Cooling spray pipe with continuously adjustable jet width

Abstract

The invention relates to a cooling spray pipe with continuously adjustable jet width, which comprises a cooling medium pipeline (10) and a cooling spray pipe (2), wherein cylinder plugs (3) which are movably connected with both ends of the cooling spray pipe (2) are inserted into the two ends; a transmission rod (4) is arranged, wherein one end of the transmission rod is connected with the cylinder plugs (3) and the other end thereof is arranged outside the cooling spray pipe (2) and is connected with a transmission sprocket wheel (5); and a sealing device is also arranged and used for the end surface sealing of the cooling spray pipe (2) and the shaft sealing of the transmission rod (4). The cooling spray pipe with the continuously adjustable jet width mainly has the advantages of having simple structure, facilitating manufacturing and installation, simply deploying a water pipeline, continuously regulating the jet width, being adapted to the quenching and the cooling of steel sheets with different width, effectively reducing the waste of cooling water, reducing the energy consumption of a water treatment system, controlling the water flow on the surface of the steel sheets, effectively preventing the super-cooling of the sides of the steel sheets, and ensuring the lateral uniformity during a steel sheet cooling process.

Description

technical field [0001] The invention relates to the field of quenching and cooling, in particular to a cooling nozzle with continuously adjustable jet width. Background technique [0002] At present, the medium and thick plate quenching machine and other quenching and cooling equipment generally adopt the nozzle cooling system, that is, the cooling nozzle. Taking the quenching machine as an example, cooling nozzles are used in the low-pressure cooling zone and part of the high-pressure cooling zone. The cooling nozzle adopts the form of directly drilling or installing a nozzle on the seamless steel pipe, so that the cooling medium is sprayed to the upper and lower surfaces of the steel plate at a certain angle and a certain density to cool the steel plate. The cooling nozzle includes an upper nozzle and a lower nozzle, which are respectively used for cooling the upper and lower surfaces of the steel plate. The upper nozzle includes two types: integral cooling nozzle and se...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a cooling nozzle with continuously adjustable jet width, so as to solve the problem that the jet width of the integral cooling nozzle cannot be adjusted, and solve the problem that the spray width of the segmented cooling nozzle can only be adjusted in stages. And the resulting waste of energy in the water treatment system and the problem of affecting the quality of the steel plate due to the overcooling of the edge of the steel plate
