CVS covers the complete design and manufacturing activities for green‐field green field projects as well as revamping/upgrading of existing plants and equipments. CVS manufactures spare parts & components for Meltshops & Rolling Mills & Off Off‐Gas Gas Systems. Systems CVS provides technical assistance and consulting service to steel production. C O M PA N Y O V E R V I E W CVS headquarter q is located in the most sophisticated p industrial region of Turkey; Gebze (50 km to Istanbul city center), close to many major ports. Our modern facilities consist of three integrated major‐sized workshops equipped with post‐modern machinery parks and three engineering buildings summing up approx. 100,000 sqm. CVS workforce is formed by over than 750 specialized staff with a modern machinery park to undertake d t k even the th mostt challenging h ll i projects. j t More than 270 engineers and administrative employees are involved in the design and management of the projects. ACTIVITIES CCM ‐ GENERAL PLAN VIEW CCM ‐ SIDE VIEW CCM ‐ DESIGN CONCEPT According to customer request, CCM can be equipped with the necessary modern equipment to produce high quality casted products, such as tundish of delta type to reduce inclusions in the mould, long copper tube to improve primary cooling on the billet surface, automatic mould level control system, high casting radius to reduce stress during unbending, secondary spray cooling divided in three zone for a better cooling effect and control, walking beam cooling bed for the straightening of the long billets. CCM ‐ SAMPLE PROJECT CCM ‐ DESIGN CONCEPT CCM can be designed to produce square billets in the sections between 100 to 200 mm² and blooms between 180 to 260 mm². Special designs for beam blank and round sections between 160 to 440 mm can be done. Radius of 5‐12 m and mould length of 750‐1000 mm can be designed according to project requirement. requirement For some special casting, casting vertical continuous casting application can be considered. considered The CCM can be fitted with up to eight casting strands in order to satisfy the production schedule given by the EAF.
