Problems solved by technology

[0003] The production process of the traditional 5052 alloy can lid material base material is: melting and casting → sawing → milling → soaking → (1+4) hot continuous rolling → single-stand cold rolling 1 pass → single-stand cold rolling 2 passes → Edge trimming in the middle → 3 passes of cold rolling on a single stand → 4 passes of cold rolling on a single stand → stretching and straightening → coating → finished product shearing; the aluminum alloy is rolled in four passes in cold rolling, not only It takes a long time, low work efficiency, and increases the number of times on the machine, which also increases the probability of bruising defects; at the same time, due to the repeated removal of rolling tails during the cold rolling process, material waste also reduces the product yield

Abstract

The invention discloses a production method of a 5052 aluminum alloy tank cover base material. The production method of the 5052 aluminum alloy tank cover base material comprises the steps of melting and casting, sawing, surface milling, soaking, (1+4) hot continuous rolling, three-rack cold continuous rolling, cut edge cleaning, and single-rack cold rolling. By the adoption of the production method, it is guaranteed that the mechanical property of the 5052 aluminum alloy tank cover base material is stable and qualified; in addition, the production process is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of aluminum alloy manufacturing, in particular to a production method of a 5052 aluminum alloy can lid material base material. Background technique [0002] 5052 and 5182 alloys are used for can lid materials, and the 5052 alloy has a low magnesium content. It is an early alloy and was finalized in the late 1920s. At present, the 5052 aluminum alloy can lid material is suitable for a wide range of lid types, and the thickness is mostly 0.22-0.27mm. It is used for beverage lids and food lids without internal pressure, while 5182 is mostly used for beer lids with internal pressure. In the production of cans, it is the goal of the lid industry to minimize the thickness of the sheet, improve the elongation and strength of the product, improve the utilization of materials, and reduce production costs. At present, the thickness of 5052 alloy tank cover material is mostly 0.22mm, 0.238mm, 0.24mm, 0.244mm, 0.25mm, 0.253mm, 0...
