Abstract
The utility model provides a steel ladle long nozzle for clean molten steel, which comprises a long nozzle main body, wherein an air blowing conduit made of fireproof materials with low thermal conductivity is arranged on the long nozzle main body; an argon blowing connection pipe is arranged on the air blowing conduit, the air blowing conduit is arranged above a slag line of the long nozzle main body, and the other end of the argon blowing connection pipe is connected with an argon blowing device. The provided steel ladle long nozzle has the function of purifying molten steel in a deepening way; with the adoption of the steel ladle long nozzle, the purifying effect for the molten steel in the continuous casting process can be improved and more excellent steel can be smelted.
Description
Technical field
The utility model relates to and a kind ofly is used for continuous casting protection and waters the steel ladle long nozzle, belongs to the metallurgical continuous casting equipment technical field.
Background technology
Continuous casting is between ladle and the tundish with ladle long nozzle, its from the ladle to the tundish steel flow and air separate, play preventing the molten steel stream that looses, the minimizing field trash enters and protects molten steel to avoid the effect of oxidation.
Along with the development of metallurgical technology and the aggravation of market competition, more and more higher to the quality requirement of steel, in order to satisfy this requirement, the ratio of protection casting is more and more higher.Therefore the use of long nozzle is also more and more.On the basis of protection molten steel secondary oxidation, for promoting the profound detergent power of long nozzle, designing and manufacturing this purifying of steel also is necessity very with long nozzle.
The utility model content
The purpose of this utility model is to solve above-mentioned technical problem, and a kind of purifying of steel ladle long nozzle is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of purifying of steel ladle long nozzle, comprise the long nozzle body, described long nozzle body is provided with the air blowing conduit of lower thermal conductivity refractory material, described air blowing conduit is provided with Argon and takes over, described air blowing conduit is arranged at the slag line top of long nozzle body, and the other end that described Argon is taken over is connected with the Argon device.
Further, above-described a kind of purifying of steel ladle long nozzle, the diameter of wherein said air blowing conduit is 5-10mm.
Further, above-described a kind of purifying of steel ladle long nozzle, the angle of wherein said air blowing conduit and long nozzle body top is not more than 90 degree.
The beneficial effects of the utility model are mainly reflected in: a kind of long nozzle that can play the effect of deep purifying molten steel is provided, the air blowing conduit is arranged on the body of the mouth of a river, the Argon of the external lower thermal conductivity refractory material of this conduit is taken over, casting process can be improved to the purification of molten steel effect, the high-quality steel can better be smelted.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: ladle long nozzle structural representation of the present utility model.
Wherein:
1 long nozzle body, 2 Argons are taken over 3 air blowing conduits
The specific embodiment
The utility model has disclosed a kind of purifying of steel ladle long nozzle, as shown in Figure 1, comprises long nozzle body 1, and described long nozzle body 1 is provided with the air blowing conduit 3 that adopts the lower thermal conductivity refractory material, and the diameter of air blowing conduit 3 is 5-10mm.Air blowing conduit 3 is provided with Argon and takes over 2, and air blowing conduit 3 is arranged at the slag line top of long nozzle body 1, and the other end of described Argon adapter 2 is connected with Argon device (meaning not shown in the figures).For guaranteeing better air inlet, air blowing conduit 3 is not more than 90 degree with the angle of long nozzle body 1 top.In addition, the diameter of air blowing conduit 3 can be according to different products, and different needs carry out different settings.
In the use, at first take over 2 and connect outside Argon device by Argon, and the purification of molten steel agent is introduced in the air blowing conduit 3 together by the Argon device, argon gas and purification of molten steel agent subsequently enters tundish with molten steel, and molten steel plays the effect of profound purify hot metal jointly under the double action of argon gas bubbles and purification of molten steel agent.
The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
