On June 26th, a milestone breakthrough was achieved in China's metallurgical engineering technology sector—the 1550mm pickling and tandem cold rolling mill of Guangxi Hongwang New Material Technology Co., Ltd., constructed by MCC Jingcheng Engineering & Technology Corporation, successfully completed its one-time hot commissioning and smoothly produced the first coil of electrical steel, marking a historic leap forward in China's high-end electrical steel production equipment sector. As the first domestically developed wide-strip high-speed electrical steel continuous pickling and tandem cold rolling mill in China, the success of this project not only filled a gap in the industry but also highlighted MCC Jingcheng Engineering & Technology Corporation's leading role in advancing the localisation of metallurgical equipment.
