摘　　要：借助有限元分析软件MSC.Marc,对大规格H型钢开坯轧制过程进行有限元模拟,分析轧件的变形特点。结果表明:大规格H型钢开坯轧制时轧件各部位变形不均匀,翼缘与腹板的变形不一致;腹板部位"舌头"的产生是由于轧件各部位延伸不均匀所致,腹板部位较薄导致轧制过程易出现倾斜失稳现象。开发适合大规格H型钢轧制的孔型系统具有重要意义。With the aid of finite element analysis software MSC.Marc,the process of break-down rolling of large H-beam with profiled billet was simulated,and the deformation characteristics of workpiece were analyzed.The results show that deformation of different parts of workpiece is inhomogeneous during rolling,the deformation of flange and web is inconsistent.The"tongue"in the site of the web is caused by the uneven extension of various parts of the workpiece;and the thinner web site leads to the slope instability in the rolling process.It is significant to develop a proper pass system for large H-beam rolling.
