在所有开坯机上,当电动机向工作辊传递扭矩时,其万向接轴和联轴节会产生扭转应变。这种扭转应变量取决于工作辊轧制钢锭时所做的功、钢锭和轧机零部件的物理参数,以及传动系统动态特性引起的周期应变量。轧机零部件所承受的应变过大,可能导致严重损坏或疲劳断裂。轧机操作者必须了解扭转应变及其产生的原因,以便在不需要特别维修和停机情况下,充分发挥轧机的潜力。在理想情况下,为了使预定产品的压下量
On all blanks, the torsion strain is generated in the gimbal shaft and the coupling when the motor transmits torque to the work rolls. The amount of torsional strain depends on the work done at the work rolls during the ingot rolling, the physical parameters of the ingot and mill components, and the amount of periodic strain caused by the dynamics of the transmission. Too much strain on mill components can cause serious damage or fatigue fracture. Rolling mill operators must understand the causes of torsional strain and their occurrence in order to take full advantage of the mill’s potential without requiring special repairs and downtime. In the ideal case, in order to make a predetermined product reduction
