摘　　要：运用有限元软件建立了H型钢开坯轧制模型,对H型钢异形坯在箱形孔和异形孔中单道次轧制变形过程进行了热力耦合大变形模拟,研究了金属流动规律。The rolling model of beam blank cogging-down is established using finite element software. The deforming processes of beam blank in profiled passes are simulated with thermo-mechanical couple and large-strain method, and the metal flow pattern is also studied.
