SMS Demag to Supply Heavy-Plate Rolling Mill for Hyundai Steel

12/17/2007 - SMS Demag will supply a new heavy-plate rolling mill—including complete mechanical and automation systems for the entire process line—for Hyundai Steel at Dangjin, South Korea.

Hyundai Steel Corp., South Korea, has placed an order with SMS Demag to supply a 5-meter heavy-plate rolling mill. The new facility is being built in Dangjin on the east coast of South Korea.
 
SMS Demag’s supply scope comprises the mechanical and automation systems for the entire process line, including finishing stand, hot plate leveler, cooling beds, shearing line and finishing line with cold plate leveler.
 
With its new works, Hyundai Steel intends to concentrate on the manufacture of ship plates, though it will also be supplying plates to the construction and mechanical engineering industries as well as pipe grades. The new facility will be designed for the production of plates ranging in width from 900 to 4800 mm and in thickness from 6 to 200 mm. With an annual production of approximately 1.5 million tonnes of finished plate, the new facility will also be capable of expansion to 2 million tonnes in the future with the installation of a roughing stand.
 
With a rolling force of 100 mN, the mill stand is equipped with CVC plus® technology to enable close profile and flatness tolerances to be achieved. Designed as a laminar cooling system, the plate cooling system can be expanded in the future to include a pre-leveler and spray cooling. The shearing line’s four shears operate according to the rolling-cut principle, and the dividing and cropping shears feature a closed-type design that will help to optimize cut-to-length accuracy and edge quality, particularly for high-strength plates. The mill is equipped with a hot plate leveler as well as a cold plate leveler in 9/5 design with an extended leveling range that will help to optimize plate flatness.
 
SMS Demag will set up and test the entire automation system in its test facilities according to the Plug & Work concept. Plug & Work simulates the production sequence and allows automation functions to be tested and optimized under realistic conditions prior to installation in the works.
 
The new facility will go into operation in late 2009.
