Fog-cooling system for heat treatment for stainless steel strip

Abstract

The invention discloses a fog-cooling system for heat treatment for a stainless steel strip. The system comprises a plurality of filters, a multi-stage high-pressure centrifugal pump and a high-pressure atomization spray head, wherein an inlet of the multi-stage high-pressure centrifugal pump is connected with the plurality of filters in parallel through water pipes, and running water is filteredand then conveyed to the multi-stage high-pressure centrifugal pump and pressurized; an outlet of the multi-stage high-pressure centrifugal pump is connected with the high-pressure atomization spray head through a water pipe, and the pressurized high-pressure water is conveyed into the spray head and sprayed out; the interior of the high-pressure atomization spray head is a cavity, and a pluralityof nozzles are formed in the bottom surface of the high-pressure atomization spray head; and a double-spiral spray channel is formed in each nozzle, and the bottoms of the spray channels are gatheredto form a spray hole with an inner diameter of 1 mm, so that the sprayed high-pressure water is in a fog state. The fog-cooling system aims at making up for the deficiencies of the prior art. The running water is pressurized through the high-pressure pump and sprayed out through the small-hole-diameter nozzles to form the fog state, so that the atomization effect is effectively improved, and theproduction cost is lowered.

Description

technical field [0001] The invention relates to a mist cooling treatment system, in particular to the mist cooling system used in the mist cooling section after the annealing treatment of stainless steel strips. Background technique [0002] In the field of stainless steel processing, after the annealing treatment, the stainless steel strip needs to be cooled by air and mist. Stainless steel belt temperature, the most common fog cooling section system is to use compressed air mixed with water to spray to form atomized water. This kind of system needs a lot of compressed air during use, which will easily cause the compressor to operate at full load, resulting in compression force As a result, the supply of compressed air during the atomization process is insufficient, resulting in poor atomization effect. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to make up for the deficiencies of the prior art, and to provide a mist cooli...

[0002] In the field of stainless steel processing, after the annealing treatment, the stainless steel strip needs to be cooled by air and mist. The temperature of the stainless steel belt, the most common fog cooling section system now is to use compressed air mixed with water to spray to form atomized water. This system requires a large amount of compressed air during use, which will easily cause the compressor to operate at full load, resulting in compression force As a result, the supply of compressed air during the atomization process is insufficient, resulting in poor atomization effect
