13/02/2023 – Primetals' largest automation upgrade to date implemented at Taiyuan Group

Central control station ensures “one-button steelmaking”

Primetals Technologies’ most extensive upgrade of process optimisation systems to date was recently implemented at Taiyuan Iron and Steel Group Co’s (Tisco) steel plant in Taiyuan, Shanxi Province, China. Switching to the new systems took just one week and was accomplished remotely, marking project completion two months ahead of schedule.

Primetals Technologies upgraded the Level 2 automation systems at 14 steelmaking units across the entire meltshop, seven continuous slab casters, and the central management system for raw-material logistics and evaluation. This comprehensive modernization enables Tisco to execute the steel-production process from a central control center, also sometimes called “integrated control center” (ICC). The upgrade ensures full plant automation, "one-button steelmaking", as all systems are connected to the same unified network.

The modernization of the Level 2 systems makes it possible for Tisco to calculate process parameters even more accurately using modern metallurgical models, which will improve the quality, productivity, and flexibility of Tisco’s production process.

The software system features a significantly improved user interface – the new version is easier to navigate and more intuitive for operators. In addition, the new interface simplifies the communication between the systems as well as the future implementation of extensions. The servers are virtualized, meaning that the process optimization solutions are operated without hardware, which in turn reduces the need for IT-related maintenance.

Tisco’s Taiyuan site is one of the world’s largest steel plants. Primetals Technologies has upgraded the process optimization software on 20 units in total: two electric arc furnaces, three AOD converters, one twin VOD plant, three twin ladle furnaces, two LD converters (BOF) including a ladle stirring station, two twin-RH vacuum degassing systems, and seven continuous slab casters.

Founded in 1934, Tisco is a holding subsidiary of China Baowu Iron and Steel Group. The company has long focused on the development of special steels such as ultra-wide, ultra-thick and ultra-thin strip tubes, spring steel, hand tear steel, core steel, railway steel, duplex stainless steel, and high-quality silicon steel for electric vehicles.
