Embodiment Construction

[0025] The cooling nozzle provided by the invention with continuously adjustable jet flow width is a nozzle used for cooling steel plates, steel strips or other plates. Its structure is as Figure 1 to Figure 4 As shown: it includes a cooling medium pipeline 10, a cooling nozzle 2, and a cylindrical plug 3 connected to the cooling nozzle 2 is inserted at both ends of the cooling nozzle 2 respectively. A transmission rod 4 is provided, one end of which is connected to the cylinder plug 3, and the other end is located outside the cooling nozzle 2. Seals are also provided for the end face sealing of the cooling nozzle 2 and the shaft sealing on the transmission rod 4 .

[0026] Described cooling spray pipe 2 is a steel pipe, and in the region facing the cooling steel plate, there are certain arrangements, a certain number, and certain sizes of spray pipe spray holes 12 ( figure 2 ), for example: one row, the hole spacing is 30mm, and the hole diameter is 3.5mm. The nozzle hol...

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...
