Shougang Rolls First Coil on SMS Demag Pickle Line Tandem Cold Mill

01/02/2008 - China Shougang produces its first coil on the new pickling line/tandem cold mill that was supplied and commissioned by SMS Demag.

China Shougang Corp., Beijing, China, recently produced the first coil on its new pickling line/tandem cold mill (PL/TCM). The facility had been supplied and commissioned by SMS Demag AG.
 
SMS Demag’s supply scope included the tension leveler, ASC side trimmer with scrap chopper, turbulence-tank pickling process model, and the five-stand tandem cold mill in CVC plus®, six-high technology with ESS mode and AIO design, as well as a carrousel reel and all necessary ancillary equipment. The cold mill includes provision for the future installation of an edge-drop compensation system (EDC). SMS Demag also supplied a modern strip inspection line, tailor-made for the particular requirements of continuous quality assurance for automotive sheets.
 
Before pickling, the width of the strips produced on the PL/TCM is between 800 and 1900 mm, and the strip gage is between 1.6 and 6.0 mm. The annual production will be around 1.8 million t with strip widths up to 1870 mm and final strip gages between 0.2 and 2.5 mm. The maximum pickling rate is 230 meters/minute and the maximum rolling speed is 1400 meters/minute.
 
The new PL/TCM enables Shougang to produce the very latest steel grades, such as deep-drawing qualities for the automotive industry and multiphase steels, thus safeguarding its market position.
