Embodiment Construction

[0016] The present invention will now be further described with reference to the drawings and specific embodiments.

[0017] reference figure 1 , figure 2 , This embodiment provides a rapid cooling method for an aluminum profile extrusion online quenching process, which includes the following steps:

[0018] In the first step, after the aluminum profile 9 passes through the heating ring 8, it is sent to the first cooling area. A plurality of first spray devices 1 are arranged in the first cooling area, and each first spray device 1 is evenly distributed to form an arc-shaped channel , The particle size of the water mist sprayed by each first spray device 1 is not greater than 10 μm, and a first suction fan 2 for sucking water mist particles is provided under each first spray device 1 in the first cooling area;

[0019] In the second step, it is sent to the second cooling area, where a plurality of second spray devices 3 are arranged, and each second spray device 3 is evenly distrib...

Abstract

The invention relates to the field of aluminum profile making, in particular to a quick cooling method of an aluminum profile extrusion on-line quenching process. The quick cooling method of the aluminum profile extrusion on-line quenching process comprises the following steps of firstly, sending an aluminum profile into a first cooling area after the aluminum profile passes through a heater ring,wherein first spraying devices of a plural number are arranged in the first cooling area, the particle size of water mist is no larger than 10 microns, and a first suction fan for sucking water mistparticles is arranged in the first cooling area; secondly, sending the aluminum profile into a second cooling area, wherein second spraying devices of a plural number are arranged in the second cooling area, the particle size of water mist is no larger than 100 microns, and a second suction fan for sucking water mist particles is arranged in the second cooling area; and thirdly, sending the aluminum profile into a third cooling area, wherein third spraying devices of a plural number are arranged in the third cooling area, and the particle size of water mist is no larger than 400 microns. Withthe quick cooling method of the aluminum profile extrusion on-line quenching process, the technical problems that according to an existing on-line quenching process, quick cooling cannot be carried out, and the stability of an aluminum profile subjected to quenching cannot be guaranteed are solved.

Description

Technical field [0001] The invention relates to the field of aluminum profile production, in particular to a rapid cooling method of an aluminum profile extrusion online quenching process. Background technique [0002] At present, the process of online quenching of aluminum profiles is relatively mature, but how to perform rapid cooling after quenching and maintaining the quality of aluminum profiles during the cooling process is still a problem that the industry has been exploring. Chinese Patent No.: 201520158994.X discloses an air mist cooling device for improving the on-line quenching strength of extruded aluminum alloy. The frame, the frame, the water tank, and the conveying roller; the frame is provided with a support part; the support part It includes a vertical support foot and an oblique support foot, which form a triangular support seat; an upper overflow groove is fixed on one side of the frame; a water tank is arranged on the other side of the frame, and the water tan...
