Problems solved by technology

[0004]Due to the widespread use of aluminum alloys, many fields with different needs put forward higher requirements for aluminum alloy materials, including composite layer aluminum alloy and coated aluminum alloy Use and processing requirements, currently the composite layer aluminum alloy is mostly produced by drawing casting process, the limitation of drawing casting process itself makes its production discontinuous, while the production process of coated aluminum alloy is spraying or electroplating, its continuous production performance is poor, Therefore, when the composite layer aluminum alloy needs to be coated, it needs to be drawn and cast before a separate coating treatment. The production process is complicated and time-consuming, resulting in high production costs.

Description

technical field [0001] The invention belongs to the field of processing aluminum ingots, and in particular relates to a processing technology for aluminum alloy ingots. Background technique [0002] Casting aluminum alloy is to fill the casting mold with molten metal to obtain the aluminum alloy of parts of various shapes. It has the advantages of low density, high specific strength, good corrosion resistance and casting process, and is less restricted by the structural design of parts. Divided into Al-Si and Al-Si-Mg-Cu-based medium-strength alloys; Al-Cu-based high-strength alloys; Al-Mg-based corrosion-resistant alloys; Al-Re-based heat-strength alloys. Most of them require heat treatment to achieve the purpose of strengthening the alloy, eliminating the internal stress of the casting, stabilizing the structure and the size of the part. It is used to manufacture beams, gas turbine blades, pump bodies, pylons, hubs, air intake lips and engine casings, etc. It is also us...
