1 前言影响冷轧带钢板形的比较敏感的工艺因素是轧制压力和轧辊凸度的变化。为了控制板形,可以采用改变轧辊凸度的办法,例如改变原始凸度、使用液压弯辊和进行热凸度控制,也可以利用双阶梯支承辊改变轧辊之间接触压力分布,使轧机横向刚性对压力、凸度等变化的依赖关系减弱乃至消除,借以提高板形质最。当所轧产品宽度变化不大时,综合利用双阶梯支承辊,可以用四辊轧机收到HC轧机相似的效果。这对于改造,利用现有四辊旧式轧机,提高板形质量有较大的现
1 Preface Affect the cold-rolled strip shape more sensitive to the process factor is the rolling pressure and roll crown changes. In order to control the shape of the plate, the method of changing the crown of the roll can be adopted, for example, changing the original crown, using the hydraulic bending roll and controlling the thermal crown, and also using the double-step backing roll to change the contact pressure distribution between the rolls and make the rolling machine transverse rigidity Dependency on pressure, convexity and other changes weakened or eliminated, in order to improve the quality of the most form. When the rolled product width changes little, the comprehensive utilization of double-step back-up roller, you can use a four-roll mill to the HC mill similar results. This is the transformation, the use of the existing four-roll old mill, improve the quality of the shape of a larger now
