FE-based On-Line Model for the Prediction of Strip Temperature in Hot Strip Rolling

Abstract

Investigated via a series of finite‐element(FE) process simulation is the effect of diverse process variables on some selected non‐dimensional parameters characterizing the thermomechanical behavior of the roll and strip in hot strip rolling. Then, on the basis of these parameters, on‐line models are derived for the precise prediction of the temperature changes occurring in the bite zones as well as in the inter‐stand zones in a finishing mill. The prediction accuracy of the proposed models is examined through comparison with predictions from a FE process model.
