A kind of high-strength aluminum alloy profile heat treatment process

Abstract

The invention discloses a high-strength aluminum alloy profile heat treatment process in the technical field of aluminum alloy profile heat treatment. The specific steps of the process are as follows: Step 1: inject cooling water into a heat treatment device, so that the water level of the heat treatment equipment reaches the working height; Step 2: The high-temperature aluminum alloy profiles that need to be heat treated are input into the heat treatment device, the heat treatment device is started, and the high-temperature aluminum alloy is heat treated; step 3: after the heat treatment is completed, the aluminum profiles are transferred to the next process; the present invention solves the problem of existing equipment In the process of heat treatment of aluminum profiles, the heat treatment of aluminum profiles is usually carried out by means of spray cooling. Due to the problem of heat treatment dead ends, annular water flow is usually sprayed directly onto the outer surface of the aluminum profiles. Effectively control the cooling time of heat treatment, so that the cooling time of aluminum profiles is too fixed, which leads to the problem of poor equipment applicability.

Description

technical field [0001] The invention relates to the technical field of heat treatment of aluminum alloy profiles, in particular to a heat treatment process for high-strength aluminum alloy profiles. Background technique [0002] Aluminum profile heat treatment is a process in which aluminum profile products are heated to a suitable temperature in a certain medium, and then cooled at different speeds. Heat treatment of aluminum profiles is one of the more important processes in material production. Compared with other processing processes, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but changes the internal microstructure of the workpiece or changes the workpiece. The chemical composition of the surface that imparts or improves the performance of the workpiece. It is characterized by an improvement in the intrinsic quality of the workpiece, which is generally not observable by the naked eye. The "four fires" in the h...

Problems solved by technology

[0005] The object of the present invention is to provide a high-strength aluminum alloy profile heat treatment process to solve the problem that the existing equipment in the above background technology usually adopts the spray cooling method to heat treat the aluminum profile during the heat treatment process of the aluminum profile. The dead angle problem is usually directly sprayed onto the outer surface of the aluminum profile by means of annular water flow, but in order to keep the water flow uniform around the water flow size, the size of the water flow cannot be controlled effectively, and the cooling time of the heat treatment cannot be effectively controlled, resulting in the cooling time of the aluminum profile being too fixed, resulting in poor applicability of the equipment The problem arises; secondly, the supercooled coolant is directly sprayed onto the surface of the aluminum profile, which may cause chapping on the surface of the overheated aluminum profile, and even cause bending problems of the aluminum profile
