Siemens to Supply Plate Mill for Dongkuk

10/08/2007 - Siemens Metals Technologies will supply the entire mechanical equipment and automation system for a new 5-meter wide plate mill for Dongkuk Steel Mill.

Siemens Metals Technologies has received an order from Dongkuk Steel Mill Co. Ltd. to supply the entire mechanical equipment and automation system for a new 5-meter wide plate mill.
 
For the project Siemens will operate as part of a consortium led by Sojitz Corp., Japan. The consortium also includes Hyundai Heavy Industries, Korea.
 
The new plate mill, which will roll plates up to 4.9 meters wide, will be built at the company’s Dangjin works. Its scheduled production capacity will be 1.5 million tonnes per annum, increasing Dongkuk’s total production capacity of plates for shipbuilding, pipe making and construction to 4 million tonnes per annum. At the new plant, it will be possible to roll plate with thicknesses of between 4.5 and 150 millimeters.
 
The mill comprises a 4-high stand equipped with long stroke hydraulic automatic gauge control capable of producing 11,000 tonnes of rolling force, plus work-roll shifting functions based on SmartCrown technology and heavy bending, and a Mulpic intensive plate cooling section. Siemens will also equip the mill with a hot leveler, three cooling beds, and a shearing line consisting of a crop shear, double side trim shear, slitting shear, and divide shear.
 
In addition to the mechanical equipment, Siemens will also supply the entire automation system, including sensors. The automation system comprises the basic automation, including all the technological control systems, as well as operation and visualization equipment and the process automation functions. Due to the close interaction of analytical process models and technological closed-loop control systems, all the process parameters are kept within close tolerance limits.
 
Functions such as plan view pattern control and thermo-mechanical rolling are also part of the Siemens solution. A rolling-sequence control system enables nested multi-plate rolling. This will enhance the productivity of the plant. This flexible system can be adapted to changes in the range of products or the quality requirements, thus safeguarding the original investment. A higher-level material-tracking system ensures the smooth flow of material and correct correlation of plates and process data at all times. All the components and systems used are part of “Siroll PM”, Siemens’ integrated solution for plate mills. In addition, Siemens is responsible for commissioning and customer training.
 
Production of the first plate is scheduled for the end of 2009.
 
Dongkuk Steel Mill Co. Ltd. is a leading steel producer in Korea. Dongkuk and Siemens have previously completed a series of projects together, with Siemens supplying, modernizing, and expanding capacity of Dongkuk’s existing plate production facilities.
