摘　　要：应用热力耦合大变形有限元方法 ,模拟了 H型钢的热轧变形过程 ,给出了轧制力的大小及其分布方式。数值模拟结果表明 :H型钢腹板与翼缘外表面单位轧制力的最大值一般均出现在出口截面附近 ,且前者比后者大得多。此外 ,模拟计算值与实测值比较接近 。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.
