Abstract
The utility model relates to a submersed nozzle, in particular to a submersed nozzle which plays the role of good sealing function in molten steel continuous casting process. The ring groove air-sealing submersed nozzle comprises a nozzle body, wherein a bowl opening is formed at the upper part of the nozzle body, ring grooves are formed at the bowl opening along the inner wall, breathing holes are formed at the bowl opening, one ends of breathing holes are connected with ring grooves, and the other ends thereof are communicated with the external. In the submersed nozzle, ring grooves are formed on the inner wall of the bowl opening, breathing holes communicated with the external are formed on ring grooves, and the inert gas forms a lap of gas protective layer through filling the inert gas like argon in the breathing holes, so as to seal a gap between the nozzle and a tundish water discharge opening, therefore, the sealed object melting due to high temperature is avoided through the gas sealing, and the sealing effect is good.
Description
Technical field
The utility model relates to a kind of submersed nozzle, particularly a kind of submersed nozzle that plays the excellent sealing effect in the continuous casting of molten steel process.
Background technology
In the casting process of molten steel, molten steel enters tundish by ladle, is flow in the mouth of a river by tundish again; In the prior art, directly socket between the following mouth of a river of tundish and the submersed nozzle, and then seal with the cellucotton pad, but poor sealing like this, and the temperature of molten steel is too high, and the cellucotton pad that seals will soon be melted, and influences sealing more, seal the bad air contact molten steel that causes, influenced the quality of molten steel.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of submersed nozzle with excellent sealing.
The technical solution of the utility model: annular groove sealing gland submersed nozzle, comprise mouth of a river body, body top, the mouth of a river is the rim of a bowl, described the rim of a bowl has annular groove along inwall, also have passage on the rim of a bowl, passage one end is connected with annular groove, the passage other end and exterior.
As preferably, be provided with heat-resistant layer in described the rim of a bowl; Can improve the service life and the result of use at the mouth of a river.
As preferably, described heat-resistant layer adopts pyroceram fibre.
Submersed nozzle of the present utility model is offered annular groove at the rim of a bowl inwall; have passage on the annular groove with exterior; by inert gases such as feeding argon gas in passage; make inert gas in annular groove, form a circle gas shield layer and seal up the slit between the mouth of a river under submersed nozzle and the tundish; both need not worry the high temperature melt sealed object by air seal, and good sealing effect.
Description of drawings
Fig. 1 is a generalized section of the present utility model;
Fig. 2 is a three-dimensional cut-away illustration of the present utility model;
Schematic diagram when Fig. 3 is the mouth of a river of the present utility model work.
The specific embodiment
As shown in Figure 1, 2, annular groove sealing gland submersed nozzle comprises mouth of a river body 5, body 5 tops in the mouth of a river are the rims of a bowl 2, offer annular groove 3 along the rim of a bowl 2 inwalls one circle, also have passage 1 on the rim of a bowl 2, passage 1 one ends are connected with annular groove 3, passage 1 other end and exterior.Be provided with the heat-resistant layer 4 that adopts ceramic fibre in the rim of a bowl 2.Ceramic fibre is close to the rim of a bowl 2 inwall settings and is played sealing function, and molten steel flows out downwards from mouth of a river body 5 after the rim of a bowl enters the mouth of a river.
As shown in Figure 3; when carrying out continuous casting of molten steel; molten steel enters tundish 7 from ladle 6; molten steel flows into the rim of a bowl 2 at the mouth of a river by the following mouth of a river 9 of tundish 7; fill in breather pipe in the passage 1; in passage 1, feed inert gases such as argon gas by aerating device 8; make inert gas in annular groove 3, form a circle gas shield layer and seal up the slit between the mouth of a river under the rim of a bowl at the mouth of a river and the tundish; prevent that extraneous air from entering the quality that influences molten steel in the mouth of a river; both need not worry the high temperature melt sealed object by air seal, and good sealing effect.
Claims (3)
