Abstract
The utility model relates to a steelmaking technical field, in particular to well mouth of a river among dip-coating anti-oxidation coating, well mouth of a river comprises bowl mouth, transition material, body and inside lining, the bowl mouth is equipped with anti-oxidation anti-adhesion coating specially, bowl mouth and body are connected through transition material, the utility model discloses can avoid the oxide to adhere to in bowl mouth inboard at the anti-oxidation anti-adhesion coating that bowl mouth specially was equipped with, cause the bowl mouth to block up and the accident that causes stops the emergence of watering the accident, the life of well mouth of a river among the extension.
Description
Technical Field
The utility model relates to a molten steel continuous casting technical field, concretely relates to well package mouth of a river of dip-coating anti oxidation coating.
Background
The tundish nozzle is an intermediate link of a steelmaking production flow and is a joint point which is changed from intermittent operation to continuous operation. The tundish nozzle is used as a refractory material container, and the poured molten steel is mainly distributed into each crystallizer through the tundish nozzle. The tundish nozzle is an important link for improving the quality and the yield of steel, and the function of the tundish nozzle is not negligible no matter the continuous casting operation is smoothly carried out or the quality of molten steel is ensured to meet the requirement.
The tundish nozzle is positioned between a ladle of the continuous casting machine and the crystallizer and receives molten steel poured from the ladle. When molten steel passes through the tundish nozzle, secondary oxidation can be caused, oxidation impurities can exist in the molten steel, the oxidation impurities can be adsorbed on the inner wall to block molten steel casting, and the tundish nozzle can be blocked when the molten steel is serious, so that casting stop accidents are caused.
The utility model discloses lie in overcoming prior art not enough, provide one kind and avoid the mouth of a river to block up and take place to stop well package mouth of a river of watering accident.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a well mouth of a river of china of dip-coating anti-oxidation coating solves among the prior art oxidation impurity and can adsorb on well mouth of a river bowl mouth inner wall of china, causes to block up and stops this technical problem of accident of watering. The tundish nozzle can avoid the nozzle blockage to cause the casting stop accident.
In order to realize the purpose, the utility model provides a well mouth of a river of zhong of dip-coating anti-oxidation coating, including bowl mouth, transition material, body and inside lining, the bowl mouth is equipped with anti-oxidation anti-adhesion coating specially.
Further, the height of the anti-oxidation anti-adhesion coating accounts for 90% -95% of the height of the whole bowl mouth.
Further, the thickness of the anti-oxidation anti-adhesion coating is 2-4 mm.
Further, the diameter of the bottom opening of the bowl mouth is 1/4-2/5 of the diameter of the top opening.
Compared with the prior art, the beneficial effects of the utility model are that: the anti-oxidation anti-adhesion coating specially arranged on the bowl mouth can prevent the oxide from being attached to the inner side of the bowl mouth to cause the accidental stop of pouring due to the blockage of the bowl mouth, and prolong the service life of the tundish nozzle. And the diameter of the top opening of the bowl opening is larger than that of the bottom opening, so that the hot flushing force of molten steel on the tundish nozzle is reduced, and the service life of the tundish nozzle is further prolonged.
Drawings
Fig. 1 is a schematic structural view of a tundish nozzle for dip-coating an anti-oxidation coating of the present invention;
in the figure: 1. a bowl mouth; 2. transition materials; 3. a body; 4. a liner; 5. an anti-oxidation anti-adhesion coating.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1, the present invention provides an embodiment: a tundish nozzle dip-coated with an anti-oxidation coating comprises a bowl opening 1, a transition material 2, a body 3 and a lining 4, wherein the bowl opening is specially provided with the anti-oxidation anti-adhesion coating 5.
Further, the height of the anti-oxidation anti-adhesion coating 5 accounts for 90% -95% of the height of the whole bowl mouth.
Further, the thickness of the anti-oxidation anti-adhesion coating 5 is 2-4 mm.
Further, the diameter of the bottom opening of the bowl mouth is 1/4-2/5 of the diameter of the top opening.
The utility model has the advantages that: the anti-oxidation anti-adhesion coating specially arranged on the bowl mouth can prevent the oxide from being attached to the inner side of the bowl mouth to cause the accidental stop of pouring due to the blockage of the bowl mouth, and prolong the service life of the tundish nozzle. And the diameter of the top opening of the bowl opening is larger than that of the bottom opening, so that the hot flushing force of molten steel on the tundish nozzle is reduced, and the service life of the tundish nozzle is further prolonged.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
