Abstract

A new approach for online pass schedule calculation models for cold rolling mills is presented, which uses a full nonlinear finite element method (FEM) model exploiting the parallel computing power of graphical processing units (GPU) for the deformation process. In combination with the models for flatness, thermal crown and wear, strip temperature and an intuitive and process-oriented handling of rolling strategies the online pass schedule calculation model can improve cold rolling mill performance significantly.
