Principles Of Aluminum Foil Rolling Process

1. Determination of total processing rate
The total processing rate refers to the total deformation of the foil after recrystallization annealing to rolling out the finished product. Generally speaking, the total processing rate of 1 series can reach more than 99%, and some 8 series products can also reach this value, but the total processing rate of aluminum alloy foil is generally below 90%.
2. Determination of pass processing rate
The determination of the processing rate of the pass is the core of the rolling process. The processing rate of the pure aluminum series products can reach 65%. In the first pass after the billet is annealed, it is not suitable to use an excessive processing rate, generally 50%. about.
