Thermal Mechanical Coupled 3D Finite Element Simulation of Large H-Beam in Hot Rolling Process

Abstract:

In order to research the forming process of H-beam, based on the large H-beam production line of HN600x200, the Standard and Explicit solver of ABAQUS are synthetically used to establish finite element model for rolling process and inter-pass thermolysis process. The reciprocation multi-pass rolling process simulation procedure based on the re-meshing technology is used to simulate the whole production process form blanks to finish products, and the continuity of data is ensured. Based on the simulation results, the deformation and rolling force of the roller as well as the metal flowing law and temperature field of workpiece are discussed emphatically. The results clearly show that the displacement of roller contains the elastic deformation and the deflection, and the counterforce of left adds to the counterforce of right is about equal to the resultant force. The simulation results are compared with the measuring results, which proves the correctness of simulation.
