At 9:58 a.m. on January 9, 2023, the 900mm special strip mill of Shanxi Jingang Group, whose mechanical, electrical and hydraulic equipment and factory were contracted by ZZ, succeeded in the one-time hot load test run. The first coil is perfectly produced under the whole process of roughing, finish rolling, coiling, packaging and marking, and the coil shape is neat and the process is smooth. ZZ’s excellent technology and excellent equipment performance received recognition from the customer.
This special strip mill is one of the key projects of Shanxi Jingang Group to further improve the functions of the upstream and downstream industrial chains of steel manufacturing, carry out deep processing and realize the vertical integration of the steel industrial chain. It will mainly produce alloy steel, tool steel, spring steel and high-strength structural steel to be widely used in automobiles, molds, chains, pressure vessels, saw blades and other fields.
This production line applies advanced full continuous rolling technology. All the horizontal mills have hydraulic AGC control and edgers have AWC control and SSC control. The automation system includes L1 basic automation and L2 process automation. Hydraulic loopers are set between finishing mills, and online controlled cooling process is provided after rolling. The mill is also equipped with intelligent equipment such as thickness gauge, width gauge, packaging and marking manipulators.
High-precision equipment, high degree of automation and intelligent control system provide a strong guarantee for high-quality and high-precision products. The full continuous rolling process also has the advantages of high product precision, low energy consumption, short process, fast pace, small temperature difference between head and tail, good profile, high yield and less scale loss.
ZZ has rich experience in designing and manufacturing complete sets of strip mill equipment in the fields of special strip, stainless steel and plain carbon steel. The 900mm special strip mill of Shanxi Jingang Group is ZZ’s another masterpiece in the field of special strip.
Thanks to the leaders at all levels of Shanxi Jingang Group and the 900mm special strip mill project team for their trust and support, to the construction unit Hebei Metallurgical Construction Group for their sincere cooperation and strong support, and to Binhai Design Institute, Northeastern University, Shanghai Electric Machinery Co., Ltd, Ningbo DONLY Co., Ltd., Chongqing Pump Industry Co. Ltd., Taier Group, Hangzhou Zheda Jingyi Electromechanical Technology Co., LTD. and other partners for their sincere cooperation.
