摘要 针对国内某四重铝箔轧机生产装饰箔时出现的二肋浪形问题,根据板形理论分析认为箔材轧制中产生二肋浪形的原因是工作辊对应区域的等效凸度过大.分析了热膨胀和冷却、工作辊粗糙度和工作辊曲线等因素对工作辊等效凸度的影响,确定现场条件下影响工作辊对应区域等效凸度的主要因素为工作辊曲线参数,参考相关文献推导了铝箔轧机工作辊曲线表达式,对采用不同凸度、不同半角时的工作辊曲线进行了对比,从中选出适合当前工况下的工作辊曲线.采用该工作辊曲线进行现场实验,实验结果表明通过提高工作辊曲线半角角度可使二肋浪问题得到解决. Aim at the double-rib wave problem which happened during rolling decoration foil production using a four-high mill in certain domestic factory,according to the shape control theory,this kind of strip shape obtained due to the equivalent convexity in the corresponding area of the working roll was excessive.The effects of the factors such as thermal extension and cooling,the roughness and the curve of the working rolls on the equivalent convexity were analyzed.The key factor affected the equivalent convexity of the corresponding area of the working rolls in the worksite.The expression equations of the curve of the working roll was deduced based on references,and the comparisons were made among the curves with different half-angles and different convexity,respectively,therefore,the optimized curve of the working roll under current working conditions was selected.The double-rib wave problem was eliminated after increased the half-angle of the curve of the working roll in the worksite experiment.
