摘    要：通过比较流体润滑状态下冷轧变形区摩擦系数与轧机允许最小摩擦系数得出轧制稳定因子K_S，用于判断其轧制过程是否稳定。计算与实验结果表明：K_S值随压下率减小而降低，且当K_S<1时出现负前滑及摩擦力反向，同时轧后板面质量变差。因此,只有当压下率达到一定值后，K_S>1，才能实现稳定轧制并获得优异的轧后板面质量。

Abstract: The stable rolling factor K_S was developed to decide the stability of rolling process by comparing the friction coefficient in hydrodynamic lubrication rolling with allowed minimum friction coefficient in rolling. The results in calculations and experiments showed that K_S value reduced with decreasing reduction rate, which caused the negative forward slip and a change of friction direction and a poor rolled surface when K_S< 1. Only reduction rate reached a certain value and K_S>1 can rolling be stable process and good rolled surface quality be obtained.
