在现代计算机控制的带钢生产中,轧制力的设定极其重要。根据宝钢轧制力模型和现场实测数据,结合热连轧过程中带钢三维变形和热力耦合的特点,应用DEFORM-3D软件建立了带钢热连轧前两个道次的有限元模型,模拟了热连轧过程中两个道次的轧制力变化,并与宝钢模型计算值和实测值进行了对比。结果表明,有限元法计算的轧制力与现场实测数据接近,两者误差在5.0%以内,同时有限元法的计算精度高于宝钢轧制力模型,特别是在第一道次,轧制力计算精度高出4.0%,该模拟为现场轧制工艺参数的调整优化提供了重要的参考价值。

In modern computer controlled strip steel production,the prediction of rolling force is very important.Based on the rolling force model and field data of Baoshan steel plant,then associated with the features of three dimensional deformation and thermo-mechanical coupling in continuous hot strip rolling process,the finite element model of the first two passes in continuous hot strip rolling process was established by using the DEFORM-3D software.The rolling forces of the two passes were simulated and then contrasted with the calculated values of Baoshan steel plant model and measured values.The result shows that the rolling forces calculated by the finite element method are close to the measured data,their errors are less than 5.0%;meanwhile,the accuracy of the finite element model is higher than that of the Baoshan steel plant model,especially at the first pass,the accuracy of the rolling force is 4.0% higher than that of Baoshan steel plant model;this simulation can provide an important reference to the optimization of field process parameters.
