Abstract
A cold-rolling strip steel blowing nozzle belongs to the technical field of rolling steel air wipers and meets the requirement of edge blowing during wet temper rolling of a cold-rolling strip steel. The technical scheme of the cold-rolling strip steel blowing nozzle includes that the blowing nozzle comprises a nozzle body, a main air duct, a main blowing port and a plurality of auxiliary blowing ports. The main air duct is positioned on a central axis line of the nozzle body, and the main blowing port and the auxiliary ports are connected between the front end of the main air duct and the front end surface of the nozzle body. The main blowing port is positioned on a central axis line of the main air duct, the auxiliary blowing ports is evenly distributed on the periphery of the main blowing port and the outer edges of the auxiliary blowing ports are tangent to the rim of the main air duct. The cold-rolling strip steel blowing nozzle blows up temper rolling liquor on a surface of strip steel and leads the temper rolling liquor to be subjected to high-speed motion, and the auxiliary blowing ports can keep the high-speed motion of the temper rolling liquor until the temper rolling liquor is blown away from the surface of the strip steel completely and simultaneously, airflow blown out by the auxiliary blowing ports can prevent the temper rolling liquor from splashing. Only 0.4-MPa pressure is needed, so that operating pressure of an air compressor and energy consumption are reduced, besides, the cold-rolling strip steel blowing nozzle is low in price so that cost is greatly reduced.
Description
Technical field
The utility model relate to a kind of cold-strip steel wet use when smooth blow the limit nozzle, belong to steel rolling air purge equipment technical field.
Background technology
Wet when smooth at cold-strip steel, need the smooth liquid of limit portion of cold-strip steel be purged, in purge, structure of nozzle and quality play very big effect to the control that purges smooth liquid, the nozzle product of at present domestic well-known producer of several families, all can not satisfy the quality requirement in the production, and the entry nozzle product price is too high, approximately be homemade nozzle 10-15 doubly, Lead Time will reach about half a year simultaneously, also influential to the normal production order that enterprise keeps, therefore press for design and make the new limit nozzle that blows, to satisfy the demand of producing.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can satisfy the wet requirement that limit portion purges when smooth of cold-strip steel fully, and the cheaper cold-strip steel of cost blows the limit nozzle.
The technical scheme that solves the problems of the technologies described above is:
A kind of cold-strip steel blows the limit nozzle, it comprises nozzle body, main airway, main mouthpiece and a plurality of secondary mouthpiece, nozzle body is a cylinder, main airway is on the axis of nozzle body, and main mouthpiece and secondary mouthpiece are connected the front end of main airway between the front end face of nozzle body, and main mouthpiece is on the axis of main airway, a plurality of secondary mouthpieces are looped around the uniform of main mouthpiece on every side, and the circumferential edges of their outward flange and main airway is tangent.
Above-mentioned cold-strip steel blows the limit nozzle, and the front portion of described nozzle body is conical, and the last plane of circular cone is the front end face of nozzle body, and its radius is the outer peripheral distance of nozzle body central axis to secondary mouthpiece, and the bottom surface of circular cone is the cylindrical circumference of nozzle body.
Above-mentioned cold-strip steel blows the limit nozzle, and the locknut of a circle to outer lug arranged on the middle part excircle of described nozzle body, and the periphery of locknut is a hexagon, on the bottom excircle of nozzle body the installation screw thread is arranged, and screw thread is installed and is blown the limit jet pipe to be complementary.
The utility model has adopted the design of major-minor mouthpiece, main mouthpiece will blow with the smooth liquid on the steel plate face, make smooth liquid produce high-speed motion, secondary mouthpiece can keep this smooth liquid high-speed motion thoroughly to blow off up to smooth liquid being with the steel plate face, the air-flow that secondary mouthpiece of while blows out reduces rapidly after going out to be with the steel plate face, has prevented splashing of smooth liquid.As long as the operating pressure of 0.4MPa that has the utility model just can realize wet requirement when smooth, reduce the operating pressure of air compressor machine, reduced compressed-air actuated air consumption, saved energy consumption, simultaneously the processing charges of nozzle has only tens yuans, has reduced many than the price of entry nozzle nearly 1,000 yuan.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Mark is as follows among the figure: nozzle body 1, main airway 2, main mouthpiece 3, secondary mouthpiece 4, locknut 5, installation screw thread 6.
The specific embodiment
The utility model comprises nozzle body 1, main airway 2, main mouthpiece 3 and a plurality of secondary mouthpiece 4.
Show among the figure that nozzle body 1 is a cylinder, the front portion of nozzle body 1 is conical, and the last plane of circular cone is the front end face of nozzle body 1, and the bottom surface of circular cone is nozzle body 1 a cylindrical circumference.
Show among the figure, main airway 2 is on the axis of nozzle body 1, main mouthpiece 3 and secondary mouthpiece 4 are connected the front end of main airway 2 between the front end face of nozzle body 1, main mouthpiece 3 is on the axis of main airway 2, a plurality of secondary mouthpieces 4 be looped around main mouthpiece 3 around, evenly lay, the circumferential edges of their outward flange and main airway 2 is tangent.The diameter of the taper seat of the front end face of nozzle body 1 equates with the circumference that the outward flange of a plurality of secondary mouthpieces 4 is connected to form.
Show among the figure that the locknut 5 of a circle to outer lug arranged on the middle part excircle of nozzle body 1, the periphery of locknut 5 is a hexagon, and the screw thread 6 of installation is arranged on the bottom excircle of nozzle body 1, screw thread 6 is installed and is blown the limit jet pipe to be complementary.During installation, operating personnel can be screwed in nozzle by locknut 5 and installation screw thread 6 with die nut or monkey wrench and blow on the jet pipe of limit.
The utility model is installed in the limit when using and blows on the jet pipe, operating pressure must not be lower than 0.4MPa, the approximate square in the cross section of its blow gas, main mouthpiece 3 will blow with the smooth liquid on the steel plate face, make smooth liquid produce high-speed motion, secondary mouthpiece 4 can keep this smooth liquid high-speed motion thoroughly to blow off up to smooth liquid being with the steel plate face, and the air-flow that secondary mouthpiece 4 of while blows out reduces to have prevented splashing of smooth liquid rapidly after going out with the steel plate face.
The beneficial effects of the utility model are: general nozzle is a mouthpiece mostly, does not then blow less than 0.4MPa such as air pressure and does; Then produce easily greater than 0.4MPa such as air pressure and to splash, air consumption is big simultaneously, and the operating pressure that requires of general entry nozzle also will could satisfy the wet purging requirement when smooth of planisher at 0.6-0.7MPa. And the utility model has reduced the operating pressure of air compressor machine as long as guarantee just can realize wetting requirement when smooth of the operating pressure of 0.4MPa, has reduced compressed-air actuated air consumption. Saved energy consumption, simultaneously because nozzle is the processing charges of autonomous Design only is tens yuans, reduced many than the price of entry nozzle nearly 1,000 yuan.
