ArcelorMittal to upgrade Hot-Strip Mill

Primetals is supplying level 1 and 2 automation systems, some of the auxiliary drives and sensors for the hot strip mill in Sestao, Spain. The modernization is expected to lead to higher yields and better product quality.

According to Primetals, state-of-the-art control systems will ensure an increased yield by reducing downtime and enhancing mill availability. Additionally, the process optimization system enables more accurate calculations for the production process, minimizing production disruptions and further optimizing yield. Recently, Primetals Technologies implemented a similar Level 1 automation system at ArcelorMittal’s hot-strip mill in Eisenhüttenstadt, Germany.
The Level 2 automation system is based on advanced mathematical models related to thermodynamics and other branches of physics. A comprehensive model calculates temperatures holistically throughout the entire rolling mill and cooling area, resulting in improved winding temperatures and a refined microstructure. Primetals’ process models utilize modern optimization methods and sophisticated AI-backed machine-learning algorithms to enhance product quality.
