The smaller thickness of aluminum foil produced by belt production method can reach 0.0025mm and the width can reach 1800 mm. Aluminum foil rolling is roll gap free rolling, and the roll is always in elastic flattening state. During rolling, the thickness of foil is controlled by adjusting rolling force, rolling speed and controlling tension. During rough rolling, the thickness of foil is controlled by rolling force; During finish rolling, the thickness of foil decreases with the increase of rolling speed; The greater the tension, the smaller the thickness; In order to prevent fragmentation, the tension is usually the conditional yield strength of the foil σ 0.2 ~ 0.4 of 0.2. In low-speed rolling, “thick oil” or “thin oil” is often added to the lubricating oil to adjust the rolling thickness of aluminum foil.
Lubricant and roll state have a very important influence on the quality of foil. Aluminum foil blank comes from cold rolled aluminum coil, which is generally pre annealed at 340 ~ 480 ℃, and its thickness is 0.4 ~ 0.7mm. During rolling, the pass deformation rate is about 50%, and the total deformation rate can reach more than 95%. The foil with finished product thickness less than 0.01 ~ 0.02mm shall be rolled and double folded
According to the thickness, it can be divided into
- Double zero aluminum foil ( supper thin: 0.005mm – 0.009mm )
- Single zero aluminum foil ( 0.01mm – 0.99mm )
- Thick aluminum foil ( 0.1mm – 0.2mm )
