八辊可逆式冷轧带钢轧机是五十年代开始使用的一种优点较多的多辊式带钢轧机。由于工作辊的直径比较小,使轧制压力降低,不但降低轧机负荷,也减少轧机弹跳,从而使轧机的可轧厚度减薄。轧机采用大的支承辊传动,以去除传动小直径工作辊的扭力不足。采用侧支承辊以抵销工作辊的有害水平弯曲。在辊系布置中采用工作辊对支承辊的偏心距 e,使轧机具有良好的稳定性,改善了工作辊的刚性,所以这种轧机除轧制精度较高以外,可加大压
Eight-roller reversible cold-rolled strip mill is a multi-roller strip mill with more advantages since the 1950s. As the work roll diameter is relatively small, so that the rolling pressure is reduced, not only reduce the mill load, but also reduce mill bounce, so that mill rolling thickness can be reduced. Rolling mill with a large back-up drive to remove the transmission of small-diameter work roll torque shortage. Side support rollers are used to counteract the detrimental level of work roll bending. In the roller system, the eccentricity e of the work roll to the back-up roll is adopted, so that the rolling mill has good stability and the rigidity of the work roll is improved. Therefore, in addition to the high rolling precision, this kind of rolling mill can increase the pressure
