Primetals Technologies has secured a contract from Shougang Cold Rolling Co, Ltd to modernize the automation systems of its Pickling Line Tandem Cold Mill (PLTCM) facility in Shunyi, Beijing. The project includes the upgrade of both Level 1 basic automation and Level 2 process automation systems, along with the refurbishment of a key drive unit within the production line. Completion is scheduled for August 2026.
The modernization initiative is designed to strengthen operational reliability, improve process control, and establish a future-ready automation platform capable of supporting evolving production requirements. By replacing legacy systems with advanced digital technologies, the facility will benefit from enhanced efficiency, simplified maintenance, and reduced operating costs.
A key component of the project is the implementation of a new-generation Level 2 process automation platform. The upgraded system will introduce sophisticated process models, enhanced data management capabilities, and improved production analytics. These enhancements will provide greater control accuracy throughout the manufacturing process, helping operators achieve more stable production conditions and higher consistency in finished products.
The investment supports Shougang Shunyi’s strategic focus on premium cold-rolled steel products used in demanding applications such as automotive manufacturing and household appliances. Improved process stability and tighter quality control are expected to further strengthen the company’s position in high-value steel markets where precision and product performance are critical.
To ensure a smooth transition, Primetals Technologies will deploy its proprietary Chart Converter software, a specialized migration solution developed to minimize production interruptions during automation upgrades. The application automatically converts existing software to the latest TIA S7-1500 platform while preserving full functional equivalence. This approach significantly reduces commissioning time and enables a faster return to normal production operations.
The project reflects the growing trend among steel producers to modernize existing assets through digital transformation rather than undertaking large-scale equipment replacement. By extending the life cycle of critical production infrastructure, manufacturers can improve competitiveness while maximizing returns on previous investments.
Located in Shunyi, Beijing, Shougang Cold Rolling is a subsidiary of the Shougang Group, one of China’s largest steel producers. The company specializes in the production of advanced cold-rolled steel products that serve automotive, appliance, and industrial sectors across domestic and international markets.
Primetals Technologies continues to expand its presence in advanced steel manufacturing technologies, digital automation systems, and intelligent process optimisation solutions for steel producers worldwide. The company said the latest modernization project reinforces its focus on helping steel manufacturers improve efficiency, product quality, and operational sustainability through advanced engineering and automation technologies.
