Shanxi Taigang Stainless Steel revamps plant No. 1

After the successful commissioning of the new 80-ton Duplex RH-TOP plant No. 2 (Ruhrstahl Heraeus process) in last April, Taigang Group International Trade Co., and the plant operator Shanxi Taigang Stainless Steel Co., (TISCO), both located in Taiyuan, China, have successfully revamped and commissioned the existing 80-ton Duplex RH-TOP plant No. 1. SMS Mevac, Germany, supplied the new RH plant and revamped the existing one in cooperation with its consortium partner SMS Siemag Technology (Beijing) Co.
Shanxi Taigang Stainless Steel can now use both 80-ton RH-TOP plants for the refining of various high quality steel grades with low levels of hydrogen. The plants will primarily be used for the treatment of steel for electric sheet production. Both plants generate vacuum by a four-stage steam-ejector vacuum pump with variable pressure reduction (RH-SC) for optimised process control.

SMS Mevac’s scope of supply for this project included nearly the complete basic engineering, the main part of the detail engineering, the delivery of key components for the mechanical, electrical and instrumentation equipment, the complete level 1 and level-2 automation systems as well as supervision of installation and commissioning.
