Ingot hot rolling method of Big rolls of aluminum foil
First, the Big roll of 8011 aluminum foil raw material melt is cast into a flat ingot, and then after homogenization, hot rolling, cold rolling, intermediate annealing and other processes, it is continued to be cold rolled into a plate with a thickness of about 0.4~1.0 mm as a foil blank. (Casting → hot rolling and blanking → cold rolling → foil rolling).

In the ingot hot rolling method, the hot-rolled billet is first milled to remove defects such as the oxide layer and impurities on the surface of the ingot, and then the microstructure of the ingot is made more uniform through homogenization, and then hot rolling, cold rolling and intermediate Annealing and other multiple processes. After many times of recovery and recrystallization, the internal structural uniformity and grain size of the billet have been significantly improved. Therefore, hot-rolled billets are usually of good quality and are suitable for high-quality double-zero aluminum foil and aluminum foil products for deep processing. 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 8011 3003 aluminum foil Large roll.
