Aluminum Foil On Roll
Analysis on the development trend of aluminum foil processing technology and equipment
1. Processing technology is developing towards high efficiency, low cost, low energy consumption and short flow. In order to reduce consumption, reduce processing costs, and improve product quality, the international aluminum foil processing technology continues to improve, and the process continues to shorten. The horizontal continuous casting and continuous rolling process of 3 mm thick aluminum plate introduced by Alcoa, the thin aluminum plate produced can be directly used for punching beverage cans. The new ultra-thin high-speed roll casting mill developed by the Italian FATA Engineering Company is used to produce aluminum heat sinks and aluminum foil wool with a thickness of 1 mm to 1.5 mm and a casting speed of 7.6 m/min to 23 m/min. . It can reduce the thickness of the continuous cast-rolled aluminum slab, improve the internal structure of the cast-rolled sheet and refine the grains, and improve the product quality. At the same time, it can further save energy and reduce consumption, increase production efficiency and reduce costs.
2. New technologies and new equipment are constantly emerging. The preparation of new materials with special conditions such as strong magnetic field, ultra-high temperature, ultra-high pressure, rapid solidification, low temperature and large deformation processing has become an important way to develop high-performance materials. Electromagnetic casting and electromagnetic casting-rolling can significantly improve the quality of ingots or billets; ultra-thin high-speed casting-rolling technology is the secondary development of continuous casting-rolling technology.
The design and manufacture of foil rolling mills are developing in the direction of high speed, wide width and large coil weight, and the rolling mill speed and production efficiency have been further improved. VAI Company has developed technology to solve the problems of threading and coiling of aluminum foil rolling mills, and to a certain extent solves the contradiction between product quality factors and the speed and output of rolling mills. The focus is on the mechanical parts of the rolling mill, such as ironing rolls, strip drying system, and foil feeding system. Successfully solved the problem of the ironing roll as the aluminum foil rolling speed increased, during the aluminum foil coiling process, the coil loosened due to the air entering, and then the rolling speed of the strip was restricted, so that the production capacity of the rolling mill could not be fully utilized. . The developed control software can precisely control the ironing pressure, and the complete drying system guarantees the quality of the finished roll. Optimize the spray mode in the cooling system and strengthen the control of the spray area to ensure the cooling effect and the shape of the foil. The feeding system and the floating platform on the exit side of the rolling mill effectively reduce and speed up the belt threading process. This new technology can also be used to upgrade existing rolling mills.
Aluminum Home Foil Jumbo Roll The minimum thickness of aluminum foil of the lxxx and 8xxx series is 6.3 microns and 8-10 microns, respectively.
