Problems solved by technology

[0003] However, due to some shortcomings in the processing of aluminum alloy profiles, aluminum alloys need to be heat treated during processing. However, there are still defects in the traditional aluminum alloy heat treatment methods. It is not easy to straighten and process it during the treatment process, resulting in uneven thickness and poor flatness on the surface, which in turn affects the later processing and use of aluminum alloys. For this reason, this invention proposes a heat treatment process for aluminum alloy profiles to solve the problem. above question

Abstract

The invention provides a heat treatment process of an aluminum alloy profile, and relates to the field of aluminum alloy profiles. The heat treatment process comprises the following steps of (1) solution treatment, (2) straightening, (3) quenching treatment, (4) cold rolling treatment; and (5) post-treatment. The heat treatment process of the aluminum alloy profile is designed, the required aluminum alloy profile is taken and subjected to heat treatment, that is, the aluminum alloy profile is placed in a high-temperature environment of 950 DEG C-1050 DEG C to be subjected to heat treatment forthe first time, the heat treatment time is 3.3-4 hours, and a second phase or other soluble components in the material are fully dissolved into an aluminum matrix to form a supersaturated solid solution. Then the supersaturated solid solution is kept at the room temperature through a rapid cooling method, the supersaturated solid solution is in an unstable state, solute atoms are likely to be separated out at any time due to the high-energy-level state, the plasticity of the material is high at the moment, a cold machining or straightening procedure can be carried out, and then the processedmaterial is straightened, so that the aluminum alloy profile can quickly reach the shape required by a user.

Description

technical field [0001] The invention relates to the field of aluminum alloy profiles, in particular to a heat treatment process for aluminum alloy profiles. Background technique [0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and fans. They are called aluminum alloy doors and windows, or aluminum doors and windows for short. Aluminum alloy doors and windows include doors and windows made of aluminum alloy as a force-bearing member (a member that bears and transmits its own weight and load) and wood, plastic composite doors and windows, referred to as aluminum-wood composite doors and windows, aluminum-plastic composite doors and windows. The quality of aluminum alloy doors and windows can be roughly judged from the selection of raw materials (aluminum profiles), the surface treatment of aluminum materials, the quality of internal processing, and the price of aluminum alloy doors and windows. ...
