Siemens to Supply Shougang Jingtang with Automation, Electrical Equipment

04/15/2011 - Shougang Jingtang United Iron & Steel has contracted Siemens to supply drive, electrical, and automation equipment for a continuous annealing line and a double-stand cold reduction mill in cold rolling mill no. 3. Commissioning is scheduled for August 2013.

Shougang Jingtang United Iron & Steel Co., Ltd. has contracted Siemens to supply drive, electrical, and automation equipment for a continuous annealing line and a double-stand cold reduction mill in cold rolling mill no. 3. The lines are designed to process tinned plate, and will be constructed in the company's plant on the Caofeidian Peninsula in the Hebei Province. Commissioning is scheduled for August 2013.
 
Siemens will supply the complete drive system, the basic automation, including the technological control systems for the continuous annealing line and the cold rolling mill, as well as the instrumentation and control system for the strip cleaning and aftertreatment in the two new lines in Shougang Jingtang. The project also includes the process automation, control desks, and human-machine interface equipment with user-friendly process and plant diagnostic functions.
 
The annealing line is designed to handle strip with thicknesses ranging from 0.15 to 0.55 mm, and reach a process speed of 760 m/min. The cold rolling mill will have a wide range of operating modes for cold reduction and skin-passing the surface of the steel strip.
 
The continuous annealing line will be automated throughout on the basis of the “Siroll PL” automation concept for strip processing lines with Simatic S7 programmable logic controllers. The control systems in the rolling stand section will be based on the Simatic TDC control system. The programming will use standardized application modules to simplify commissioning and maintenance.
 
The process automation system and the operator control and monitoring system will be equipped with standard server components, some of which will be laid out redundantly to increase availability. All main and auxiliary drives will be implemented with Sinamics AC technology.
 
The two lines will be constructed jointly with SMS Siemag AG, Düsseldorf. The continuous annealing line will feature a recrystallization furnace made by Fives Stein, Evry, France. Siemens had previously supplied equipment for two continuous annealing lines and four hot dip galvanizing lines, among others, in recent years.
 
Shougang Jingtang is a joint venture of the Chinese steelmakers Shougang Corp. and Tangshan Iron & Steel Co. It runs a production complex for processing and coating steel on the manmade Caofeidian Peninsula. The plant was relocated from the Beijing conurbation to the countryside as part of an environmental protection program, and is being continually expanded.
