Example Embodiment

[0011] The embodiments provided by the present invention will be described in further detail:

[0012] An aluminum treatment process, the steps are as follows:

[0013] (1) Blank inspection: inspect the workpiece;

[0014] (2) Degreasing: Degreasing the aluminum material of the workpiece until the workpiece is completely wetted;

[0015] (3) Solution treatment: heat the aluminum material to 950 ~ 1050 ℃ and then water quench it, and keep this state to room temperature;

[0016] (4) Stress relief treatment: heat treatment for tempering at 300 ~ 350℃ to eliminate residual stress of aluminum after cold working or welding;

[0017] (6) Cooling: Use water less than 70℃ to cool the workpiece.

[0018] Preferably, the water-based metal degreasing cleaning agent includes a surfactant, sodium tripolyphosphate, fatty alcohol polyoxyethylene ether and sodium silicate to degrease the surface of the workpiece.

[0019] The beneficial effects of the present invention: low processing cost, long-lasting d...

Abstract

The invention discloses a heat treatment technology for an aluminum product. The heat treatment technology comprises the following steps that firstly, blank checking is conducted, and a workpiece is checked; second, degreasing is conducted, and the workpiece aluminum product is degreased until the workpiece is completely soaked; thirdly, solution treating is conducted, particularly, the aluminum product is heated to 950-1050 DEG C and subjected to water quenching, and the state is kept until the room temperature is reached; fourthly; destressing treating is conducted, particularly, tempering is conducted after heating is conducted to the temperature of 300-350 DEG C, and heat treating of eliminating residua stress obtaineafter cold machining or welding is conducted on the aluminum product; and sixthly, cooling is conducted, and water with the temperature smaller than 70 DEG C is used for cooling the workpiece. The heat treatment technology is low in treating cost, durable in use and capable of improving the technology treating efficiency and the quality of the workpiece.

Description

technical field [0001] The invention belongs to the technical field of heat treatment, in particular to an aluminum material heat treatment process. Background technique [0002] At present, the aluminum steel pipe is a long strip of aluminum with a hollow section and no seams around it. However, the current heat treatment process cannot meet the requirements, which not only wastes resources, but also complicates the process. Contents of the invention [0003] The technical scheme of the present invention is achieved in that a kind of aluminum processing technology, its steps are as follows: [0004] (1) Blank inspection: inspect the workpiece; [0005] (2) Degreasing: Degrease the aluminum material of the workpiece until the workpiece is completely soaked; [0006] (3) Solution treatment: heat the aluminum material to 950-1050°C and quench it in water, and keep this state at room temperature; [0007] (4) Stress relief treatment: heating to 300-350°C and tempering to ...
