摘　　要：根据四辊铜带可逆冷轧机的结构和运行特点,在正向及逆向轧制情况下对轧机机架内工作辊系的稳定性进行计算;分析了不同张力情况下的辊系稳定性结果;由于工作辊万向接轴通常存在倾角,文章考虑了该倾角在轧制过程中对工作辊系的扰动,计算其附加力矩对辊系的稳定性影响,并通过对上述计算结果综合考虑,给出了轧制中辊系不稳定现象的解决方法。Based on the structural and operational characteristics of conventional 4- high reversing cold mill for copper strip,the paper presented stability calculations of work roll assembly in forward and backward directions; it analyzed the stabilities under various tensions; it demonstrated the impact of extra torque on the stability in light of disturbance due to inclination angle of universal joint shaft; and it also provided the solutions based on overall consideration.
