Distribution of Temperature Field for Rolling H-Beam

A 3D thermal-mechanical coupled was established for simulation model with technique of engineering thermodynamics and theory of nonlinear finite element during H-Beam rolling. The whole process of H-Beam rolling was repeated overall, and base on the known rolling regulations. The rules of temperature distribution were obtained for intersection deformation of web and flange during H-Beam hot rolling, and 45 steel as rolling stock. The studied achievements indicated that temperature of the stock presented tendency fall down, but tendency heighten in some domain, because of the thermal conductivity, heat radiation and convection and heat generation of plastic work done. The simulation results will have guiding meaning for defining rolling regulations and precise boundary condition of temperature for H-Beam.
