Problems solved by technology

[0003] Aeronautical structural parts are more stringent in the heat treatment process than general industrial structural parts. For example, in order to meet the material performance requirements, they need to be quenched and annealed immediately after reaching a certain temperature. However, general heat treatment equipment first heats the structural parts from the furnace. It is taken out in the follow-up operation, which misses the best time, and there is no corresponding processing technology

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] Such as Figure 1-Figure 6 As shown, the heat treatment process for composite aeronautical structural parts includes the following steps. First, hang the composite aeronautical structural parts with cleaned surfaces one by one into the heat treatment equipment, heat up to 960-1000°C, and control the holding time at 60°C. -150min; then cool to 805-850°C, control the holding time at 100-200min; finally cool the oil to 60-80°C, take out the structural part...

Abstract

The invention discloses a heat treatment process for composite aviation structural parts, which is characterized by comprising the following steps: firstly, hanging the composite aviation structural parts with cleaned surfaces into heat treatment equipment one by one, heating to 960-1000 DEG C, and controlling the heat preservation time to be 60-150 minutes; then cooling to 805 to 850 DEG C, and controlling the heat preservation time to be 100 to 200 minutes; and finally, carrying out oil cooling to 60-80 DEG C, and taking out the structural part.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a heat treatment process for composite aerospace structural parts. Background technique [0002] Heat treatment refers to a metal thermal processing process in which the chemical composition and structure of the surface or interior of the material are changed by means of heating, heat preservation and cooling in the solid state to obtain the required properties. [0003] Aeronautical structural parts are more stringent in the heat treatment process than general industrial structural parts. For example, in order to meet the material performance requirements, they need to be quenched and annealed immediately after reaching a certain temperature, while the general heat treatment equipment first heats the structural parts from the furnace. The internal removal is in the follow-up operation, which misses the best time, and there is no corresponding processing technology. Cont...
