Abstract
The utility model discloses a solve the problem that prior art existed, find a mouth of a river brick, reduce its replacement cost. Including mouth of a river brick body and the outflow hole of setting on the mouth of a river brick body, the outflow hole includes the last hole of upper segment and the lower hole of hypomere, goes up the round platform structure of hole for placing upside down, and lower hole is cylindrical structure, and the mouth of a river brick body includes that the brick is personally experienced sth. Part of the body and personally experience sth. Part of the body with last brick and to dismantle the lower brick body of being connected that going up the brick body and being cylindrical, lower brick is personally experienced sth. Part of the body to the round platform shape of placing upside down, is equipped with outside the mouth of a river brick body to be used for the fixed detachable metal -back of going up the brick body and the lower brick body of connection. Through implementing the utility model discloses can gain following useful technological effect: go up the brick body and can dismantle with the lower brick body, act as the brick integument and wash away when damaging, can change the brick body alone, reduce the replacement cost.
Description
Technical field
This utility model is related to refractory brick field and in particular to a kind of nozzle brick.
Background technology
It is embedded in the refractory material matter molten steel tap hole in the brick cup of ladle bottom.When not pouring into a mould, nozzle brick and stopper brick are in
Linear contact lay is it is ensured that not bleed-out.On nozzle brick, hole is arc surfaced, is easy to the resistance opened, close the mouth of a river and reduce MOLTEN STEEL FLOW, under
Section is straightway to stablize beam.Ladle capacity one timing, the internal diameter size of nozzle brick directly affects poring rate.According to many
Year using practice, at an upper portion thereof, and bottom is subject to degradation degree very little to the main portions being washed away by molten steel, the mouth of a river often
Brick top well damage, and the situation of bottom no damage substantially, in first prior art, when this situation, can only change whole
Individual nozzle brick, relatively costly.
Utility model content
The purpose of this utility model is to solve the problems of prior art, finds a kind of nozzle brick, reduces it more
Change this into.
In order to realize described purpose, a kind of nozzle brick of this utility model, including nozzle brick body and be arranged on nozzle brick this
Tap hole on body, described tap hole includes the upper hole of epimere and the lower opening of hypomere, and described upper hole is inverted frustum cone structure, institute
Stating lower opening is cylindrical structural, and described nozzle brick body includes brick body and the lower brick body being detachably connected with upper brick body, described
Upper brick body is cylinder, and described lower brick body is inverted truncated cone-shaped, and described nozzle brick outer body is provided with for being connected
Brick body and the Demountable metallic shell of lower brick body.
Preferably, described metal-back is barreled structure, and the bottom of metal-back is corresponding with lower brick body bottom shape, metal-back
Inside side walls shape corresponding with nozzle brick body sidewall shape.
Preferably, described metal-back is connected with upper brick body by bolt, and described metal shell side wall is provided with and passes through for bolt
Perforation, described upper brick body be provided with bolt cooperation screw.
Following Advantageous Effects can be obtained by implementing this utility model：Upper brick body and lower brick body are detachable, when upper
When brick body is washed damage, brick body can be individually replaced, reduce replacement cost.
Brief description
Fig. 1 is longitdinal cross-section diagram of the present utility model.
Specific embodiment
For the ease of the understanding of those skilled in the art, with reference to specific embodiment, this utility model is made further
Explanation：
As shown in figure 1, a kind of nozzle brick of this utility model, including nozzle brick body 1 be arranged on nozzle brick body 1
Tap hole 2, tap hole 2 includes the upper hole 21 of epimere and the lower opening 22 of hypomere, and upper hole 21 is inverted frustum cone structure, and lower opening 22 is
Cylindrical structural, nozzle brick body 1 includes brick body 11 and the lower brick body 12 being detachably connected with upper brick body 11, and upper brick body 11 is
Cylinder, lower brick body 12 is inverted truncated cone-shaped, and upper hole 21 is located in upper brick body 11, and nozzle brick outer body is provided with for connecting
The Demountable metallic shell 3 of brick body 11 and lower brick body 12 in fixation.Upper brick body 11 and lower brick body 12 are detachable, when upper brick body 11 quilt
During erosion failure, brick body 11 can be individually replaced, reduce replacement cost；Metal-back 3 serves upper brick body 11 He that is connected
The effect of lower brick body 12, serves the effect improving nozzle brick fire resistance again.
As preferred a kind of preferred structure of metal-back 3, metal-back 3 is barreled structure, the bottom of metal-back 3 and lower brick body
12 bottom shapes are corresponding, and the inside side walls shape of metal-back 3 is corresponding with nozzle brick body 1 sidewall shape, metal-back 3 and water
After mouth brick body connects, metal-back 3 inwall is close to nozzle brick body.Metal-back 3 is connected with upper brick body 11 by bolt 4, gold
Belong to shell 3 side wall and be provided with the perforation passing through for bolt 4, upper brick body 11 is provided with the screw with bolt 4 cooperation, will by bolt 4
Metal-back 3 is fixed with upper brick body, and fixing dismounting is more convenient, and perforation longitudinal section is horizontal T-shaped structure so as to shape and bolt
4 shapes are corresponding, and, after bolt 4 is connected with upper brick body 11, bolt 4 is embedded in perforation so that bolt 4 not shadow for metal-back 3
Ring installing and using of nozzle brick.
The foregoing is only specific embodiment of the utility model, but technical characteristic of the present utility model is not limited to
This, any those skilled in the art in field of the present utility model, all cover in this practicality newly by the change made or modification
Among the scope of the claims of type.
