Finite Element Simulation of Large H-Beam in X-H Rolling Process
Abstract:
In order to research the hot rolling process of large H-beam, the thermal-mechanical coupling analysis and big distortion theory are used to simulate the whole X-H rolling process of HN900x300 by ABAQUS, in which the re-meshing technique is taken into simulation to increase the accuracy. Based on the simulation results, the stress and deflection of the roller as well as the metal flowing law and temperature field of workpiece are discussed emphatically. The results clearly show that the roller is subjected to alternating shear force and compressive stresses of three directions, and the metal of flange tends to flow from outside to inside. The simulation results are compared with the measuring results, which proves the correctness of simulation.
