Oil Company and the Abu Dhabi Electricity and Water Authority each hold a 40% stake in the project. Sohar is one of only three aluminium producers in the Gulf Arab region. 70 minutes costs Rio Tinto US$95,800 penalty A securities watchdog has collected an Australian $100,000 (US$95,800) fine from Rio Tinto, which was found to be 70 minutes tardy in disclosing last year’s US$38.1bn acquisition of aluminium producer Alcan Inc. The Australian Securities and Investments Commission (ASIC) said Rio Tinto failed to comply with disclosure provisions by not immediately notifying the Australian Securities Exchange (ASX) of certain information about the acquisition. According to the infringement ruling, at 2.30 p.m. (Australian eastern standard time) on 12 July 2007, Rio Tinto was aware it had made an offer 78 UC Rusal, the world’s largest aluminium and alumina producer, and Ust-Luga Company, the developer of Ust-Luga trade sea port, signed a memorandum of cooperation to construct a trans-shipment complex. The complex will consist of two terminals designed to transport aluminium and alumina at Ust-Luga trade sea port located in Leningrad oblast. UC Rusal will invest over US$300m in the project. The parties plan to launch the complex by 2011 with an initial shipment capacity of 2.5m tonnes of alumina and 2m tonnes of aluminium. The capacity of the trans-shipment complex could be further increased to 4.5m tonnes of alumina and 3.5m tonnes of aluminium. Century breaks ground for Iceland smelter Century Aluminum Co.’s wholly owned Nordural Helguvik unit broke ground at the weekend on a new aluminium smelter near Helguvik, Iceland. The Monterey, California-based aluminium producer plans to build a 250,000 tpy primary aluminium smelter in stages. The company expects the first stage of roughly 150,000 tpy to be online by late 2010. Century signed an MoU in June 2006 securing power for the smelter. Hitaveita Su- durnesja hf will supply 150 MW of the 250 MW required for the first phase, while Orkuveita Reykjavikur will supply up to 100 MW. The memorandum provides for an eventual total of 435 MW, enough to support 250,000 tpy of production. CBA aims for 570,000 tpy aluminium output in 2009 Brazil’s Companhia Brasileira do Aluminio (CBA), part of the Votorantim Group, plans to expand its primary aluminium production to around 570,000 tpy by 2009. This represents a capacity increase of over 20% compared with 2007. CBA will invest some 1.5bn Reais (US$918m) in 2008 for mining and electric power projects, as well as for resources at the company’s aluminium plant located in the municipality of Alumínio, in São Paulo state. Construction work to expand primary aluminium output at the São Paulo plant is already under way, providing room for 280 furnaces. Anglesey smelter at one-third capacity after fire The Anglesey aluminium smelter in Wales in the UK was closed in the night of June 12 by a serious fire, which started in a transformer and ignited 40,000 liters of oil. The fire, which caused widespread disruption around the smelter site, was extinguished after three hours. The smelter is operating at one third of its total capacity of 148,000 tpy due to safety and operational reasons after the fire, and it will take an estimated three months to restore production to full capacity. In the first potline, 106 cells out of 155 are operating, and the company is working to stabilise them, but the 155 cells in the second are completely shut. Doubts arose already over the future of Anglesey Aluminium Metal, owned by Rio Tinto and Kaiser Aluminium & Chemical, when the closure in 2010 was announced for the Wylfa nuclear power station in Holyhead that supplies the smelter. At the time ALUMINIUM · 7-8/2008 CO M PA N Y N E W S W O R L D W I D E the company was seeking to secure long-term energy supplies in order to keep the plant in operation. Argentina’s Aluar ramps up expanded capacity Argentine aluminium producer Aluar has started up the final batch of 24 pots associated with the Phase I expansion of its Puerto Madryn smelter. The upgrade and expansion of the plant, costing US$850m, will lift capacity by 137,000tpy to 410,000tpy. The final cells are expected to be fully operational within the next 30 days. station and thermal energy fired by Nigerian gas from the planned West Africa Gas Pipeline. The cross-border pipeline’s opening has been repeatedly delayed and is now expected in the next couple of months. Valco would smelt imported alumina, as it did previously, until the bauxite mine and refinery were ready. The smelter would be retrofitted to achieve optimum output. Rio Tinto, which mines 1m tpy of bauxite from Ghana’s only active bauxite operation, exports the ore directly overseas for refining. Alcoa will temporarily idle half the production at its Rockdale, Texas aluminium smelter effective 19 June as a result of ongoing supply issues with Luminant’s onsite power generating unit, Sandow Unit 4, and the resulting market power prices being uneconomical. Three of the plant’s six operating potlines will be idled beginning immediately as a result of the ongoing supply interruptions and of local market energy costs, which increased to as much as US$2,000-4,000 per MWh during peak hours. The idled potlines represent approximately 120,000 tpy year of production. Output at the remaining three potlines will continue using contracted long-term power. There are plans for a rod, wire and cable plant as well as a facility that will produce wheel alloys, car wheels and rims. The operation will use technology and labour from the China National Machinery & Equipment Import & Export Corp. (CMEC) to build the US$540m aluminium complex. The government will pay the remaining US$140m for the project. In some ways, Trinidad is an ideal location for an aluminium smelter. The country has ample fuel supplies. It is the leading supplier of liquid natural gas to the United States and the second-largest energy producer in the Caribbean after Venezuela, and there are several multiple deepwater ports available to import raw materials and export product. The Chinese government has been investing heavily in Trinidad recently. The two governments agreed to establish a joint committee for trade and other economic and technical cooperation initiatives, such as an interest-free loan for a US$60m linear accelerator X-ray scanning and radiation detection system at the country’s ports. Several major aluminium producers have tried to build smelters, but until now have been largely thwarted by a stalwart environmental lobby. The same environmental groups that frustrated Alcoa’s efforts have also filed litigation to revoke Alutrint’s certificate of environmental clearance. China credit helps Trinidad fund smelter Greenland Parliament supports Alcoa’s smelter project With US$400m in Chinese funding, Alutrint Ltd. is building a 125,000 tpy aluminium smelter in Trinidad and Tobago. Alutrint, the Trinidad and Tobago government-controlled aluminium smelter project, reached a US$400m credit agreement with the Export-Import Bank of China to fund the smelter near La Brea in southern Trinidad. Alutrint is 60% owned by the National Energy Corp. of Trinidad and Tobago Ltd. The remaining 40% is held by Sural CA, Caracas, Venezuela, which will act as the project’s downstream joint-venture partner. Alcoa welcomed the decision taken by the Greenland parliament to advance into a second phase of joint studies with Alcoa into the feasibility of establishing a world-class sustainable aluminium industry in Greenland. The parliament strongly endorsed Greenland Home Rule government’s recommendation that the proposed 340,000 tpy smelter should be sited at Maniitsoq, and it allocated significant funding to support the joint studies. These studies, which will extend through 2009, will develop in detail into the economic, social and environmental aspects of the © Alcoa to temporarily idle half of Rockdale, Texas smelter Rio Tinto Alcan mulls Libya or Algeria for aluminium smelter Rio Tinto is considering building an aluminium smelter in Libya or Algeria to take advantage of those countries’ natural gas supplies. The plan for building a greenfield plant in either country is only at a very early stage. Suggestions that the smelter would have capacity of 360,000 tpy are “speculative”, noting that the standard size of a smelter using Rio’s AP technology would be 360,000 tpy. Ghana bought Alcoa’s stake in Valco smelter Ghana’s government has bought Alcoa’s stake in the inactive 200,000 tpy Valco aluminium smelter and plans to relaunch the industry with a new bauxite mine and alumina refinery. The government paid Alcoa US$2m for its 10% stake in Valco, whose smelter has been shut since March 2007 due to low water levels in the Volta dam which powers it. The deal, giving the African state full ownership of Valco, was concluded in June. The Government has proposed a concept of an integrated aluminium industry in which the country’s bauxite will be mined, refined and processed to near-end or end products in Ghana. The government planned to restart Valco within the next year or so using a combination of power from Lake Volta’s Akasombo hydropower ALUMINIUM · 7-8/2008 79 CO M PA N Y N E W S W O R L D W I D E proposed facility. The parliament is expected to convene again in 2009 to consider Greenland’s ownership position in this project. The proposed smelter would combine Greenland’s abundant renewable hydropower potential with Alcoa’s experience in developing and operating aluminium smelters around the world in a manner that is sustainable, sensitive to the environment and valued by the communities in which the company operates. If feasibility is proven, production at the new smelter would be anticipated to begin 2014/2015 Nalco secures land and energy for Iran smelter project India’s National Aluminium Co (Nalco) has been allocated land and energy for its proposed 310,000 tpy aluminium smelter in Iran. Having the infrastructure ready for a greenfield smelter would reduce by nearly two agreement with the government of Queensland in March 2007, and in May 2007 agreed on land use with the natives of the Aurukun community. With the two agreements, the company won the mining license issued by Queensland in September. The Aurukun bauxite resources amount to about 420m tonnes. Chinalco plans to build a bauxite mine capable of realizing 10m tpy and an alumina plant with a production capacity of 2.1m tpy. The company also pledged environmental protection and energy conservation. years the gestation period of such projects, which is usually five years. The US$1.7bn smelter is to be built in two phases and Nalco will majority ownership in joint venture with a local partner. The pre-feasibility report for the smelter should be ready in about eight months. JSW plans aluminium smelter in Chhattisgarh JSW Aluminium plans to put up a 1m tpy aluminium smelter in Chhattisgarh. The smelter will be located near Jindal Steel and Power, another JSW company, and will be built in three phases of around 330,000 tpy each. A feasibility study has been launched to assess the project. The Chhattisgarh state government has allocated the land required for the smelter, which has also been alloted a coal block to support a 2,000 MW captive power plant. N China’s coal ash-to-alumina production line operational in 2009 China’s first coal ash-to-alumina production line should start up in 2009 in North China’s Inner Mongolian Autonomous Region. The production line will extract alumina from coal ash containing more than 40% of alumina. With an investment of 1.863 bn yuan, the production line is expected to produce 400,000 tpy of alumina, and consume 1.6m tpy of coal ash. According to industrial experts, industrialized coal ash-to- alumina production will help ease China’s aluminium ore shortage, cut coal ash waste and solve an environmental pollution problem. Bauxite and alumina activities AOS Yunnan Aluminium to build 800,000 tpy refinery in Wenshan Chalco’s 880,000 tpy alumina expansion complete by end-June Chinalco to start constructing Australian project next year Aluminium Corp. of China (Chalco) will commission a new 880,000 tpy alumina refinery at its Pingguo plant in southern China by the end of June. Half of the new capacity has actually been on stream since the end of May, and the remaining 440,000 tpy was commissioned at the end of June. The Pingguo plant, in China’s Guangxi autonomous region, already has over 900,000 tpy of alumina refining capacity and its alumina output reached 965,000 tonnes in 2007. Chinalco hopes to begin construction of the Aurukun bauxite mining project in Australia’s northeastern state of Queensland at the end of 2009. With a planned investment of A$3bn (about US$2.8bn), the mining project, owned by Chinalco’s aluminium subsidiary Chalco, is the largest investment deal by a Chinese company in Australia. A two-year feasibility study on the bauxite project started at the end of 2007 in parallel with an environment evaluation. Chinalco signed a mining 80 Yunnan Aluminium will start construction in June 2008 of its 800,000 tpy alumina refinery project at its subsidiary Wenshan Aluminium in Wenshan country, Yunnan province, and the refinery should come on stream by the end of 2009. This project includes auxiliary projects such as a 200,000 tpy caustic soda plant and 250,000 tpy of PVC production. The total investment is estimated at over 4bn yuan (US$577m). Yunnan Aluminium is also considering building a 400,000 tpy aluminium smelter and a semis plant around the alumina project in Wenshan Aluminium, but the exact schedule has yet to be determined. Wenshan ALUMINIUM · 7-8/2008 CO M PA N Y N E W S W O R L D W I D E Aluminium, located in southwestern China, is 55% owned by Yunnan Aluminium. The other investors include Yunnan Metallurgy & Construction Corp, Wenshan Dounan Manganese Co, and a local investment company. Chalco partly-owned alumina plant starts full run Guangxi Huayin Aluminium, 33% owned by Chalco, started full operations at a 1.6m tpy alumina refinery in June 2008. Increased output will depress prices in an already weak domestic alumina market, which spurred Chalco to slash alumina spot prices 17% in June in its first such reduction since December. The Huayin capacity was only the first phase of a planned 3.2m tpy alumina complex in Debao county in Baise city. The construction of the second refinery phase, with equal capacity, would depend on shareholders of Huayin. The first phase cost Huayin more than 8.3bn yuan (US$1.21bn). Rio Tinto plans new bauxite mine at Weipa to double output Rio Tinto has approved a US$30m feasibility study to develop a new bauxite operation to the south of its existing Weipa bauxite mine and port in Australia. This move would almost double output at the mine, and is the first step towards significantly expanding Rio’s operations at Weipa in Cape York, Queensland. The new operation would increase Weipa’s bauxite production to 35m tpy, from 18.2m tonnes in 2007, to increase supply to customers as well as Rio-owned refineries. In addition to the new mine, the feasibility study will also envisage of a new port and stockpile facilities worth about US$400m. The mine would take three years to build, with first production expected in early 2013. It has an estimated capital cost of about US$1bn including port costs, a transport system, power station, a beneficiation plant and operation support infrastructure. The feasibility study and environment impact study for mine development on the existing mine lease south of the Weipa ALUMINIUM · 7-8/2008 peninsula will take one to two years. The development would eventually replace the existing east Weipa mine and would provide a platform for further development of the large bauxite reserves and resources in the region. The project will be subject to government and environmental approvals. Weipa bauxite reserves at the end of 2007 were 1.22bn tonnes with resources of 2.22bn tonnes. China may cut alumina output as price declines Alumina producers in China, the world’s largest consumer of aluminium, may cut production soon in a bid to curb a price decline. Some refiners lowered the cash price of alumina to 3,200 yuan (US$465) a tonne. Chalco cut the price 17% to 3,500 yuan per tonne early in June. Alumina production in China has outpaced demand this year, forcing Chalco and Shandong Chiping Xinfa Group to cut prices. In the first five months over a year before China boosted output 18%. The marginal cost of refineries in Shandong using imported bauxite could be as high as 3,300 yuan a tonne. The price decline will force refineries suspend production or to reduce output in the coming weeks. New alumina projects that started production in 2008 include the 1.6m tpy Guangxi Huayin project, the 400,000 tpy Shanxi Yangquan project and the 800,000 tpy Guangxi Chiping project. Alcoa agreement with Vietnam on raw material projects Alcoa signed a cooperation agreement with Vietnam’s premier minerals development company, Vietnam National Coal-Mineral Industries Group (Vinacomin), for cooperation in the development of the aluminium industry in Vietnam. Under the agreement, Alcoa World Alumina and Chemicals (AWAC) will conduct due diligence, on the acquisition of a 40% interest in the 600,000 tpy Nhan Co alumina refinery that is to be constructed in Dak Nong Province in Vietnam’s Central Highlands, based on access to extensive reserves of high quality bauxite. If the transaction proceeds, the shareholding in the Joint Stock Company that owns the Nhan Co bauxite mine and alumina refinery will be Vinacomin 51%, AWAC 40% and other investors 9%. In addition the parties have agreed to conduct a joint feasibility study on the Gia Nghia bauxite mine and alumina refinery project, also located in Dak Nong province, with first stage capacity expected to be between 1.0 and 1.5m tpy of alumina. The agreement follows the recent permission granted to Vinacomin by the Government of Vietnam to establish Joint Stock Companies with foreign partners holding a maximum of 40%. Vinacomin is a state-owned company with a leading role in the development of Vietnam’s mineral resources. AWAC and Vinacomin will now embark on detailed studies with a view to completing definitive costs and definitive investment agreements as quickly as possible. Rich Angola plans 3m tpy Bissau bauxite mine Angola is developing a US$500m project to mine 3m tpy of bauxite. The mine would be the single biggest foreign investment in one of the world’s poorest states, with a history of political instability since independence from Portugal in 1974. Angola Bauxite, part-owned by the Angolan state, paid an up-front fee of US$13m to Guinea-Bissau in September 2007 for a leased mining concession in the southeastern Boe region. The Boe deposits are a continuation across the thickly forested border of huge bauxite reserves in neighbouring Guinea. The Angolan company will seek to develop reserves in Guinea-Bissau calculated at 110m tonnes, containing 44% aluminium oxide. The US$500m investment will include exploitation of bauxite, the construction of the port of Buba, and a railway and road linking Boe and Buba. The Brazilian company Asperbras helped with the studies. Precise startup dates still have to be defined.

Sohar Industrial Port Co will be responsible for operating and developing the plant under a partnership agreement between the Oman government and the port of Rotterdam. The deciding factor for the investment was the plant’s strategic location at Sohar outside the Strait of Hormuz, from where the company will supply downstream aluminium products to the emerging markets of India and Africa. Molten Aluminum opens US$16m plant next to Honda 82 Mil-Ver Metals lights up new furnace Mil-Ver Metals, the UK-based aluminium ingot producer, started its new 18-tonne furnace this week as part of the continuing expansion of its secondary aluminium plant. The furnace will use energy more efficiently rather than boost capacity. Mil-Ver now has the flexibility and efficiency required to fully maximize yields when melting all aluminium grades. Mil-Ver, a wholly owned subsidiary of Amalgamated Metal Corp (AMC), is one of the UK’s largest smelters with a capacity in excess of 25,000 tpy. N Aluminium semis Hydro Molten Aluminum Producer Canada Inc. (Mapcan) opened a US$16m aluminium plant in Alliston, Ontario, that will supply Honda’s soon-to-beopened engine plant across the street. The plant has the capacity to produce 50,000 tpy of aluminium made from recycled scrap. About 20% of the metal will be used at the neighboring Honda of Canada Mfg. engine plant, which is scheduled to open in September. The rest will be shipped to other Honda affiliates in the United States. The company claims it will be the first plant in North America to offer molten aluminium directly to die-cast machines.

Bangalore-based Future Metals Private Ltd will have a 70% stake in the new joint venture, while the rest will be owned by Takamul Investment, a venture capital fund set up by Oman Oil Company (OOC), a state-owned energy investment company. The agreement covers the establishment of an aluminium rod extrusion plant at the Sohar Industrial Estate using hot metal from Sohar Aluminium’s newly operational US$2.4bn smelter. Oman is developing a downstream aluminium park within Sohar, which is earmarked exclusively for projects that will utilise hot metal from the giant smelter. Sohar Aluminium has pledged up to 60% of its total liquid metal output of its 350,000 tpy for downstream industries. Novelis Korea offers multialloy aluminium sheet products Novelis Korea Ltd. has successfully completed the installation of Novelis Fusion technology at its plant in Ulsan, South Korea, and has begun commercial production of multi-alloy aluminium sheet products. This is Novelis’ second application of its proprietary technology following the ground-breaking launch at its plant in Oswego, New York, in 2006. This is also Novelis’ second major investment in South Korea this year after the completion of a US$30m expansion of its aluminium rolling mill in Yeongju in March 2007. Installing the technology in the Ulsan plant involved reconfiguring the existing ingot casting facility, known as the Universal Casting Shop. As its name implies, the casting shop has a flexible configuration which can be easily adapted to different casting technologies, making the conversion 84 to Novelis Fusion rapid and cost-efficient. The casting facility is now producing both Netcast shape-cast products for automotive parts and Novelis Fusion ingots for sheet products. The initial opportunity for Novelis Fusion sheet products in the Korean marketplace is to replace the conventional clad aluminium products used in heat exchanger applications. Novelis has already begun to supply brazing sheet to Korean customers that previously relied on imports, and the company expects to continue to increase its market share in the Asian market. According to Novelis, the response from customers is positive, and the company is rolling out its Fusion technology worldwide. Projects are under way to also install the technology in Sierre, Switzerland, and in Pindamonhangaba, Brazil, which will provide global coverage to all major markets. ASIA Rio Tinto Alcan opens packaging plant in India Rio Tinto Alcan has opened a new flexible packaging plant in Haridwar in northern India.

This also expands Alcan’s presence in emerging markets overall, which today represent approx. 20% of its sales. The new plant is dedicated to producing high-value flexible packaging for the food and personal care segments in India. Including the plant in northern India, Alcan Packaging now operates 15 facilities in six countries. N Suppliers UC Rusal successfully tests new environmentally efficient aluminium production technology UC Rusal successfully launched test production of the key component of a unique and environmentally sound aluminium production technology – colloidal anode paste. The total investment in this project will amount to US$25m. Developed by the UC Rusal Engineering and Construction Division, the main goal of this project is an ideal Søderberg reduction cell, which minimises environmental impact and the consumption of raw materials. Through a number of technological and technical innovations, it will enable Søderberg technology to achieve the efficiency and ecological parameters of the alternative prebake technology. In April 2008, test production of colloidal paste was started. Meanwhile, 20 Søderberg reduction cells at the Krasnoyarsk smelter use colloidal anode paste. When the testing is completed, the technology will be implemented in a whole potroom at the smelter, and later it will be rolled out across five potrooms. In the pe- riod 2010 to 2015, the technology will be introduced at all UC Rusal smelters that use Søderberg technology. When this unique technology is introduced at the Krasnoyarsk smelter, the hydrofluoric emissions will be cut to 0.24 kg per tonne (from 0.7 kg per tonne previously), fluorine emissions to 0.6 kg per tonne (from 1.62 kg per tonne), CO2 emissions to 53.5 kg per tonne (from 78.9 kg per tonne), benzo(a)pyrene emissions to 0.001 kg per tonne (from 0.002 kg per tonne tonne). The benzo(a)pyrene emissions levels will meet the requirements of the Russian laws and recommendations of Ospar 2010.

Developed by Rio Tinto Alcan’s Arvida Research and Development Centre, the technology will also enable the plant to treat potlining from other Quebec aluminium producers. Tomorrow Technology supplies anode slotting machine Buss CP kneaders: single-source again In October 2007, Corus Aluminium Voerde GmbH in Germany awarded Tomorrow Technology (TT) from Italy with a contract to supply an automatic carbon anode slotting machine, including the required anode conveying lines. The ordered equipment has to be integrated into the existing anode supply chain with minimal interruption of the ongoing anode rodding production. Many smelters are now converting to slotted carbon anodes, which allow CO2 gas bubbles to escape faster from under the anodes, thus improving the reduction process performance due to lower voltage drops and improved reduction cell stability. The equipment supplied by TT is designed to cut two longitudinal slots for the Voerde anode as well as to cut single or double slots for external customers. With the supply of this anode slotting machine TT is completing its range of equipments dedicated to anode production, such as anode and stub hole cleaning, anode handling devices and roller conveyors. As of 1 August 2008 Buss AG of Pratteln, Switzerland will be marketing its large CP kneaders on its own again. That is when a ten-year marketing agreement with Buss ChemTech AG in Pratteln ends. During this time Buss AG continued manufacturing the CP kneader, used for anode paste compounding in electrolytic aluminium production, and improved it both from the mechanical and process technology points of view. Buss AG was also responsible on behalf of its marketing partner for CP Kneader spares and replacements as well as local service. All the leading aluminium producers worldwide use Buss kneaders today – currently at least 200 of them for anode paste processing. Rio Tinto Alcan opens spent potlining pilot plant Rio Tinto Alcan has officially inaugurated its newly commissioned pilot plant for the treatment of spent potlining, in Saguenay, Quebec. Spent potlining is a material that is removed periodically from the electrolytic cells used to produce aluminium.

N Seco/Warwick Installation of a travelling homogenizing furnace at Miluo Longzhou Aluminium completed floor space, since the furnace moves from one loading area laterally to the second loading area. • Loading and unloading consideration: a travelling furnace load base is floor level and the load base can be loaded or stacked with a fork truck. The loading base is designed with steel cover plates to withstand not only the billet load, but also the weight of the fork truck. Fork trucks can be used because overhead cranes are not Seco / Warwick Seco/Warwick (Tianjin) Industrial furnace Co. Ltd. has recently completed the installation of a travelling homogenizing furnace at Miluo Longzhou Aluminium Co. Ltd., a specialty aluminium alloy billets manufacturer in China. The company operates a 50 kt/a recycling aluminium alloy billet production line, which can produce 6000, 7000 and 2000 series of 152 mm, 178 mm, 254 mm diameter extrusion aluminium alloy billets. Travelling homogenizing furnace The furnace offers several advantages: • Limited plant floor space: the utilization of the travelling furnace provides twice the loading area in half the 86 needed. The potential of a billet rolling off an above floor level load car is reduced. The loading and unloading of the billet bases is accomplished in less time. Placing thermocouples in the load is made easier since the load is at floor level. • Energy savings: with the conventional car bottom type of furnaces, the load car is removed from the furnace, unloaded and then reloaded, and is then driven back into the furnace. During this time, the furnace interior can lose a significant amount of heat, so to bring the furnace back up to temperature will take additional time and heat input. • Cycle time reduction: when the new travelling furnace has completed the cycle, the furnace doors open and the furnace travels from one loading base to the next. The first base can be cooled, and then re-loaded while the other load is under heat. The result is a faster load change with a reduced heat loss from the furnace. Once the furnace has moved into position on the adjacent load base, the heating cycle begins. With the travelling furnace design, a reduction in overall heating time and input can be accomplished, compared with car furnace designs. Technical details: • Billet material specifications: batch load capacity – 60 tonnes maximum; billet diameters – 152 mm, 178 mm, 254 mm; billet length – 6800 mm • Furnace specifications: furnace design temperature – 650°C; furnace operating temperature – 570 to 580°C • Load temperature uniformity: +/- 5°C N ALUMINIUM · 7-8/2008 RESEARCH B4C-Al and B4C-TiB2-Al composites reactively bonded with AlMgB14 formed in situ V. Kevorkijan, Maribor Macro-hardness is one of the most valuable engineering properties of pressurelessly sintered boron carbide, particularly in lightweight armour systems and for various wear resistant engineering applications [1]. However, to ensure superior macrohardness (approx. 32 to 37 GPa) in pressurelessly sintered boron carbide, the sintering process should be carried out typically at temperatures higher than 2000°C, which substantially increases the production cost. The cost-effective alternatives are various B4C-based composites, among which B4C-Al metal matrix composites (MMCs) have been particularly well investigated [2-5]. B4C-Al composites are a family of engineering materials in which a range of properties can be developed, combining the high rigidity and hardness of B4C with the ductility of aluminium. Moreover, the Al-B-C system enables the creation of an entire spectrum of low-temperature (Al3BC, AlB2) and high- temperature (AlB12C2, Al4C3) phases, making it possible to tailor the composition and microstructure of the multiphase material accurately. Due to the several great advantages they combine, B4C-Al composites are the material of choice in many applications such as armour plate with high ballistic efficiency, disk drive actuators, hard disk substrates, brakes with high wear resistance, etc. First of all, B4C-Al composites need approx. 40% less B4C powder than presurelessly sintered (or hot pressed) B4C and can be fabricated at relatively low temperatures (1100°C), in an inert atmosphere at atmospheric pressure. The most frequently practised fabrication method is spontaneous, reactive infiltration of molten aluminium alloy into a porous B4C compact. The infiltration proceeds very rapidly (minutes), even for thick preforms (25 cm thick). As a result, in just one single processing step, near-net shape products could be fabricated with high productivity.

The mechanism of formation of the AlMgB14 bonding phase is also discussed. Experimental Two classes of composites: reactively infiltrated B4C-Al and B4C-TiB2-Al, as well as reactively bonded B4C-Al and B4C-TiB2-Al with AlMgB14, were prepared by melt infiltrating 2024 Al alloy blocks into isostatically pressed preforms under an argon atmosphere. In the case of the reactively infiltrated composites, two types of preforms were fabricated. Type A preforms for B4C-Al composites were made from commercial B4C powders (H. C. Starck; Grade HD 07). In addition, preforms of type B for B4C-TiB2Al composites were made using the same B4C powder as for type A, doped with 30 wt% of TiB2 powder (H. C. Starck; Grade D). Preforms (types C and D) for reactively bonded composites were made from the same B4C and TiB2 powders as types A and B. However, to enable formation of the AlMgB14 bonding phase, preforms C, D1, D2 and D3 contained different amounts of MgB2 (H. C. Starck; Grade A) and amorphous B (H. C. Starck; Grade I) powders. The initial composition of the preforms used in this work is listed in Table 1. In order to improve the wetting of boron carbide with molten aluminium, chemical pretreatment of the as-received powders was carried out. The pretreatment consisted of chemical cleaning of the boron carbide powders in an equimolar mixture of HF and H2SO4 for 5 min, air drying at room temperature for 6 h, additional drying at 150°C for 24 h and calcination at 400°C for 3h, both in an Ar atmosphere. The mixture of pre-treated boron carbide powders and other reactants was homogenized and isostatically pressed at 200 MPa to produce samples with a green density from 70 to 78% T.D. Typically, the preforms consisted of 70 wt% of B4C and 30 wt% of other additives. Prior to the infiltration process, the preforms were passivated by heattreating them in the absence of free carbon at 1450°C for 2 hours under 88 an argon atmosphere. For infiltration, the preform was put into a sintered boron-carbide crucible, the aluminium compact was placed on top of the preform at room temperature and infiltration was carried out at the desired temperature in a static argon atmosphere. The infiltration temperatures were chosen as 1100°, 1200°, 1300° and 1350°C, while the holding time was 30 or 60 min. Heating and cooling rates were 20°C/min. After infiltration, the assembly was cooled to about 600°C in an argon atmosphere in order to inhibit oxidation during solidification, and removed from the furnace. The densities of the infiltrated preforms were determined using the Archimedes principle. Their microstructure was examined by optical and scanning electron microscopy (SEM). The reaction products were analysed using an EDS detector. The Vickers micro-hardness and Vickers hardness of infiltrated and polished (down to 1 μm) samples were measured using a Fischerscope H100C micro-hardness tester and a Wilson Tukon Vickers macro-tester with a load of 1000 g, respectively. Five different measurements were made for each sample. X-ray powder diffraction patterns were collected on a Bruker D4 diffractometer using Cu Kα radiation in the range from 10 to 60° 2θ. Phase analysis was done with the help of Crystallographica Search-Match software [6] using the PDF-2 database release 2004 [7], while quantitative phase analysis was carried out using the Rietveld method, with the Topas proInfiltration conditions 1100 1100 1200 1200 1300 1300 1350 1350 Results In Tables 2 to 6 the phase content and measured Vickers macro-hard- Phase composition of infiltrated samples (wt%) Temperature Time (°C) (min) 1 2 3 4 5 6 7 8 gram [8]. The structural data were obtained from the ICSD [9]. To account for the differences in the absorption coefficients of the phases present, the Brindley [10,11] correction was applied. The particle diameter was set to 1 μm as determined from the SEM image of the microstructure of the material. Phase quantification was done in two steps. In the first, the mass ratio of the phases identified was determined from the Rietveld refinement of the pattern of powdered as-made material. In the second, the samples were mixed with a known amount (40.0 wt%) of corundum with a particle size of 1μm and the data collection and refinement were repeated. Due to the presence of material not included in the Rietveld refinement model (amorphous or non-identified crystalline phases), the calculated wt% of corundum was in all cases larger than 40.0%. Dividing the actual (40.0%) by the calculated value of the wt% of corundum, a factor was determined which was used to multiply the relative weight fractions of the crystalline phases identified, derived in the first step, to obtain the ‘absolute’ weight fractions. The Rwp factors of the refined patterns were in the range between 13 and 15%. Cross-checking between the as-made and corundumadded samples showed good agreement and it was estimated that the errors in the quantitative phase analysis did not exceed 5% relative. 30 60 30 60 30 60 30 60 Vickers hardness (GPa) B4C Al AlB2 Al3BC AlB12C2 36 28 35 24 33 12 25 6 15 14 14 5 7 4 6 4 6 8 6 10 13 6 13 5 41 47 42 57 43 72 49 77 2 3 3 4 4 6 7 8 11.8 ± 0.4 10.9 ± 0.3 11.8 ± 0.4 11.0 ± 0.3 12.0 ± 0.4 9.7 ± 0.3 11.4 ± 0.4 7.9 ± 0.3 Table 2: Phase composition and Vickers hardness of B4C-Al composites made by infiltration of preform A ALUMINIUM · 7-8/2008 RESEARCH ness of both B4C-Al composites prepared in the laboratory and reactively infiltrated, reactively bonded B4C-Al composites are reported. As evident, unreacted B4C and Al, and the reaction products AlB2, Al3BC and AlB12C2 were present in almost all the samples of both reactively infiltrated and reactively bonded composites, the amount depending on the infiltration conditions. In addition, in the reactive bonded composites, the AlMgB14 bonding phase was formed from MgB2 and boron under all experimental conditions, whereas TiB2 particles added to the starting reaction mixture remained chemically inert. Moreover, in the reactively bonded composites, a small amount of MgAlO4 was also detected in samples infiltrated at higher temperatures. The AlB2 phase varied between 2 and 13 wt%, with the amount generally decreasing with increasing infiltration temperature. An exception was the system B4C-Al in which, on increasing the infiltration temperature, the amount of AlB2 phase passed through a twin-peak maximum at 1300° and 1350°C. The appearance of Al4C3 phase was not detected either in reactively infiltrated or in reactively bonded samples. The AlB12C2 phase was detected in all the infiltrated samples. Its amount varied between 2 and 8 wt%, generally increasing with depletion of the initial boron carbide content. The highest amount of AlB12C2 was obtained by infiltration at 1350°C for 60 min. (Table 2). The same results were obtained in reactively bonded samples with the same initial B4C content (Table 3). However, in samples where the initial B4C content was lower due to the addition of TiB2 (Tables 4, 5 and 6), the amount of AlB12C2 phase produced under the same experimental conditions was drastically reduced. Al3BC was found to be one of the main reaction products in all laboratory-prepared composites since boron carbide was the dominant constituent in the preforms (Tables 2, 3 and 4). In contrast, in preforms with a low boron carbide content (Tables 5 and 6), the final amount of Al3BC become even Infiltration conditions 1 2 3 4 5 6 7 8 comparable with the free aluminium content. The quantity of AlMgB14 bonding phase in the samples was changed systematically (starting from about 20 wt%, (Tables 3 and 4), to ~40 wt%, (Table 5), and around 60 wt%, (Table 6) by adjusting the concentration of MgB2 and boron in the porous preforms. The chemical conversion of MgB2 and boron to AlMgB14 bonding phase was found to proceed completely. A small amount of spinel phase (MgAlO4) was also formed but never exceeded 4 wt% in the temperature and time intervals investigated. According to SEM/EDS and RTG, no residual MgB2 and elementary boron were detected in the composites after infiltration and bonding under the processing conditions investigated. The Vickers micro- and macrohardness of all the prepared composite samples were measured and correlated with the initial chemical composition of the porous preforms, as well as the processing conditions.

Vickers micro-hardness of the various phases detected in laboratory samples after infiltration and bonding are summarized in Table 7. As expected, the least hard phase is TiB2 and the hardness order is B4C > AlMgB14 > AlB12C2 > Al3BC >AlB2 >Al. The experimentally determined Vickers macro-hardness values are presented in Tables 2 to 6. The measured values of the Vickers macro-hardness of laboratory-prepared composites were in the interval between 7.9 and 28.7 GPa. The highest values of macro-hardness (approx. 90% of the macro-hardness of presurelessly sintered boron-carbide) were found in samples with 30 wt% TiB2 reactively bonded to approx. 60 wt% of AlMgB14. Fig. 1 shows the microstructure of a B4C-Al composite (Sample 1, Table 2) reactively bonded with AlMgB14. As is evident, B4C and Al3BC are the predominant phases isolated. Some traces of AlB2 and AlB12C2 were also detected. The residual aluminium and AlMgB14 bonding phases appear in the form of a continuous metallic matrix with AlMgB14 and AlMgB14+MgAl2O4 aggregates. The microstructure of the B4C-TiB2Al composite (Sample 4, Table 4) reactively bonded with AlMgB14 consisted of an interpenetrating network of numerous individual phases (B4C, AlB2, Al3BC, AlB12C2, AlMgB14 and MgAl2O4) formed in situ, B4C and TiB2 particles, and a co-continuous network of residual aluminium, Fig.2.

Generally, all the microstructures obtained are very complex, with numerous phases formed in situ. Moreover, the spatial distribution, morphology, and connectivity of these phases vary markedly, resulting in their poor repeatability. Discussion Reactive infiltration of boron carbide with molten aluminium The phases formed during infiltration of a B4C preform with molten aluminium alloy are mainly Al3BC and AlB2, although several other phases (AlB12, AlB12C2, Al4C3) were also thermodynamically predicted. Between 600° and 700°C, AlB2 and B4C are the predominant phases. Above 700°C AlB2 and Al3BC are both present, and as the temperature increases the relative amount of Al3BC increases. Finally, between 900° and 1000°C, the predominant reaction product is Al3BC. The chemical changes occurring in the system below 1000°C could be summarized by the following chemical reaction: B4C + 3Al ↔ Al3BC + 3B(Al) (1) The elemental boron liberated by reaction (1) is finely dispersed in molten aluminium and could further react with Al forming AlB2: B(Al) + Al ↔ AlB2 (2) At about 1000°C, AlB2 decomposes and generates free aluminium. The infiltration of a B4C preform carried out above 1000°C produces mainly AlB12C2 and, after a longer infiltration time, some Al4C3. The formation of AlB12C2 is favoured by lowering the initial B4C powder particle size. When the formation of AlB12C2 begins, the consumption of B4C increases drastically: B4C 31,6 ±1,1 Al 3±0,1 3B4C + Al ↔ AlB12C2 + C(Al) (3) The elemental carbon liberated by reaction (3) and finely dispersed in molten aluminium further reacts with Al forming Al4C3: 3C(Al) + 4Al ↔ Al4C3 (4) However, this reaction proceeds slowly, so by using a shorter infiltration time (about 10 min) the formation of Al4C3 could be avoided almost completely. Due to the significant complexity of the system, several other chemical reactions could also occur. For example, both elemental boron and carbon finely dispersed in molten aluminium could react with Al4BC, transforming it into AlB12C2: Al3BC+11B(Al)+C(Al) ↔ AlB12C2+2Al (5) Mechanism of reactive bonding with AlMgB14 The mechanism of formation of AlMgB14 has been described elsewhere [12], but briefly, the formation of orthorhombic AlMgB14 is initiated by the formation of α-rhomohedral boron consisting of nearly regular B12 icosahedra in an approximately cubic close packed arrangement, with bonds between adjacent icosahedra. In addition, it seems that the presence of elemental boron at the reaction front is a prerequisite for successful formation of orthorhombic AlMgB14. Trials with AlB12 and MgB2 as reactants were unsuccessful, resulting in a maximum of 25 vol-% of AlMgB14 in the product mix. To achieve maximum AlMgB14 yield, a sufficient concentration of highly volatile reactants (particularly magnesium) at the reaction front should be ensured. In this respect, MgB2 enables the liberation of elemental magnesium in situ, at temperatures of about 1100° to 1400°C, depending on the overpressure in the reaction chamber. Under atmospheric pressure, the decomposition temperature of MgB2 is 1047°C: Vickers microhardnes (GPa ± S.D.) TiB2 AlB2 Al3BC AlB12C2 31,8±1,1 10,3±0,4 11,8±0,4 27,9±1,0 AlMgB14 29,4±1,0 Table 7: Vickers microhardness measured on isolated ceramic phases in infiltrated and reatively bonded composites ALUMINIUM · 7-8/2008 MgB2 = Mg + 2B (6) Thus, the overall reaction for the formation of AlMgB14 bonding phase could be written as: MgB2 + 12B + Al = AlMgB14 (7) Modelling the phase composition of B4C-Al composites reactively bonded with AlMgB14 for achieving maximum macro- hardness To achieve the maximum hardness of B4C-Al composites comparable with the hardness of pressurelessly sintered boron carbide, it is necessary to introduce the secondary bonding phase formed in situ, during spontaneous reactive infiltration of the green compact with molten aluminium. Among the various phases formed during reactive infiltration of boroncarbide with molten aluminium, the highest micro-hardness was measured for AlB12C2. The measured Vickers micro-hardness was in the range of 26 to 28 GPa, which is about 80% of the micro-hardness measured on B4C grains. However, the maximum amount of this phase in a B4C-Al composite experimentally achieved after detailed optimisation of the processing parameters was 8 wt%. Due to the presence of other phases formed during reactive infiltration (such as Al3BC and AlB2) and in addition a minimum of 4 wt % of solidified aluminium alloy, the hardness of low-temperature reactively fabricated, fully dense B4CAl composites was very poor (typically about 40-45% of the hardness of pressurelessly sintered boron carbide). An additional improvement was made by introducing a secondary bonding phase based on AlMgB14. The macro-hardness of well-optimized composites (Sample 8 in Table 1) was in the range of 60% of the hardness of pressurelessly sintered boron-carbide. In comparison with the macrohardness of B4C-Al composites, this was a 50% improvement but still not enough for armour applications. The reason for such a modest improvement lies in the fact that during reactive infiltration most of the boron carbide is transformed to Al3BC and AlB2 with micro-hardnesses of about one third of the micro-hardness of B4C. In other words, although during reactive © 91 RESEARCH infiltration and reactive bonding the hardness of the composite improved with about 36 wt% of new very hard phases, the boron-carbide phase was also almost completely transformed, unfortunately into phases with poor hardness. Further improvement of the hardness of low temperature reactively bonded B4C-Al composites is possible only by: (1) inhibiting the reactivity of boron carbide by covering its surface with various protective layers (e.g. hexagonal BN); or (2) replacing a significant portion of boron carbide with some other hard ceramic phase, which remains inert in contact with molten aluminium. In this paper, the second approach was investigated, by introducing 30 wt% of TiB2 particles. The result was a significant improvement in the macro-hardness of composites synthesized at 1100°C, to almost 78% of the hardness of pressurelessly sintered boron carbide. Conclusion Reactive bonding of carbides and borides with in situ formed AlMgB14 to achieve excellent hardness in combination with near-net shaping is a promising new method for the fabrication of complex ceramic structures for military and civil applications. Fully dense B4C-Al and B4C-TiB2-Al based composites, reactively bonded with AlMgB14 phase, were routinely fabricated by spontaneous infiltration of green compacts at temperatures of 1100° to 1400°C. The best macrohardness values (23-24.5 GPa, that is 70% of the macro-hardness of sintered boron carbide) were obtained at 1100°C, approximately 50% below the sintering temperature of B4C. Further improvement of macro-hardness is possible by increasing the volume fraction of TiB2. The new class of reactively bonded composites is particularly suitable for advanced, low-weight and cost-effective ceramic armour and various wearresistant engineering components.

N ALUMINIUM · 7-8/2008 EVENTS ALUMINIUM China 2008 – Nachlese Zur vierten Auflage der Fachmesse ALUMINIUM China zählte der Veranstalter Reed Exhibitions 6.744 Fachbesucher. Vom 28. bis zum 30. Mai 2008 präsentierten sich insgesamt 265 Aussteller aus 24 Nationen auf der Messe, die erstmals in Guangzhou in der südchinesischen Provinz Guangdong stattfand. Neben Branchengrößen wie Alcoa, Aleris, Novelis, Wagstaff und Fata Hunter nutzten zahlreiche chinesische Aussteller die Messe für ihre Präsentation: u. a. Chinalco, Asia Aluminium und Haomei. Mehr als 70 Aussteller kamen allein aus der südchinesischen Provinz Guangdong, der Provinz mit der höchsten Zahl an Industriebetrieben in China. Parallel zur Messe hatten die Besucher die Möglichkeit, an einer Reihe von organisierten Betriebsbesichtigungen im Großraum von Guangdong teilzunehmen. Zudem wurde die Messe erstmals vom „China Aluminium Fabrication Forum“ begleitet. Initiiert wurde die Konferenz von der China Non Ferrous Metal Industry Associa- tion und dem chinesischen BranchenBeratungsunternehmen Antaike, die beide zusammen seit Beginn auch die Messe unterstützen. Anzumerken bleibt, dass die Besucher- und Ausstellerzahlen dieses Jahr erstmals rückläufig waren. Es habe sich gezeigt, so ein Vertreter von Reed Exhibitions, dass viele Aussteller und Besucher den Standort Shanghai als Messeplatz favorisieren. Die nächste ALUMINIUM China (30. Juni bis 2.

Apelian, M. Makhlouf, Controlled diffusion solidification International Foundry Research / Giessereiforschung 60 (2008) No. 1, S. 30-36 conventionally cast alloys. In this publication, the process variables are explored and an operational window is established. In addition, the applicability of the CDS is demonstrated for commercial alloys. 12 figs., 7 tables, 4 sources. Wrought aluminum-based alloys exhibit superior physical and mechanical properties compared to conventional shape casting alloys. However, wrought alloys cannot be cast into near net shapes because they develop hot tears and hot cracks during solidification. For this reason, these alloys are typically cast into ingots and are subsequently brought to final shape by mechanical processes such as rolling, extrusion, drawing and forging. These processes significantly increase the cost of the manufactured component. Controlled Diffusion Solidification (CDS) is a novel process that allows casting of wrought alloys directly into final shapes that are free of hot tears, thus CDS eliminates the added cost of machining. The process follows a different mute from conventional casting methods. In CDS two liquid alloys of predetermined composition and temperature are mixed together so that upon solidification the resultant alloy has a globular rather than a dendritic microstructure. The hot tearing tendency of wrought alloys originates from the inadequate permeability of their dendritic network, which obstructs the flow of interdendritic liquid and hinders compensation for shrinkage. The nondendritic microstructure made possible by CDS minimizes hot-tearing thus enabling wrought alloys to be cast directly. A novel and easy to employ method has recently been devised to allow casting of wrought alloys. The method, which is referred to as “Controlled Diffusion Solidification (CDS)” relies on mixing two precursor liquid alloys of precisely controlled chemistry and temperature in order to produce a pre-determined alloy composition. The final temperature of the resultant alloy is aimed at a temperature that is a few degrees below the alloy’s liquidus temperature, and therefore contains some fraction solid that al-lows fast, copious nucleation of the solid phase from the liquid phase. Consequently, the resultant alloy solidifies over a short temperature range and has a non-dendritic microstructure that minimizes its tendency towards hot tearing and makes it more amenable to casting operations, rather than the predominantly dendritic microstructure that is typical of ALUMINIUM 7/8 (2008) ALUMINIUM · 7-8/2008 Werkstoffe, Legierungen D. Zander, U. Köster Influence of the casting method on microstructure and corrosion of magnesium alloys International Foundry Research / Giessereiforschung 60 (2008) No. 1, S. 38-43 Corrosion of thixomolded and die cast AZ91 and AM50 was investigated and discussed in regard to the microstructures involved. The investigations showed that the different behaviour can be explained by the influence of four microstructural aspects: porosity, volume fraction and distribution of the β-phase (Mg17Al12) and Al-content of the a-phase. In general, die cast AZ91 revealed a better corrosion behaviour regarding passivation and active dissolution in pH11 than in pH8 in comparison to AM50. The corrosion rates increased significantly with decreasing pH for both magnesium alloys which can be mainly related to the active dissolution of magnesium from the α-phase. In addition galvanic corrosion between the a-phase and the discontinuous distributed β-phase accelerates the corrosion. In alkaline solutions the corrosion rate of thixomolded AZ91 is one order of magnitude lower than of the die cast ones. The fine eutectic structure with the more noble continuous ß-phase works as a barrier against further corrosion attack as well as the formation of Mg(OH)2. Only small additions of 0.01 M NaCl lead to a change from passivation to active dissolution and pitting of thixomolded AZ91 in alkaline solutions. In addition a strong influence of the sampling point (gate, centre, overflow), the processed thickness of thixomolded AZ91 and therefore of the Al-content on the corrosion current density and rate was observed. 9 figs., 16 sources. ALUMINIUM 7/8 (2008) Magnesiumlegierungen © 99 LITERATURSERVICE O. Hahn, M. Wißling FEM-Simulation von mechanisch gefügten Verbindungen unter Crashbelastung Schweißen und Schneiden 60 (2008) Heft 3, S. 134-142 Der zunehmende Verdrängungswettbewerb auf stagnierenden Märkten, die Globalisierung bei der Vermarktung von Produkten und ein sich hieraus ergebender steigender Wettbewerbsdruck durch zusätzliche Mitbewerber zwingen insbesondere die Unternehmen in der Fahrzeugindustrie zur Erhöhung ihrer Produktivität. Daraus leitet sich die Forderung nach einer Verkürzung von Entwicklungszeiten für neue Fahrzeugmodelle ab. Dem stehen steigende Anforderungen an den Insassenschutz entgegen, insbesondere bezüglich der kosten- und zeitintensiven Crashsicherheitsbewertung. Diese Ausgangssituation bedingt den verstärkten Einsatz von rechnergestützten Berechnungsmethoden im Rahmen der konsequenten Umsetzung einer virtuellen Produktentwicklung. Mit Hilfe der FiniteElemente-Methode (FEM) kann das Fahrzeugverhalten unter Crashbelastung bereits in einem frühen Entwicklungsstadium abgeschätzt werden. Voraussetzung dafür sind zum einen experimentell ermittelte Werkstoff- und Verbindungskennwerte als Eingangsdaten für die Simulation und zum anderen geeignete numerische Methoden zur Berücksichtigung der Fügestellen in der Simulation. Im Rahmen dieses Beitrags werden Methoden zur experimentellen Kennwertermittlung und ein praxisgerechter Berechnungsansatz zur Auslegung mechanisch gefügter Verbindungen unter Crashbelastung vorgestellt. 11 Abb., 1 Tab., 19 Qu.

Lukác, Short fibres and particles impact on compressive behaviour of an AZ91 alloy International Foundry Research / Giessereiforschung 60 (2008) No. 1, S. 44-52 The influence of various reinforcement types and preparation routes on the physical and mechanical properties of the AZ91 magnesium alloy has been investigated in this complex study. Compression tests were carried out at temperatures between 20 and 300°C The volume fraction, shape and composition of the reinforcements significantly influence the microstructure and the properties of a composite. Different contributions to the strengthening and softening of composites are analysed. Thermal stresses generated at the interface between the matrix and reinforcements play a very important role. Conclusions: the incorporation of reinforcement increases both the yield stress as well as the maximum stress especially at lower temperatures. Reinforcement impact is less significant at higher temperatures. Fibres provide more effective reinforcement than particles. The flow stress (especially the yield stress) depends on the fibres plane orientation. Contributions to the flow stress originated from the higher dislocation density and the load transfer are the most important supplies. Recovery is very probably caused by cross slip of dislocations and by dislocation climb at higher temperatures. 20 figs., 2 tables, 28 sources. ALUMINIUM 7/8 (2008) Magnesiumlegierungen J. Ji, U.

Seyffarth Optimierung der Schweißparameter beim Nd:YAG-LaserstrahlMSG-Hybridschweißen von Aluminiumlegierungen Schweißen und Schneiden 60 (2008) Heft 3, S. 143-150 Für Aluminiumlegierungen ist das Nd:YAG-Laserstrahl-MSGHybridschweißen ein geeignetes Verfahren. Es bietet mehr Einflussmöglichkeiten zur Erzielung einer qualitativ hochwertigen Schweißung, erschwert aber auch wegen des angewachsenen mehrdimensionalen Parameterraums die zielgerichtete Auswahl der Parameter. Beim laserstrahlbasierten Schweißen von 100 Aluminiumlegierungen treten Nahtimperfektionen in Form von möglicher Entfestigung in der Wärmeeinflusszone, Heißrissen, Wasserstoffporen, Prozessporen und Schmelzbadauswürfen auf. Die Vermeidung dieser Nahtimperfektionen ist eine für das Erreichen einer hohen Schweißnahtqualität beim Hybridschweißen von Aluminiumlegierungen notwendige Voraussetzung. Mit den bisherigen Teilen der Veröffentlichungsreihe wurde gezeigt, dass beim Nd:YAG-Laserstrahl-MSG-Hybridschweißen von Aluminiumlegierungen die Nahteigenschaften durch die Vielzahl von verfahrensspezifischen Prozessparametern positiv beeinflusst werden können. In diesem Zusammenhang ist die Auswahl optimaler Schweißparameter eine erforderliche technologische Maßnahme zur Herstellung hybridgeschweißter Nähte mit hoher Qualität. 6 Abb., 20 Qu.

Atrens Recent Insights into the Mechanism of Magnesium Corrosion and Research Suggestions Advanced Engineering Materials 2007, 9, No. 3, S. 177-183 Magnesium is the most reactive engineering material and corrosion protection continues to be an issue of great importance. This note builds on prior reviews and our research on Mg corrosion. The corrosion performance of Mg alloys results from the high intrinsic dissolution tendency of Mg, which is only weakly inhibited by corrosion product films and the presence of impurities and second phases acting as local cathodes and thus causing local micro-galvanic acceleration of corrosion. The corrosion mechanism includes all physical features and chemical reactions when metallic Mg is exposed to an environment. Our prior work has indicated that the Mg corrosion mechanism has the following key points. In the general case, a partially protective film covers the surface of Mg and Mg dissolution occurs at breaks in this film. Hydrogen (H) evolution is associated with Mg dissolution in two separate ways. (a) An electrochemical reaction, equation 1, balances the Mg dissolution reaction, equation 2. (b) H is also produced directly by the reaction of Mg+ with water, equation 3. 6 figs., 1 table, 89 sources. ALUMINIUM 7/8 (2008) Andere Werkstoffe, Magnesium Th. Gloriant, F. Danoix, W. Lefebvre, A. L. Greer Nanocrystallized Al92Sm8 Amorphous Alloy Investigated by High-Resolution Microscopy and 3D Atom-Probe Analysis Advanced Engineering Materials 2007, 9, No. 3, S. 151-155 The discovery of Al-based metallic glasses has generated fundamental and practical interest since these amorphous alloys crystallize to a nanostructured composite containing face-centred-cubic (fcc) nanometre-sized aluminium crystallites (diameter < 20-30 nm) embedded in an amorphous matrix. They show remarkable mechanical properties, potentially useful for engineering applications. For example, the nanocomposite aluminium alloys produced by rapid solidification and subsequent annealing of Al-TM-RE alloys (TM: transition metal; RE: rare earth) show ultra-high tensile fracture strength: for the Al88Ni9Fe1Ce2 nanophase composite, the strength at room temperature is as high as 1.56 GPa far above the highest strength of conventional wrought aluminium alloys. The properties are strongly related to the volume fraction of the nanocrystallized fcc-Al particles in the amorphous matrix. We have previously presented our investigations concerning the glass-forming ability, nanocrystallization and the mechanical properties (hardness and wear resistance) of alloys prepared within the Al-Ni-Sm system. Because of the excellent mechanical properties, enhanced by a nanocrystallite dispersion, one strategy has been to control the primary crystallization (devitrification) by annealing the fully amorphous asquenched state. The nanocomposites obtained by devitrification of amorphous Al88Ni4Sm8 were found to provide very stable materials with rather good ductility in the temperature range ALUMINIUM · 7-8/2008 LITERATURE SERVICE corresponding to the primary crystallization. 4 figs., 35 sources.

Bardi Interaction between an Imidazolium Based lonic Liquid and the AZ91D Magnesium Alloy Advanced Engineering Materials 2007, 9, No. 3, S. 185-190 Mg alloys are commonly used in various industrial sectors, especially in the automotive one because of their low weight and high mechanical strength. The main drawback of these materials is the poor corrosion resistance in atmospheric and saline environments especially caused by hydrogen corrosion. One of the most resistant, and therefore among the most investigated, of these alloys is the die-cast AZ91D. For this, alloy several studies have been conducted to investigate the corrosion mechanism in saline environment. However, a complete characterization in non aqueous environments is still missing. Such of these studies could present interesting insights on the corrosion mechanism of these alloys because of the absence of water in these environments which almost totally eliminates hydrogen corrosion. In particular, ionic liquids may offer a suitable environment for this purpose. 9 figs., 1 table, 25 sources. ALUMINIUM 7/8 (2008) Magnesiumlegierungen F. M. M. Snijkers, J. v. Hoolst, M. Schoeters, J. J. Luyten Water-Based Tape Casting of Alumina and Mullite Substrates for Crystalline Silicon Solar Cell Development Advanced Engineering Materials 2007, 9, No. 3, S. 197-200 For the development of solar cells, mullite (3Al2O3 · 2SiO2) is recognised as a potential material. Mullite is widely applied for the fabrication of a variety of ceramic parts for reasons of its high refractoriness and its good mechanical properties. The choice for mullite is supported be the shortage in Si supply worldwide at present. This can possibly be overcome by deposition of Si on low-cost foreign substrates, thus saving the expensive Si material. In addition, up to date there is no substrate which is cheap enough for the use in solar cell manufacturing. A further argument for the use of mullite is found in the good match of the coefficients of thermal expansion (CTE) of silicon and the substrate material. This is a prerequisite for successful deposition of silicon at elevated temperatures. The CTE of mullite matches much better compared to that of alumina. As such, the development of solar cells that use polycrystalline silicon for the conversion of solar radiation to electrical energy, may well benefit from the advantages of mullite. 8 figs., 1 table, 15 sources.

Olschok Hydrodynamische Prozessanalyse beim Laserstrahl-MSGHybridschweißverfahren – Teil 3: Prozesssimulation und Vergleich mit Schweißversuchen Schweißen und Schneiden 60 (2008) Heft 3, S. 151-155 In diesem grundlagenorientierten Beitrag werden die Zusammenhänge zwischen Laserstrahl- und Metall-Schutzgasschweißprozess (MSC-Prozess) im Hinblick auf die entstandene Nahtgeometrie (Teil 1) und die Aufmischung von Grundwerkstoff und Zusatzwerkstoff beim Laserstrahl-MSG-Hybridschweißen (Teil 2) behandelt. Basierend auf einem Prozessmodell für das Laserstrahl-MSG-Hybridschweißen wurde ein hydrodynamisches FEM-Modell erstellt, das zur Beschreibung des Zusatzwerkstofftransports im Schmelzbad beim Laserstrahl- und Laserstrahlhybridschweißen herangezogen wurde. Die Ergebnisse der rechnerisch ermittelten Elementeverteilung wurden mit den Ergebnissen aus den Schweißversuchen abgeglichen (Teil 3). 5 Abb., 7 Qu. ALUMINIUM 7/8 (2008) Schweißen R. K. Guduru, A.

Murty Thickness and Clearance Effects in Shear Punch Testing Advanced Engineering Materials 2007, 9, No. 3, S. 157-160 The FEA results reported here show that the plastic zone formed in an SPT produces a very sharp transition to through-section plasticity at a yield point determined by a fixed (0.15%) offset on thickness-normalized SPT curves. This self-similar scaling of the plasticity produces good agreement of the shear yield stresses determined using a four-fold in-crease in either specimen thickness/clearance at fixed clearance/thickness for a range of material yield strengths. This demonstrates that the yield-point offset criterion proposed in earlier experimental work using thickness-normalized SPT curves has a rational physical basis over a wide range of thickness and clearance variation. Small changes in the yield stress that do occur with changes in either thickness or clearance can be attributed to the effects of bending in the shear zone. The choice of an offset value for experimentally based correlations between SPT and tensile tests can be based on the Von Mises yield criterion for pure shear. The offset value will depend upon the testing fixture setup/compliance and standardization of loading rates to account for rate sensitivity effects. A 1% offset was established for the testing conditions reported in. 7 figs, 9 sources.
