摘　　要：热轧H型钢精轧设备采用连续式布置方式,整个过程中轧件塑性变形量较大,直接采用商用软件进行有限元分析,存在运算量过大、运算时间过长的缺点,并且运算过程会因单元畸变而中止。故此,采用网格重构的方法对连轧过程进行了分段式有限元模拟,通过对H250×125×6×9规格H型钢精轧过程的分析及结果验证,证实了该分析方法的可行性及有效性,为处理类似的金属塑性成形仿真问题提供了有益启示。During the process of the hot finish-rolling of H-beam, the metal＇s deformation is excessive and complex in the continuous lay of rolling mills. Simulation with adoption of FEM software costs massive calculation and long CPU time, and could break by the excessive deformation of the mesh elements. To overcome these shortcomings, a brick element re-meshing technique is presented for hot finish-rolling process simulation, the finish-rolling of typical type H250 × 125 × 6 × 9 is analyzed by the proposed numerical analyses technique. The results show that the method is feasible and effective for shaped metal forming process simulation.
