Taigang Group International Trade Co., Ltd., and the end user Shanxi Taigang Stainless Steel Co., Ltd., both located in Taiyuan, China, have successfully put on stream its new 80-t Duplex RH-TOP plant (Ruhrstahl Heraeus process) supplied by SMS Mevac, Germany (www.sms-mevac.com), and its consortium partner SMS Siemag Technology (Beijing) Co., Ltd.
This 80-t RH-TOP plant No. 2 enables the refining of various high-quality steel grades with low levels of hydrogen. Primarily, the plant is being used for the treatment of steel for electric sheet production.
The vacuum is generated by a four-stage steam-ejector vacuum pump with splash control system (RH-SC®) for reducing the splashing of steel.
Within this project, SMS Mevac’s supplies included nearly the com-plete basic engineering, main parts of the detail engineering, the delivery of key components of mechanical, electrical and instrumentation equipment, the complete level-1 and level-2 automation systems as well as supervision of installation and commissioning.
SMS Siemag AG and SMS Meer GmbH are both companies of SMS group which, under the roof of SMS Holding GmbH, consists of a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry.
