【Abstract】 By Thermomechanical Coupled Finite Element Method, the hot rolling processes of H beam were simulated, and the rolling pressures and their distributions were obtained. The calculated rolling pressures are generally close to the measured data, which verifies the validity of the method. The evaluation of rolling pressures is of great importance to the design of rolling mill and the setting down of rolling schedules. The numerical simulation results showed that the maximum rolling pressures exerted on the web or outer surface of flange occur around the exiting section, and the former is greater than the latter.更多还原
