Numerical Modelling and Simulation of the Hot Rolling Mill Process

Abstract:

In the design of the rolling mill plants, it is fundamental to study the behaviour of the deformation process to assess the main process variables (such as torque and rolling force) in all operating conditions.In this paper, a finite element model is developed and the numerical simulations of the plastic deformation process, in the hot rolling mill of AISI 304 stainless steel, are shown. In the proposed model a Multilinear Isotropic Hardening behaviour of material has been assumed and true stress-true strain curves have been found, taking into account temperature and strain rate. Numerical results are compared with experimental measures regarding an existing hot rolling mill plant.
