05/29/2007 - Dongkuk Steel Mill, South Korea, has awarded a contract to SMS Demag to modernize the mill train of it No. 2 Heavy Plate Mill, including the installation of CVC plus technology on the existing mill stand and more-powerful hydraulic roll-gap adjusting systems in the finishing stand.

Dongkuk Steel Mill Co. Ltd., South Korea, has awarded a contract to SMS Demag, Germany, to modernize the mill train of it No. 2 Heavy Plate Mill.
 
As part of the revamp, SMS Demag will for the first time equip an existing heavy-plate mill stand with the CVC plus® technology. SMS Demag’s scope of supply also includes installation of more-powerful hydraulic roll-gap adjusting systems in the finishing stand, a new Level-2 automation system, and technological control systems (TCS) including pass-schedule calculation for the entire mill line.
 
Installation of CVC plus technology in the finishing stand will help Dongkuk Steel to enhance product quality and increase production capacity, while the new, more powerful hydraulic (roll-gap) adjusting systems will help the mill achieve a rolling force increase from 80 to 90 N. The combination of technologies will facilitate allows greater pass reductions as well as flexible production due to the free organization of a rolling campaign.
 
For work roll shifting, SMS Demag will fit new spade end spindles with integrated length compensation.
 
The new equipment units are scheduled to go into operation in early 2009. Prior to startup, the automation system will be tested extensively in large-scale integration tests to ensure short commissioning and quick achievement of target production levels.
 
This project follows SMS Demag’s supply of the descaler, hot plate leveler, two cooling beds, and five shears for Dongkuk Steel’s original two-stand heavy plate mill, which was started up in 1997.
