Production method and system of aluminum alloy plates

Abstract

The invention provides a production method of aluminum alloy plates, comprising the following steps of: decoiling aluminum alloy plates by a decoiler to obtain aluminum alloy tapes; cleaning the aluminum alloy tapes for the first time; enabling the aluminum alloy tapes to pass through an air cushion furnace at a set speed, performing continuous annealing in the air cushion furnace, wherein the temperature of a heating section of the air cushion furnace is a set annealing temperature, and the temperature of a holding section of the air cushion furnace is a set cooling temperature; cleaning the aluminum alloy tapes for the second time; performing stretch leveling on the aluminum alloy tapes by a stretcher leveler; coiling the aluminum alloy tapes by a coiler to obtain aluminum alloy coils; and cutting the aluminum alloy coils to length in a transverse cutting unit to obtain finished products of aluminum alloy plates. The production method of aluminum alloy plates reduces scratches, oil stain and aluminum ash residue on the surfaces of the aluminum alloy plates, and meets the requirements on surface quality of aluminum alloy plates for electrommunication control cabinets. The invention also provides a production system of the aluminum alloy plates.

Description

technical field [0001] The invention relates to the technical field of manufacturing electronic communication control cabinets, and more specifically relates to a method and system for producing aluminum alloy plates. Background technique [0002] With the rapid development of the electronic communication industry, the requirements for electronic communication equipment are getting higher and higher. Among them, the quality requirements for aluminum alloy plates used in electronic communication control boxes have increased. [0003] Aluminum alloy sheets for electronic communication control cabinets need to be sprayed. Scratching, oil stains and aluminum dust residues on the surface of aluminum alloy sheets will affect the spraying effect. Therefore, the surface quality requirements for aluminum alloy sheets for electronic communication control cabinets are high. That is, the surface of the aluminum alloy plate used for the electronic communication control case shall not hav...

Problems solved by technology

[0015] The existing coil production adopts coil annealing, so in the process of annealing, since the aluminum strip is a coil, the oil on the surface of the aluminum strip is not easy to volatilize, and it is easy to cause oil stains to form oil spots; at the same time, when the coil is cleaned, the coil The aluminum ash residue on the coil is not easy to clean, resulting in more aluminum ash residue on the coil

The above method ultimately leads to low surface quality of the aluminum alloy sheet, which cannot meet the surface quality requirements of the aluminum alloy sheet for electronic communication control cabinets

[0016] In addition, in the block production process, the production cycle is longer, which ultimately reduces the production efficiency of the aluminum alloy sheet; in the coil production process, the cooling time required for coil annealing is longer, which ultimately reduces the aluminum alloy sheet.
