ALUMINIUM 2008
sheds its
light ahead
ALUMINIUM · 7-8/2008
Nur noch wenige Wochen, bis die
ALUMINIUM 2008 ihre Pforten öffnet – und schon jetzt zeichnet sich
ab, dass die Messe erneut ein voller
Erfolg sein wird. 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.

AKTUELLES
Bundesverdienstkreuz 1. 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.

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.

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.

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.

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.”

Konjunkturumfrage
Halbzeughandel bleibt zuversichtlich
Der Halbzeughandel in seiner
Mittlerfunktion zwischen Produzenten und Verarbeitern ist nahe
am Markt und spürt die sich
anbahnenden Veränderungen als
erster. 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

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).

mehreren Jahren rückläufig. Der Wert

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

Mit 2,52 Mio. Tonnen verzeichneten die 34 deutschen Aluminiumhalbzeugwerke 2007 eine neue

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.

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

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.

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

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

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

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.

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.

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 ©

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.

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.

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.

ALUMINIUM 2008 heading for new records
ALUMINUM 2008, which takes
place from 23 to 25 September in
Essen, will break previous records
in all fields – exhibitors, visitors,
exhibition space. More than 800
exhibitors (2006: 685) have registered so far. In view of the high
demand, the space available at the
Essen fairground will be considerably larger this year. Besides the
increase in the number of exhibitors, many of them have increased
the floor size of their stands
considerably compared with the
previous event. ALUMINUM 2008
will occupy seven halls with a
total exhibition space of 50,000
square metres.
The key players of the global aluminium industry will be exhibiting
at the world fair. More than half of
the companies are from abroad; the

41 nations, headed by Italy with 66
exhibitors, followed by Turkey (42)
and the UK (28). 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.

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. Altogether, 230 exhibitors at the fair will be present- ©

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.

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.

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

Kühlstrecke bietet mehrere Vorteile: das Sägen in der Stoppmarke
(Ausbringungsverbesserung), hohe
Auspressgeschwindigkeiten
(keine Einschränkung durch „fliegende
Säge“) und das Kühlen der gesamten
Stranglänge unter gleichmäßigen Bedingungen. „Damit sind wir prädestiniert für das Pressen dünnwandiger
und komplexer Querschnitte mit engen Toleranzen“, so Produktionsleiter
Bernd Seuren. Der neue Presswerkbereich der Alu Menziken Gruppe
gehört nun zu den modernsten und
leistungsfähigsten Anlagen dieser Art
in Europa.

ein Messwert aufgenommen werden.
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.

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

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.

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.

Almeq
ALUMINIUM 2008 – MESSEVORSCHAU
Electric preheater for cathode blocks
development, Almeq is a leading producer of crucible cleaning machines
(CCM). 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.

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

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.

forderungen entsorgt bzw. thermisch
verwertet werden, so dass kein zusätzlicher problematischer Werkstoff
in die Fertigung eingebracht wird.
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.

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.

Ruwac – Entzündlichen Aluminiumstaub zuverlässig absaugen
Aluminium- und Magnesiumstäube
sind entzündlich, wenn sie in einer
bestimmten Staub-Luft-Konzentration vorliegen. 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. Der Nassabscheider
lässt sich jederzeit auch zu anderen
Saugertypen umrüsten. Auf der Messe
in Essen wird Ruwac derartige Sauger
vorstellen und beispielhafte Lösungen
für individuell konfigurierte stationäre Absauganlagen zeigen.

Until fairly recently, plasma coating was only possible in a vacuum.
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.

SMS Meer
A broad product range for the aluminium industry
B. 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.

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.

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

as equipment supplier and if necessary
also undertakes the financing of the project.
Besides the mechanical equipment, which

in the field of process

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.

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

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

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

in
Gundelfingen
and incorporated them as

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

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-

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.

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.

• Ein weiterer wichtiger Aspekt war
die hohe Temperaturbelastung des
Kranes bei der Bedienung der Alterungsöfen. 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

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.

the crane from above. During this, the
crane also manipulates the furnace
covers (opening and closing). 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-

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

Herrmann+Hieber
… with the support of logistic specialist

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.

Fully computer-based: the control centre of a rolling mill
‘Diamond Mills‘
Ambitious rolling and cutting
technology for aluminium strips
B. 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.

The standard ‘Diamond Mill’ rolling
unit for hot- and cold-rolled aluminium strips is again the 4-high mill. As

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 ©

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.

Alu ColdMill 16Q: 6-high ‚Diamond‘ non-reversing rolling mill
the Chinalco group mainly active in
the aluminium sector already operates two ‘Fröhling’ rolling mills and
now, besides the 6-high mill, also will
receive a 4-high reversing mill.
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

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-

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.

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.

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.

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 ©

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.

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 ©

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

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.

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

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

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.

Robot-aided piercing of
vent holes in sand moulds
Vent holes in sand moulds are a
must for deaeration during casting.
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

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.

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

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

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

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

Oman signs aluminium
deal with Indian firm
A joint venture agreement involving
a government-owned investment vehicle and a major Indian metals producer promises to boost the growth
of Oman’s nascent aluminium downstream processing industry.
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.

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.

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

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

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.

load capacity – 60 tonnes maximum;
billet diameters – 152 mm, 178 mm,

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. In

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

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.

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

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

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.
The microstructure of the composite (Sample 1, Table 6) with more
than 50 wt% of AlMgB14 bonding
phase (Fig. 3) confirms that in this
case the bonding phase appears in the
form of a co-continuous network in

which several individual phases (B4C,
Al, TiB2, AlB2, Al3BC, AlB12C2 and
MgAl2O4), as well as TiB2 particulates,
are randomly dispersed.
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:

(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 ©

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.

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. Juli 2009) werde daher wieder in Shanghai stattfinden.

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

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.

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.,

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.

Optimierung der Schweißparameter beim Nd:YAG-LaserstrahlMSG-Hybridschweißen von Aluminiumlegierungen

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

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.

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

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.

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

Magnesiumknoten für Profilverbindungen
Blech, Rohre, Profile, 3/2008, S. 18-19
Das Fügen von Aluminium-Strangpressprofilen mit Magnesium-Knotenelementen bei einseitiger Zugänglichkeit der Fügestelle könnte eine Alternative zu den heute vorherrschenden
Schutzgasschweißverfahren oder den Aluminium-Druckguss-
knoten werden. In einem Forschungsvorhaben am LWF Paderborn wurden geeignete mechanische Fügeverfahren sowie
die Kombination aus mechanischen Fügeverfahren und Kleben
(Hybridfügen) untersucht. Die Ergebnisse weisen die Klebetechnik im Vergleich zum Schweißen als leistungsfähige Verbindungstechnik mit günstigen Festigkeitseigenschaften aus. Die
Entwicklung eines kombinierten Fügeverfahrens bei einseitiger
Zugänglichkeit, bestehend aus Kleben und Blindnieten, erlaubt
die sichere Fixierung der Fügeteile während der Aushärtung
und für den industriellen Einsatz die Integration in den Prozessablauf. 21 Abb.

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.

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.
