Shanxi Taigang Stainless Steel Co . Ltd . ( Tisco ), located in Taiyuan , China , has successfully produced the first plate on its new 4.3-meter heavy plate mill supplied by SMS group . It is the most powerful hot rolling mill of its kind ever supplied by SMS . The rolling force of 109 MN in relation to the roll barrel length of 4.3 meters provides the mill a very innovative design and high environmental compatibility . A further distinguishing feature of the mill is the wide range of material it can roll , including carbon steels , quality steels , low-alloyed steels , grades for ship , bridge and pressure vessel construction , weather- and wearresistant plates , pipe grades according to the API standard , as well as stainless steel and nickel-based materials . The 4-high rolling stand with attached edger is the central production unit of the heavy plate mill . The vertical edger features combined mechanical / hydraulic roll gap adjustment to achieve extremely tight tolerances . To be able to process even very short slabs , the heavy edging stand is equipped with a newly developed , specially driven support roller table . The rolling stand is characterised by high rolling forces and a correspondingly high forming capacity . The combination of a very large roll gap opening and the coaxial CVC ® plus ( Continuously Variable Crown ) technology with integrated powerful work roll bending is a new development that allows rolling stock with initial thicknesses of up to 960 millimeters to be processed .
Features SMS achieved the extremely high stiffness factor of the mill by means of various technological design features , such as the use of 2.3-meter backup rolls . Another characteristic feature is the mill ’ s maintenance-friendly design . With their decades-long experience in heavy plate rolling technology , SMS was able to consider comprehensive operating experience and feedback received from customers in the design of the new mill .
