The traditional aluminum foil production process mainly relies on hot rolling. This method first smelts raw aluminum into large ingots, and then uniformly heats and hot-rolls them to form billets. Then, through rough rolling, finish rolling and other steps, it is finally processed into finished aluminum foil. Although this process has been widely used, it still has many shortcomings. The entire production process is cumbersome and involves multiple processes, which is both time-consuming and energy-consuming, resulting in low production efficiency. In addition, large deformation stress is easily generated during the hot rolling process, which affects product quality stability and material structure uniformity. Due to the high cost, this also limits the production and promotion of ultra-thin aluminum foil.
