Double Zero Aluminum foil Jumbo roll factory price
The principle of the double zero foil finish annealing system is usually the purpose of double zero foil annealing, one is to obtain a certain degree of plasticity; the other is to obtain a bright, clean and oil-free surface quality.
The main parameter of the annealing process is the annealing time, which mainly depends on the amount of the furnace, the width of the foil and the diameter of the coil. The larger the furnace load, the larger the coil diameter and the wider the foil, the longer the annealing time. Under the premise of degreasing effect, the lower the annealing temperature, the better, without having to consider whether the aluminum foil is sufficiently recrystallized. Meeting user requirements is the basis for developing new annealing.
The annealing test of the aluminum foil was performed in a circulating air furnace. In order to eliminate the defects of aluminum foil rolls, slow heating and slow cooling are required, and a step heating system is adopted. The annealing temperature was tested according to the diameter of the aluminum foil and the width of the aluminum foil. The mechanical properties of the aluminum foil, the adhesion of the aluminum foil, and the degreasing performance of the aluminum foil were examined according to different annealing temperatures.
