Problems solved by technology

The aluminum alloy is cold-rolled in five passes, which not only takes a long time and reduces work efficiency, but also increases the number of machines, which also increases the probability of bruising defects and the risk of surface quality defects ; At the same time, due to the repeated removal of the head and tail materials in the cold rolling process, material waste is caused, which reduces the yield of the pull ring material

Description

technical field [0001] The invention relates to the field of aluminum alloy manufacturing, in particular to a production method of a 5182 aluminum alloy pull ring material base material. Background technique [0002] The 5052 and 5182 alloys are used for pull ring materials. The 5052 alloy has a low magnesium content and is an early alloy. The 5182 alloy is an alloy with a high magnesium content. The pull ring products produced by the 5182 alloy have performance stability and use Wider range. In the production of pull ring materials, it is the goal of the cover industry to minimize the thickness of the sheet metal, improve the elongation and strength of the product, improve the utilization rate of the material, and reduce the production cost. At present, the thickness of tab material is 0.267mm, 0.279mm, 0.29mm, 0.305mm, 0.36mm, 0.38mm, 0.405mm, 0.457mm, 0.46mm. The mechanical properties put forward higher requirements; at the same time, with the continuous development of ...
