Daehan Steel of South Korea has placed an order with SMS Meer for the supply of a VCC? (Vertical Compact Coiler) rolling mill for compact coils. The mill, with an annual capacity of 450,000 tonnes, will reportedly be the world’s first rolling mill that concentrates exclusively on the production of compact coils.
The plant is scheduled to go into operation in April 2011.
SMS Meer will supply the key equipment, such as six housingless stands each in H/V arrangement for the roughing and intermediate trains, an eight-stand finishing block in V arrangement, heat treatment equipment, VCC facilities, the electrical equipment, and the automation system. It also will be responsible for the coordination of the erection and commissioning.
The production line processes billet sizes of 130 x 130 mm. Plans call for the mill to be expanded to cover billet sizes of 150 x 150 mm.
The rebar sizes correspond to the Korean standard D10 to D16; the production of corresponding round bar sizes is also said to be possible. SMS Meer says that the VCC technology is highly suitable for integration into older plants with wire rod blocks and loop laying heads to permit production of compact and stable coils.
The VCC from SMS Meer can wind bars directly in vertical position. The pass time is significantly reduced with the VCC system, the company claims, as the coils are already formed in their natural finished position.
