CERI's Self-developed Silicon Steel Pickling Line and Tandem Cold Mill was Put into Operation

Date：2025-08-05
Recently, China's metallurgical engineering technology field has ushered in a milestone breakthrough - the hot commissioning of the 1,550 mm pickling line and tandem cold mill of Guangxi Hongwang New Materials Technology Co., Ltd. built by MCC Capital Engineering & Research Incorporation Limited (hereinafter referred to as "CERI") was successfully at one time, and the first coil of silicon steel was successfully produced, marking that China has achieved a historic leap in the field of high-end silicon steel production equipment. As the first fully independently developed wide-width high-speed silicon steel pickling tandem rolling line in China, the successful project not only fills a gap in the industry, but also demonstrates CERI's leading role in promoting the localization of metallurgical equipment.

 

Breaking the Technology Monopoly and Setting a Benchmark for Localization 

 

For a long time, the core technology of high-end silicon steel production has been monopolized by foreign companies, becoming a bottleneck restricting the development of China's silicon steel industry. Faced with the growing domestic silicon steel market demand and continuously upgraded energy efficiency standards, CERI established a special technical research team based on decades of technical accumulation in the field of metallurgical engineering. Through continuous innovation and breakthroughs, it independently developed and launched the first completely domestically produced 1,550 mm high-speed silicon steel pickling line and tandem cold mill. The 1550 mm unit put into production this time innovatively incorporates the work roll shifting technology, adopts the composite application of work roll and intermediate roll shifting, and realizes the stable production of thin-gauge wide-width silicon steel. The product plate shape accuracy and transverse thickness difference have reached the international leading level, and the maximum rolling speed of the unit has reached 1,500 m/min. The overall technical indicators exceed similar imported equipment, providing strong equipment support for improving the competitiveness of China's silicon steel products. 

 

 

 

Innovation Drives Development and Leads Industry Upgrading 

 

CERI has given full play to the innovation advantages of a national enterprise technology center and overcome a series of industry technical barriers in the process of unit design and R&D. By deeply integrating intelligent technology with traditional processes, precise control and efficient operation of the production process are achieved. The unit adopts advanced green and environmental protection design concepts, performs outstandingly in energy conservation and emission reduction, and fully reflects the development direction of intelligent and green modern metallurgical equipment.
