Finite Element Analysis of 3D Transient Thermo-mechanical Behav-ior of Work Roll in Hot Strip Rolling

An integrated finite element-based model is presented for the prediction of the three dimensional tran-sient thermo-mechanical behavior of the work roll in hot strip rolling. The model is comprised of basic finite element models which are incorporated into an iterative solution procedure to deal with the inter-dependence between the thermo-mechanical behavior of the strip and that of the work roll which arises from roll-strip contact as well as with the interdependence between the thermal and mechanical behav-ior Demonstrated is the capability of the model to reveal the detailed aspects of the thermo-mechanical behavior and to reflect the effect of various process parameters.
