Aluminum Paper Paper Roll

In the ingot hot rolling method, the Aluminum Paper Paper Roll is first milled to remove defects such as the oxide layer and impurities on the surface of the ingot, and then homogenized to make the microstructure of the ingot more uniform, followed by hot rolling, cold rolling and After multiple processes such as intermediate annealing and multiple recovery and recrystallization, the internal structural uniformity and grain size of the billet have been significantly improved. Therefore, hot-rolled billets are usually of better quality and are suitable for high-quality double-zero aluminum foil and deep processing. Use aluminum foil products. However, hot-rolled blanks have problems such as high ear yield, easy cracking, and uneven deformation areas during the deep drawing process, which restricts the improvement of the yield of high-quality aluminum foil.
