The total processing rate of the total processing rate of ① refers to the total deformation degree 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%, some 8 series of products can also reach this value, but the total processing rate of aluminum alloy foil is generally less than 90%.

② the determination of the processing rate of the road secondary processing rate is the core of the rolling process, pure aluminum series products, its road processing rate can reach 65%, billet annealing after the first time, it is not appropriate to use too large processing rate, generally take about 50%.

Rolling thickness The thickness measurement method of aluminum foil rolling mainly has eddy current measurement thickness, isotope ray thickness measurement and X-ray measurement thickness. X-ray thickness measurement is one of the most common thickness measurement methods used in aluminum foil production, especially in high-speed aluminum foil mill. Thickness control method for aluminum foil rolling: rolling force control, tension control, rolling speed control, tension/speed, speed/tension control.
