Abstract

The invention relates to a production method of aluminum plates and aluminum strips for cosmetic mirror surface aluminum caps. The manufacturing process comprises the steps of smelting, casting, homogenizing treatment, hot rolling, cold rolling, intermediate annealing and cold rolling of finished products. In the smelting process, a bottom-mounted electromagnetic stirring system is adopted; in the casting process, an automatic speed regulation system is adopted; in the hot rolling system, a hot rough rolling pass automatic distribution system is adopted; and in the intermediate annealing system, a large natural gas furnace is adopted for annealing. Through cooperation of all the procedures, product ingredients can be made uniform, and finished products are uniform in surface roughness, fine, smooth, good in smooth finish, free of surface defects such as stripes, black lines and color difference; the mirror surface effect is good after materials are subjected to anodic oxidation and electroplating, and the application requirements for deep drawing and tensile properties of the aluminum plates and the aluminum strips for the cosmetic mirror surface aluminum caps are met.

Description

technical field [0001] The invention relates to an aluminum alloy and a production method thereof, in particular to a production method of an aluminum plate and an aluminum strip for an aluminum mirror cover of cosmetics. Background technique [0002] Aluminum caps made of aluminum alloy are the raw materials for high-end cosmetic bottle caps, and cosmetic bottle caps are generally mirror aluminum caps. General requirements for mirror aluminum cover: high brightness after oxidation, good coloring effect, smooth surface after stamping, low ear-making rate, etc. At present, the ordinary mirror aluminum cover in the market is a 1070H12 state product. Due to the high content of Si and Fe impurities in the composition of the 1070H12 product, segregation is prone to occur during casting and subsequent production, resulting in uneven grain size of the material, and the material is easily oxidized after anodic oxidation and electroplating. Surface defects caused by material texture...
