Description
Technical Field
The utility model relates to a ladle nozzle, concretely relates to compound ladle nozzle belongs to carbonaceous refractory material application technical field.
Background
The ladle slide gate nozzle is an important system for controlling the flow of molten steel in a ladle, if a steel penetrating accident occurs in the using process of the system, the system can cause serious production accidents such as casting machine breaking, continuous casting machine equipment burning and the like, the stable and smooth operation of production is restricted, and the personal safety and the equipment safety are seriously threatened. With the further acceleration of the steelmaking rhythm, higher requirements are provided for accelerating the turnover of the ladle and reducing production accidents, and the precondition for ensuring the safe operation of the sliding nozzle is that. The times of steel leakage of the sliding nozzle of the small ladle are more, the steel leakage accident of the sliding nozzle is reduced or stopped, and the method has very important significance for steel plants with faster and faster production pace.
The ladle slide gate valve generally consists of a drive unit, a mechanical part and a refractory material part. At present, in order to improve the quality of a ladle nozzle and reduce the times of replacing the nozzle, the structure of the existing ladle nozzle mostly adopts a high-grade aluminum-carbon nozzle with an integral structure, and the existing ladle nozzle is high in price, poor in disassembly property and higher in updating cost after being damaged.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the composite ladle nozzle has the advantages that the defects in the prior art are overcome, the composite ladle nozzle is provided, the whole nozzle is changed into the composite nozzle through the composition of the inner layer structure and the outer layer structure, the product cost is reduced, the product cost performance is improved, and the service life is prolonged under the condition that the service performance of a product is not reduced.
The utility model discloses a technical scheme who solves technical problem and take is: the utility model provides a compound ladle mouth of a river, includes the mouth of a river body, the mouth of a river body is the siphonozooid, and it is inside including upper segment flare opening, interlude connecting pipe and the trapezoidal flaring of hypomere, the outer fringe middle part of mouth of a river body is provided with inlays the groove, it has the inlay layer to inlay the groove closely to cooperate, the outer fringe on inlay layer with the outer fringe smooth connection of mouth of a river body.
The distance between the upper end of the embedding layer and the upper end of the water gap body is 50mm, and the distance between the lower end of the embedding layer and the lower end of the water gap body is 50 mm.
The nozzle body is made of corundum aluminum carbon, and the embedding layer is made of high-aluminum carbon.
The utility model has the advantages that: the utility model discloses an inner and outer layer composite construction replaces overall structure, is favorable to the assembly and the change at the mouth of a river, and the inner and outer layer uses different materials, is guaranteeing under the condition that product performance does not reduce, has reduced product cost, improves and produces the product nature price ratio.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be further explained and explained with reference to the drawings and the embodiments:
referring to fig. 1, there is shown 1-nozzle body, 2-inlay.
Example (b): the utility model provides a compound ladle mouth of a river, includes mouth of a river body 1, and mouth of a river body 1 is the siphonozooid, and it is inside including upper segment infundibulum mouth, interlude connecting pipe and the trapezoidal flaring of hypomere, and the outer fringe middle part of mouth of a river body 1 is provided with inlays the groove, inlays that the groove closely cooperates and has inlays layer 2, inlays the outer fringe on layer 2 and the outer fringe smooth connection of mouth of a river body 1.
The distance between the upper end of the embedding layer 2 and the upper end of the water gap body 1 is 50mm, and the distance between the lower end of the embedding layer 2 and the lower end of the water gap body 1 is 50 mm.
The nozzle body 1 is made of corundum aluminum carbon material, and the embedding layer 2 is made of high-aluminum carbon material.
The utility model discloses an inner and outer layer composite construction replaces overall structure, is favorable to the assembly and the change at the mouth of a river, and the inner and outer layer uses different materials, is guaranteeing under the condition that product performance does not reduce, has reduced product cost, improves and produces the product nature price ratio.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments still fall within the scope of the technical solution of the present invention.
