Rolling models adaptive setup modes for cold rolling mills

A portfolio of models from ABB can help customers to optimize their mills to improve productivity. These model has the work-hardening curve of the material, a roll-gap friction model, the roll-gap model, and the mill model for providing the references for the strip-flatness actuators and the roll-gap positions. Measured values are collected, filtered during each pass, and then compared with the corresponding predicted values. The rolling model has a package of different sub-models that are closely connected to each other and based on physical principles. Setup- and adaption-reports can be produced for every coil and stored to the database for analysis and offline tuning of the model. The pass schedule can identify a suitable distribution of the reductions over different passes for given coil data. ABB's Preset model solutions for cold rolling mills can help to improve product quality and productivity.
