FE-based on-line model for the prediction of roll force and roll power in hot strip rolling

Abstract

Investigated via a series of finite element process simulation is the effect of diverse process variables on some selected non-dimensional parameters characterizing the thermo-mechanical behavior of the strip in hot strip rolling. Then, on the basis of these parameters an on-line model is derived for the precise prediction of roll force and roil power, The prediction accuracy of the proposed model is examined through comparison with predictions from a finite element process model.
