摘要： 基于普通中厚板四辊轧机,利用影响函数法分析了轧件宽度、轧制力、工作辊和支撑辊尺寸和弯辊力对有载轧辊凸度的影响,并根据大量计算数据进行回归,得出在线有载轧辊凸度计算模型·分析了轧件入口凸度对出口凸度的遗传效果,综合有载轧辊凸度模型和板凸度遗传系数模型得到在线板凸度计算模型·该模型合理地考虑了轧辊变形和轧件横向流动的影响,能够真实反映出口板凸度的大小,计算精度高,是在线板形和板凸度控制的有效工具·

Abstract: The influence function is used to analyze the influences of workpiece width, rolling force, sizes of work/back-up rolls and bending force acting on roll on the crown of loaded rolls of a conventional 4-high plate mill. With lots of data regressed in calculation, an on-line computation model is given for loaded roll crown. Then, the genetic effect of workpiece crown at entry of rolling process on that at exit is discussed, and an on-line prediction model of plate crown is thus given integrating the model of loaded roll crown with that of plate crown's genetic coefficient. The model can predict actually the crown magnitude of rolled plate with high precision because the effect of lateral plastic flow of workpiece in rolling process has been taken into account. So, it is efficient to on-line control of plate shape especially its crown.
