Description

Technical Field

[0001] The utility model relates to the technical field of annealing furnaces, in particular to an annealing device for producing aluminum alloy profiles for doors and windows. Background Art

[0002] Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, maintaining it for a sufficient time, and then cooling it at an appropriate speed. Annealing is a heat treatment process for materials. Aluminum alloy profiles for doors and windows need to go through annealing during the production process to reduce deformation and cracks. After heating and heat preservation, aluminum alloy doors and windows need to be cooled gradually to room temperature or to a certain specified temperature before being taken out for natural cooling. Generally, a fan is used to let the outside air pass into the annealing furnace for cooling, but impurities in the outside air are blown onto the workpiece, reducing the quality of the workpiece. In addition, natural cooling is used after annealing, and the cooling speed is slower based on slow cooling.

[0003] In the prior art, a Chinese utility model patent document with publication number CN217077674U and publication date July 29, 2022 is proposed to solve the above-mentioned technical problems.
