摘　　要：以2250热轧精轧F1为背景,介绍了轧制力和轧制速度对油膜厚度的影响,并通过现场实测数据处理推导出速度—油膜厚度补偿关系方程,轧制力补偿系数方程。提出了一种简单实用的油膜厚度补偿计算曲线方程,兼顾了油膜厚度、轧制力和轧制速度之间的耦合、非线性关系,同时减少了常用的线性插值法带来的误差。使用上述补偿方法的实际轧制模型对轧件头部厚度的控制效果特别明显。In the context of 2250 hot-rolled finishing mill F1,the effect of rolling force and rolling speed on oil film thickness are introduced,and the equation of speed-oil film thickness compensation relationship and the equation of rolling force compensation coefficient are deduced by processing the actual measured data in the field.A simple and practical oil film thickness compensation calculation curve equation is proposed,which takes into account the coupled,nonlinear relationship between oil film thickness,rolling force and rolling speed,while reducing the errors caused by the commonly used linear interpolation method. The actual rolling model using the above compensation method is particularly effective in controlling the head thickness of the rolled part.
