摘　　要：采用热力耦合弹塑性三维有限元方法,对莱钢H型钢生产线HN800 mm×300 mm规格产品的轧制全过程进行仿真。并采用网格重构的方法,重点分析了型钢轧制过程TM机组可逆连轧中轧件的变形行为和温度场分布。研究结果表明:轧件变形主要是翼缘变形,随着翼缘厚度的减小,还会出现金属内翻现象;同时,腹板和翼缘表面温差很大,在空冷200 s后,温差可达160℃左右。因此,分析掌握轧件的变形规律及温度变化情况,可以为生产实践提供理论依据。The whole rolling process of HN800mm×300mm H-beam produced by LaiGang was simulated by 3D thermal couple numerical simulation.The deformation behavior and the temperature distribution during TM reversible rolling process were analyzed by the excessive deformation of the mesh elements.The results indicate that the main rolling deformation is the flange.With the flange thinning,metal varus will occurs.At the same time,surface temperature difference is between the web and the flange,which can be up to 160℃ more or less after 200s cooling.The research can grasp the rolling deformation and temperature changes,provide the theoretical basis for productive practice.
