3003 Aluminum Foil Company In China
In order to benefit the increasing food consumption, the aluminum foil container manufacturing industry must be promoted to become an important and developed industry. Although the concept of manufacturing thin-walled food containers is simple, it requires high-level pressure processing technology. This not only involves the processing and forming of thin-walled containers, but also the ability to produce containers of various shapes and specifications for the huge consumer market. In order to increase production capacity, a multi-tool combination scheme is currently used, using three or five sets of tools to increase the output of various aluminum foil containers.
3003 Aluminum Foil Company The present invention belongs to the manufacture of aluminum alloy materials, and relates to a method for manufacturing container foils. The method sequentially goes through the following steps: a. smelting, casting and rolling, the aluminum alloy material labeled 3003 is conventionally smelted and cast-rolled, and cast-rolled The thickness of the billet is 7.5-8.2mm; b. The billet is cold-rolled to 3.5-4.5mm and then annealed at a high temperature, the annealing temperature is 560-600℃, and the annealing time is 20-25h; c. The billet after high temperature annealing is passed through Conventional cold rolling and foil rolling to the thickness of the finished product, and then annealed to obtain the final product, the annealing step is: first annealing at an annealing temperature of 200°C for 4-8h, and then annealing at an annealing temperature of 300°C for 12-20h. The inventive method is based on the casting-rolling process to produce container foils, and the mechanical performance indicators of the products obtained can fully meet the use requirements of container foils, and its cost is much lower than that of container foils produced by hot-rolling technology.
The alloy composition and weight percentage of the container foil material are: Si 0.20～0.26%, Fe 0.42～0.50%, Cu 0.05%, Mn 0.15～0.20%, Mg 0.01%, Zn 0.1%, Ti 0.04%, Al balance. The material of the present invention is based on the 8011 alloy, after redistributing the Fe and Si content, and adding a certain Mn element, it can not only improve the strength of the material, but also has better processing performance and is easy to roll. After processing by the method of the present invention, after testing, when the thickness of the aluminum foil is 0.05-0.06mm, the tensile strength is 120-160Mpa, the elongation is ≥12%, the cupping ≥5.0, it has good punching performance and can meet various requirements. Production of tableware for aviation.
