Finally, the torsion vibration nature frequency and torque amplitude factor of a rolling mill are calculated by using finite element method. 最后使用有限元法计算了某钢厂冷轧机主传动轴系的扭振固有频率和转矩放大系数。
It is believed that properties of the emulsified rolling oil will have a direct influence on the preductivity of the cold rolling mill and quality of the roled preducts. 轧制油乳化液直接影响到冷轧机的产量及产品质量。
