冷轧轧制力计算模型是过程控制的核心和基础，而轧制力计算的基础为变形抗力，因此提高变形抗力计算精度是提高轧制力计算精度的一条有效途径。为此，笔者首先通过实际轧制力数据反算变形抗力，然后使用数据分析软件对变形抗力进行曲线拟合。由于根据曲线拟合公式计算出的轧制力与实际轧制力存在差距，因此为了提高轧制力的设定精度，根据带钢压下率对轧制力进行了补偿。现场实际应用证明，这种方法能有效提高轧制力设定精度。

Rolling force calculation model is the core and foundation of process control in cold rolling. The accuracy of rolling force calculation is based on the deformation resistance model,so the precision of deformation resistance parameters is very important. The actual data is used to determine the param-eters of deformation resistance. Compared with the actual rolling force,the calculated rolling force with these parameters is not perfect. In order to improve the accuracy of rolling force setup value, rolling force compensation is provided. Field application result shows that the accuracy of rolling force setpoint is improved effectively.
