摘　　要：通过限制热压缩试样外端区参与塑性变形的改进措施,解决了模拟连轧过程中应变速率低、总应变程度不足的问题,在实验室成功地模拟了武钢 IF 钢热轧过程。实践表明,本方法有效、正确,为今后研究 IF 钢热轧过程所涉及的各种问题创造了有利条件。In the present works,by improvement in design of compressed specimen and some effective measures to restrain plastic deformation in the gripped portion,the problems of low strain rate and insufficient strain for simulating continuous hot rolling of IF steel by Gleeble 1500 had been overcome.After comparing the MFS(Mean Flow Stress)calculated from the Gleeble 1500 testing data with the MFS calculated from industrial mill logs,it has been verified that the experimental design is correct and effective,which can be used to study hot rolling of IF steel.
