Abstract

The invention discloses an 8006 alloy double-zero foil for household tableware and a preparation method thereof. The method comprises: (1) mixing and melting electrolytic aluminum liquid and aluminum-containing waste to obtain molten aluminum; (2) melting the molten aluminum Refining and slag removal treatment to obtain refined aluminum liquid; (3) adding aluminum-titanium-boron wire refiner to the refined aluminum liquid on-line for refinement to obtain refined aluminum liquid; (4) using inert gas to refine the aluminum liquid On-line degassing and on-line filtration to obtain the final aluminum liquid and refined impurities in the front box; (5) cast and roll the final aluminum liquid to obtain the cast-rolled billet; (6) pass the cast-rolled billet through cold rolling, the first time Annealing, intermediate rolling, second annealing and foil rolling to obtain 8006 alloy double zero foil. The method has the advantages of low energy consumption, low pollution, and low cost. At the same time, the thickness of the 8006 alloy double-zero foil for household tableware produced at the same time reaches 0.006-0.0075mm, the tensile strength is not less than 210MPa, the elongation is not less than 8%, and the surface quality A more excellent production method of aluminum foil for household tableware.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy foil processing and production. Specifically, the invention relates to an 8006 alloy double-zero foil for household tableware and a preparation method thereof. Background technique [0002] Aluminum foil for household tableware has many characteristics such as recycling, strong barrier, resource saving, various heating, sanitation, and safety protection. The main alloys used for aluminum foil for household tableware are 1100, 1145, 8011, 8006, etc. The thickness of the goods is not more than 0.15mm. With the development of economy and technology, the market has higher and higher requirements for household tableware aluminum foil. It is hoped that the thickness of tableware aluminum foil will be further reduced, the tensile strength will be increased, the elongation rate will be further increased, and the surface quality will be more excellent. However, the currently produced aluminum foil ...
