一、概述目前,国内外冷轧带钢轧机及其生产工艺随着产品产量和质最的日益提高而得到不断改进,轧机刚性明显提高。尽管如此,也很难适应生产宽薄规格钢板的需要,因为刚性再好的轧机也必然有弹跳值。弹跳值的大小与轧制压力有关,即: I. Overview At present, the domestic and foreign cold-rolled strip mill and its production technology with the increasing yield and quality of the product has been continuously improved, significantly improved mill rigidity. In spite of this, it is difficult to adapt to the need to produce wide and thin gauge plates, since even stiffer mills are bound to have bouncing values. Bouncing value of the size and rolling pressure, that is:
