Henan Yirui New Materials Technology Co., Ltd., a subsidiary of the Henan Mingtai group, signed a final acceptance certificate for its new four-stand aluminum hot finishing mill installed and commissioned at its site in Gongyi, Henan Province, China.
As part of the installation of the new mill, an existing single-stand hot rolling mill (consisting of a reversing roughing mill and a single-stand reversing finishing mill in a 1+4 tandem configuration) was successfully converted into the new tandem hot finishing finishing mill by adding three new finishing mill stands — bringing it to a total of four stands. The new hot strip mill can produce trimmed strip up to 2,150 mm wide.
SMS supplied the mechanical equipment, fluid systems, and the X-Pact® electrical equipment and process automation for the project. All three new finishing mill stands feature cutting-edge CVC® technology for superior strip quality. The mill exit area includes an innovative side-trimming shear, a down coiler unit, and an offline strip surface inspection station.
“Installation and commissioning times were significantly shortened thanks to the superior technology and the outstanding efforts, dedication, and commitment of Henan Yirui and SMS group,” said Liu Jie, general manager of Henan Mingtai Aluminium. “The seamless integration of the secondhand equipment into the process automation of a highly advanced four-stand tandem mill was a challenge. SMS group’s solution to incorporate the roughing mill smoothly into the X-Pact Pass Schedule Calculation (PSC®) system supplied for the new finishing tandem mill was impressive.”
Thanks to the solutions developed by SMS group, the mill started production two months earlier than originally planned.
“Throughout the project it has always been a real pleasure to work with such highly motivated and dedicated project teams from both parties,” said Rüdiger Roger Wiechmann, project manager at SMS group. “The flat decision-making hierarchy on the customer side was also very helpful.”
