Problems solved by technology

[0006] 8150 alloy is not a conventional aluminum alloy, which contains high manganese. When the alloy is produced by casting and rolling, the manganese segregation in the structure is serious, and the crystal grains are easily coarse in subsequent production, resulting in poor mechanical properties of the finished product and cannot be used.
The reason is that the difference in manganese concentration around the grain and in the grain expands the temperature range of recrystallization, reduces the nucleation rate, and thus easily produces coarse grains.

Abstract

The invention discloses a process for producing an aluminum medium gaugefoil through an 8150 alloy. The process includes the following steps that 1, material proportioning is performed; 2, smelting isperformed; 3, refining is performed; 4, cast rolling is performed; 5, cold rolling is performed; 6, rolling is performed through a rolling mill; 7, thickness shearing is performed; and 8, annealing and packaging are performed. An aluminum medium gaugefoil roll is annealed and cooled through an annealing furnace and then is packaged, and thus a finished aluminum medium gaugefoil is obtained. The aluminum medium gaugefoil produced through the process is excellent in tensile strength, ductility and the like, is not prone to cracking during stamping, is high in yield and meets the using requirement of a container foil.

Description

technical field [0001] The invention belongs to the technical field of aluminum foil production, and more specifically relates to a process for producing single zero aluminum foil from 8150 alloy. Background technique [0002] 8 series aluminum sheet: 8011 aluminum sheet is more commonly used, which belongs to other series. The aluminum plate whose main function is to make bottle caps is also used in radiators, most of which are aluminum foils. [0003] 8150 aluminum alloy has medium strength, high plasticity, excellent cupping performance, and is easy to form by stamping. The plate is used to produce anti-glare dome lights, low dome lights, and embedded dome lights; its aluminum foil finished products are mainly used for aviation fast food utensils and aviation food packaging, and there is a tendency to gradually replace other grades of alloy food packaging materials; [0004] Single zero foil is a foil with a thickness of 0.01mm or less than 0.1mm. Single zero foil is wi...
