A Numerical Simulation of Hot Rolling Process of H-Beams

Abstract

To estimate the effect of roller deformation on the workpiece during the rolling process of H-beams, it is essential to consider the force exerted on the rollers and the deformation thereof. For this purpose, a three-dimension thermo-mechanical coupling model has been built with the finite element analytical package ABAQUS to simulate the hot rolling process of H-beams. In particular, the simulation is conducted under the assumption that the rollers are elastic and rolling torque imposed unilaterally, which agrees with the practical rolling conditions. Noting the results of FEM simulation, the metal flow and temperature distribution have been obtained. To verify the effectiveness of the proposed simulation, comparisons of the roller contact reaction and temperature between the simulated and measured values have been made. The simulation is meaningful for preparing continuous rolling procedures of H-beams.
