The hot rolling of large H-beam is a highly non-linear plastic deformation process,and the real-time detection of internal information for H-beam in rolled process can not be executed because of the hot environment.The finite element simulation system for large H-beam hot rolling was developed based on ABAQUS and coupled thermal elastic-plastic finite element method by customizing applications and embedding re-meshing algorithm and subroutines,which automatically achieved modeling in pre-processing and extracting simulation results in post-processing,improved the efficiency of optimizing hot rolled parameters and shorten the development cycle of developing new H-beam.The simulation system was verified through comparing the temperature field in hot rolled process of HN900×300 between simulation results and field data collected by infrared thermometer.
