The new hot mill is an essential part of the strategic expansion project of Henan Yirui, a subsidiary of the Henan Mingtai group, which is located in the city of Gongyi, Henan Province, P.R. China. Henan Yirui’s trust in the experience of SMS group and its outstanding number of successful references in the aluminum industry has fully paid off.
SMS group developed a solution to refurbish and integrate components of a second hand 1+1 Hot Mill into the new 1+4 Hot Strip Mill at the Gongyi site. We supplied the mechanical equipment, fluid systems, X-Pact® electrical equipment and process automation. Three brand-new finishing mill stands feature the leading CVC® technology for superior strip quality. The new mill exit includes a side-trimming shear of novel design, a down coiler unit and an offline strip surface inspection station. The new hot strip mill can produce trimmed strips up to 2,150 mm widths.
Rolling of the first coil was originally scheduled during the first quarter of 2024. But installation and commissioning was significantly shortened due to the superior engineering and the outstanding efforts, dedication and commitment of Henan Yirui and SMS group. This achievement is particularly noteworthy given the challenging conditions during the pandemic.
A particular challenge was the seamless integration of second hand equipment into a most modern 4-stand tandem mill. We at Henan Yirui were convinced by SMS' solution and ultimately impressed by its smooth implementation. The new SMS X-Pact® Level 2 process model controls the re-used roughing mill and the new finishing tandem mill, thereby creating a fully integrated 1+4 aluminum hot strip mill.
The Chinese aluminum manufacturer has thus continued its successful cooperation with SMS group which started with orders for a 6-hi Cold Rolling Mill and an AMOVA high-bay coil storage system.
