对大型轧机的相同转速、不同直径轧辊的力矩分配进行了理论分析和模拟实验，并由此提出，大型轧机不同辊径等转速带“下压力”轧制时，应考虑锭重和轧件运动加速度对轧制力矩的影响，轧机下辊应选用较大的电机才能充分发挥轧机的能力。 The theoretical analysis and simulation experiment on the torque distribution of the same speed and diameter roller of the large rolling mill are made. It is proposed that the rolling force of the bar load and the rolling stock should be taken into account when the " The influence of acceleration on the rolling torque, the lower roller mill should use a larger motor in order to give full play to the ability of the mill.
