Abstract: This paper mainly analyzes the production process of double-zero aluminum foil, the condition of billet and the level of equipment, and finds out the causes of the production of double-zero aluminum foil pinholes. It takes reasonable control mode to ensure that the number of pinholes of double-zero aluminum foil can be effectively controlled Pinhole in order to facilitate the purpose of improving stability. Fully analysis of double zero aluminum foil pinholes and more formation factors, from various aspects of control, to ensure that can significantly reduce the number of pinholes.

At present, the production of double-zero aluminum foil there are many pinholes, the use of very easy to break, can not fully meet the actual situation, the mainstream of the market today is more high-quality double zero aluminum foil, with a certain market advantage, the urgent need to solve the problem Is to improve the overall quality, effectively reduce the pinhole size, quantity.

Causes and quality control options

Production of aluminum foil to form pinholes have many factors, such as, can not be reasonably allocated rolling pass processing rate, aluminum foil wool quality problems, tension and rolling force does not meet the unreasonable production process, can not reasonably control the surface roughness and roll convex degree. From the rolling oil filtration accuracy, aluminum foil wool quality, production technology and other aspects of the reasons for the pinhole.
