Hyundai Steel has successfully put a 4.3m heavy-plate mill on stream. The 4.3m mill supplied by SMS Siemag is designed for an annual production of 1.5 million tons of heavy plate in thicknesses from 6mm to 200mm. The main sales markets for the plates are to be the shipbuilding and the construction industries. Together with the 5m heavy-plate mill, which has been producing since 2009, Hyundai Steel now runs two heavy-plate mills from SMS Siemag, Germany, at the Dangjin location in South Korea.
SMS Siemag supplied the mechanical equipment and the X-Pact electrical and automation system. The main facilities of the heavy-plate mill are the descaler, the finishing stand with edger, the plate cooling system with pre-leveller, the hot-plate leveller, two cooling beds, the four-shear shearing line and the cold-plate leveller.
Special plant engineering highlights are the mill stand with the hydraulic adjustment system, the work-roll bending and the CVC plus systems, as well as the plate cooling system that provides very high cooling rates and varied cooling patterns for a wide range of sophisticated steel grades.
The 4.3m heavy-plate mill of Hyundai Steel operates with SMS Siemag’s X-Pact level-1 and level-2 automation system. This system had been subjected to an integration test (Plug & Work) and pre-optimised before commissioning.
