In the production of double foils, the rolling of aluminum foil is divided into three processes: rough rolling, intermediate rolling and finishing rolling. From a technological point of view, it can be roughly divided according to the thickness of the rolling exit. The general classification method is that the exit thickness is greater than Or equal to 0.05mm is rough rolling, the exit thickness between 0.013 and 0.05 is medium rolling, and the single finished product and double rolled finished product with exit thickness less than 0.013mm are finish rolling.
The rolling characteristics of rough rolling and aluminum plate and strip are similar. The thickness control mainly depends on the rolling force and post-tension. The thickness of rough rolling is very small. Its rolling characteristics are completely different from the rolling of aluminum plate and strip. It has the characteristics of aluminum foil rolling. of particularity.
