在冷轧机译计中,轧辊直径的选择是极其重要的。产辊直径愈大,为实现已知轧制制度所需的轧制力愈大。相反,轧辊愈小,即便在较低的轧制速度时,轧辊的冷却也愈困难。此外,轧辊大,刚性也就好,在一台四辊轧机上,就能容易获得更好的带材形状。另一方面,轧辊小,操作时轧辊咬入口的摩擦力大,对于轧制润滑条件变化影响的敏感性就降低。由于 In the cold mill translation, the choice of roll diameter is extremely important. The larger the roll diameter, the greater the rolling force required to achieve the known rolling schedule. Conversely, the smaller the roll, the more difficult it is to cool the roll even at lower roll speeds. In addition, the rolls are large and rigid enough to provide better strip shape on a four-roll mill. On the other hand, the roll is small, the operation of the roller bite at the mouth of the friction, the rolling lubrication conditions change sensitivity to reduce. due to
