Abstract
The utility model relates to an oxygen blowing spray head device of a large-ladle long nozzle. The oxygen blowing spray head device comprises a cover plate, a spray head, spray orifices, an oxygen tube and a cavity. The cover plate is a rigid high-temperature-resisting material, and an open hole is formed in the center of the cover plate. The spray head is shaped like a circular truncated cone and is made of refractory materials, and the spray orifices are formed in a small circular surface of the spray head; the spray orifices are annularly distributed in the small circular surface of the spray head; the oxygen tube is a rigid tube; the cavity is located in the center of the bottom surface of the spray head; the oxygen tube and the cover plate are fixedly connected in a welded mode. The spray orifices are formed in the spray orifice surface, so that oxygen is sprayed evenly, damage to the long nozzle is small, the purging effect is good, the service life of the long nozzle is prolonged, and the oxygen blowing spray head device has the advantages of being safe to use, even in oxygen blowing and free of damage to a long nozzle sized segment, guaranteeing the leakproofness of the long nozzle, and prolonging protective casting of a casting machine and the service life of the long nozzle.
Description
Technical field
The utility model belongs to the large bag long nozzle of metallurgy industry continuous casting oxygen blow head technical field, relates to a kind of use safety, and oxygen blast is even, large bag long nozzle oxygen blow head device that can scaling loss long nozzle the rim of a bowl.
Background technology
Along with the requirement of technological progress, protection cast has become a kind of general continuous casting pattern and has improved the means of steel quality.Large bag long nozzle protection cast is a kind of important means.In use very easily there is steel bonding, dry slag in water gap bowl portion in large bag long nozzle, if cleaning is unclean, affects continuous casting protection pouring, easily causes molten steel anthostele accident simultaneously.Large bag long nozzle oxygen blow head is for purging a kind of instrument of adhesive in the mouth of a river.Large bag long nozzle oxygen blow head used is to carry out with simple oxygen pipe at present.Its shortcoming has while being oxygen blast that sparks fly off molten steel, has larger potential safety hazard; Oxygen blast is uneven, and long water gap bowl part is had to scaling loss, has destroyed the sealing of long nozzle, affects conticaster protection cast and long nozzle life-span.
Utility model content
In order to overcome the above-mentioned shortcoming of prior art
,the utility model provides a kind of use safety, and oxygen blast is even, can scaling loss long nozzle the rim of a bowl, guaranteed the sealing of long nozzle, and extended conticaster protection cast and the large bag long nozzle oxygen blow head device in long nozzle life-span.
The utility model solves the technical scheme that its technical problem adopts: a kind of large bag long nozzle oxygen blow head device, comprise cover plate, shower nozzle, spray orifice, oxygen pipe, cavity, and cover plate is rigidity exotic material, there is a perforate at cover plate center; Shower nozzle is that the refractory material of truncated cone-shaped is made, and its little disc has spray orifice; Spray orifice circularizes the little disc that is distributed in shower nozzle; Oxygen pipe is rigidity pipe fitting; Cavity is positioned at shower nozzle bottom center; Oxygen pipe and cover plate are fixedly connected by welding.
The beneficial effects of the utility model are: owing to being provided with a plurality of spray orifices on spray orifice face, make oxygen ejection evenly; less to long nozzle infringement; purging effect is better; improve long nozzle service life; have use safety, oxygen blast is even, can scaling loss long nozzle the rim of a bowl; guarantee the sealing of long nozzle, extended conticaster protection cast and the feature in long nozzle life-span.
Accompanying drawing explanation
Fig. 1 is apparatus structure schematic diagram of the present utility model;
Fig. 2 is the utility model left view.
In figure: 1-cover plate, 2-shower nozzle, 3-spray orifice, 4-oxygen pipe, 5-cavity.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Referring to Fig. 1, a kind of large bag long nozzle oxygen blow head device, mainly consists of cover plate 1, shower nozzle 2, spray orifice 3, oxygen pipe 4, cavity 5 etc.Described cover plate 1 is rigidity exotic material, and there is a perforate at its center; Shower nozzle 2 is made for the refractory material of truncated cone-shaped, and its large disc is fixedly connected with cover plate 1, and little disc has spray orifice 3; Spray orifice 3 is for circularizing the little disc that is distributed in shower nozzle 1; Oxygen pipe 4 is rigidity pipe fitting, and the perforate on its one end and cover plate 1 is joined; Cavity is positioned at shower nozzle 2 bottom center; Oxygen pipe 4 one end and cover plate 1 are fixedly connected by welding, the external tracheae of the other end; Cover plate 1 is fixedly connected with shower nozzle 2 castings.
During actual use, oxygen enters oxygen-input tube 4 by tracheae 6, then enters cavity 5 by oxygen pipe 4, finally by spray orifice 3, evenly sprays.
The utility model makes oxygen ejection evenly owing to being provided with a plurality of spray orifices 3 on 3 of spray orifices; less to long nozzle infringement; purging effect is better; improve long nozzle service life; have use safety, oxygen blast is even, can scaling loss long nozzle the rim of a bowl; guarantee the sealing of long nozzle, extended conticaster protection cast and the feature in long nozzle life-span.
