Abstract:Thermal mechanically coupled 3D finite element simulation for multi-pass reversing breakdown rolling of H-beam was conducted.The construction of FEM model,material parameters,boundary conditions and loading in the simulation were introduced in details.The couple-field result(structure and thermal field) was obtained.Thermal fields were deeply analyzed.The simulation results coincide well with the measured values.This paper provides references for the thermal mechanically coupled-field simulation of the multi-pass rolling process by FEM.
Keywords:H- beam    thermal-- mechanical coupling    FEM   reversing breakdown rolling
