New Profile and Flatness Calculator Optimises Hot Rolling at ArcelorMittal

Mathweis Engineering GmbH, allpccloud GmbH, and pa-innovations GmbH have long collaborated on the development of advanced rolling models and Level 2 automation systems.

As part of the ongoing modernisation of ArcelorMittal Eisenhüttenstadt’s hot strip mill, the Profile and Flatness Calculator (PFC) has been upgraded, integrated into the existing automation infrastructure, and successfully commissioned. The enhanced PFC employs FEM-based, real-time process models to simulate stand deformation and plastic-elastic strip behaviour within the roll gap. This significantly improves theprecision of profile and flatness control, particularly in managing cross-flow effects during hot rolling.
