摘　　要：对铝箔坯料状况、生产工艺、装备水平等进行探讨分析,找出导致铸轧坯料轧制生产双零铝箔针孔原因,采取相应的控制方法,使双零铝箔针孔数得到了有效的控制,降低铝箔"针孔度",达到提高铝箔质量稳定性的目标。对铝箔针孔偏多的原因进行探讨,并从铝箔坯料状况、装备水平、轧辊表面粗糙度、轧制油的过滤精度等方面进行控制,使双零铝箔针孔数大幅度降低断头率也相应减少。This paper analyzes the condition of the aluminum foil slab material,the production technology and equipment level,and finds out the reason that causes the casting slab material produce the double zero aluminum foil pinhole.In this paper the quantity of the double zero aluminum foil pinhole gets effectively control by using relative control method and lower 'pinhole degree' of the aluminum foil to reach the task of improving the quality stability of aluminum foil.This paper analyzes the reason of pinhole exiting.Control has been carried from the situation of aluminum foil slab material,equipment level,rolled surface roughness and filter precision of rolling oil and so on,so that the number of pinhole of double zero aluminum foil has been reduced as well as the endbreaking rate.
