摘要：

轧制力的预测是热轧工艺能够顺利进行的重要前提步骤。为预测热轧过程中轧制力的大小，采用热模拟试验机对07MnNiMoDR钢进行了单道次热压缩实验，获得了温度为850~1150 ℃、应变速率为0.1~10 s-1、真应变为0.9条件下的高温流变行为，分析了不同变形条件下07MnNiMoDR钢的动态再结晶及动态回复行为，并基于Arrhenius方程及变形机理建立了其热轧本构方程。利用材料性能分析软件JMatPro计算了07MnNiMoDR钢的温度场参数；基于高温热轧本构方程及温度场参数，通过有限元分析软件Deform-3D对热轧过程进行模拟，验证了轧制力预测的准确度。结果表明: 所建立的07MnNiMoDR钢的本构方程及温度参数，对预测轧制力具有良好的预测精度，R值为0.9875。

The prediction of rolling force is an important prerequisite for the smooth running of hot rolling process. Therefore, in order to predict the rolling force in the hot rolling process, the single-pass hot compression test of 07MnNiMoDR steel was conducted by thermal simulation test machine to obtain the high temperature rheological behavior under the conditions of the deformation temperature of 850-1150 ℃, the strain rate of 0.1-10 s-1 and the true strain of 0.9. Then, the dynamic recrystallization and dynamic recovery behavior of materials under different deformation conditions were analyzed, and based on Arrhenius equation and deformation mechanism, the hot rolling constitutive equation of experimental steel was established. Furthermore, the temperature field parameters of 07MnNiMoDR steel were calculated by the material property analysis software JMatPro, and based on the high temperature rolling constitutive equation and temperature parameters, the prediction accuracy of rolling force was verified by software Deform-3D, The results show that established constitutive equation and temperature parameters of 07MnNiMoDR steel have good prediction accuracy for predicting rolling force with an R value of 0.9875.
