Problems solved by technology

[0003] The production process of the traditional 5182 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 → 3 passes of single-stand cold rolling → middle trimming → 4 passes of single-stand cold rolling → 5 passes of single-stand cold rolling → 6 passes of single-stand cold rolling → tension bending and straightening → coating → finished product shearing; The cold rolling is divided into six passes, which not only takes a long time and has low work efficiency in the rolling process, but also increases the number of times on the machine, which also increases the probability of bruising defects; In addition to rolling tails, material waste also reduces product yield

Abstract

The invention discloses 5182 aluminum alloy cover base material and a production method for the 5182 aluminum alloy cover base material. The production process of the material comprises the steps of casting, sawing, surface milling, soaking, 1+4 hot continuous rolling, three-stand cold continuous rolling, cut side cleaning and single-stand cold rolling. The production method guarantees that the mechanical property of the 5182 aluminum alloy cover base material is stable and qualified, the production procedure 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 5182 aluminum alloy can lid 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 5182 aluminum alloy can lid material is suitable for a wide range of lid types. It can be used to make SOT, RPT, and FA lids of 200-209 lid types, and the thickness is mostly 0.216-0.275mm. It can be used for beverage lids and food without internal pressure or with internal pressure. cover. 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 5182 alloy tank cover material is mostly 0.208mm, 0.216mm, 0.218mm, 0.2...
