Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting machine equipment, in particular to a high-efficiency multi-directional rolling mill steel strip blowing device. Background Art

[0002] As competition among domestic steel companies intensifies, the market's requirements for the company's product quality, mechanical properties and automation procedures will become increasingly higher.

[0003] The steel strip is washed with heated hydrochloric acid to remove the oxide scale on its surface, and then washed with high-pressure water to complete the surface cleaning. However, a large amount of water impurities and some residual garbage will remain on the surface of the plate. This requires a purge solution to deal with it. However, due to different specifications of steel strips and the position offset during production, traditional purge devices cannot completely clean the residue on the surface of the plate. If a large amount of water impurities and residual garbage remain on the surface of the steel strip, it will cause it to rust and affect the next process, thereby affecting the production quality of the steel strip. Utility Model Content

[0004] The utility model aims to provide a high-efficiency multi-directional rolling mill steel strip blowing device with simple structure, high blowing efficiency, multi-directional coverage and wide spray range, so as to solve the problems in the prior art.

[0005] The technical solution of the utility model is: a high-efficiency multi-directional rolling mill steel strip purging device, the purging device comprises a purging main pipe, air inlet joints are respectively arranged at both ends of the purging main pipe, mounting plates are respectively arranged on one side of the air inlet joint, the mounting plates are fixedly connected to the two sides below the purging main pipe, a plurality of nozzle joints are evenly connected to the lower part of the purging main pipe, and the lower part of the nozzle joint is threadedly connected to the spray core through a threaded sleeve.

[0006] Preferably, the nozzle joint is threadedly connected to the lower part of the purge main pipe.

[0007] Preferably, the inner wall of the riser is processed into a cone shape.

[0008] Preferably, the outer wall of the riser core is evenly cut with six vertical notches.

[0009] The utility model has the following beneficial effects: simple structure, high purging efficiency, multi-directional coverage, and wide spraying range. Compressed air enters the purging main pipe from the air inlet joints at both ends, and is then distributed to each nozzle joint by the purging main pipe. The compressed air passes through the six tapered slits of the spray core and is evenly sprayed in a cone shape to the surroundings. BRIEF DESCRIPTION OF THE DRAWINGS
