An analytical model for the prediction of the transfer bar temperature in a roughing mill

Abstract

An online model is presented for the prediction of temperature distributions in the bar in the roughing mill of a hot strip mill. The model consists of an analytic model for the prediction of temperature distributions in the interstand zone, and a semianalytic model for the prediction of temperature distributions in the bite zone. The prediction accuracy of the model is examined through comparison with predictions from a finite element model.
