Abstract
The utility model relates to a converter bottom-blowing device, comprising an air brick arranged at the bottom of the converter, an air brick tail pipe and a vent pipe, wherein the upper end of the air brick tail pipe is connected with the lower end of the air brick; the converter bottom-blowing device further comprises an air inlet hole arranged at the bottom of a permanent layer of the converter bottom; the vent pipe is transversely arranged in the permanent layer of the converter bottom, one end of the vent pipe is connected with the lower end of the air brick tail pipe in the permanent layer of the converter bottom, and the other end is bent and extends out of the converter through the air inlet hole. The converter bottom-blowing device has the following advantages: as the vent pipe is transversely arranged in the permanent layer of the converter bottom and is connected with the air brick tail pipe in the permanent layer of the converter bottom, a labyrinth passage structure of molten steel is formed at the converter bottom; and when molten steel leaks, the occurrence of leakage of the molten steel can be prevented as molten steel can be cooled before bleeding out.
Description
Technical field
The utility model relates to converter, particularly converter bottom blowing device.
Background technology
On modernized mammoth conveter, top bottom compound blowing technology is used comparatively ripe, become the standard configuration of modernized converter substantially, and bottom blowing system need be connected inner gas permeable brick with outside supply air line.
As shown in Figure 1; present method of attachment mainly is directly to pass method; its gas permeable brick tail pipe 3 directly passes the outer back of stove and links to each other with the outer permeability cell 7 of stove; be that furnace bottom air inlet port 6 is under gas permeable brick 1; gas permeable brick tail pipe 3 usefulness protective casings 8 entangle; fill with ramming mass 9 on every side, this kind method is applicable to that furnace bottom adopts the converter of cross building method.For the converter of using annular building method, need the higher precision of building by laying bricks or stones accurate to guarantee contraposition.
The method that directly passes take place in converter bottom the slit when oozing steel owing to there is not the protection of furnace bottom permanent layer, make molten steel very easily from the box hat the bottom blowing hole directly ooze out, enlarged and oozed the steel passage and cause bleed-out.
The utility model content
Technical problem to be solved in the utility model is: a kind of converter bottom blowing device is provided, and this device can prevent that invar water from from the gas permeable brick seepage bleed-out taking place.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of converter bottom blowing device, it comprises gas permeable brick, gas permeable brick tail pipe and the permeability cell that is arranged on furnace bottom; The upper end of gas permeable brick tail pipe is connected with the lower end of gas permeable brick; Converter bottom blowing device also comprises the air inlet port that is arranged on furnace bottom permanent layer bottom; Permeability cell is lateral arrangement in the furnace bottom permanent layer, and an end of permeability cell is connected with the lower end of gas permeable brick tail pipe in the furnace bottom permanent layer, stretches out outside the stove by air inlet port after the other end bending of permeability cell.
In the such scheme, connect by the elbow web member between gas permeable brick tail pipe and the permeability cell.
In the such scheme, the gas permeable brick tail pipe is a curved tube.
In the such scheme, gas permeable brick tail pipe and permeability cell are high temperature resistant pipeline.
Advantage of the present utility model is: because permeability cell lateral arrangement in the furnace bottom permanent layer, and in the furnace bottom permanent layer, be connected with the gas permeable brick tail pipe, formed the labyrinth channel structure of molten steel at furnace bottom, during the molten steel seepage, because molten steel can cool off before oozing out, and has avoided the generation of bleed-out.

Among the figure: 1-gas permeable brick, 2-furnace bottom permanent layer, 3-gas permeable brick tail pipe, 4-elbow web member, 5-furnace bottom box hat, 6-air inlet port, 7-permeability cell, 8-protective casing, 9-ramming mass.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
The utility model converter bottom blowing device embodiment as shown in Figure 2, it comprises gas permeable brick 1, gas permeable brick tail pipe 3, permeability cell 7 that is arranged on furnace bottom and the air inlet port 6 that is arranged on furnace bottom permanent layer 2 bottoms, and air inlet port 6 is opened on the furnace bottom box hat 5 of furnace bottom permanent layer 2 bottoms; The upper end of gas permeable brick tail pipe 3 is connected with the lower end of gas permeable brick 1; Permeability cell 7 is lateral arrangement in furnace bottom permanent layer 2, and an end of permeability cell 7 is connected with the lower end of gas permeable brick tail pipe 3 by elbow web member 4 (as shown in Figure 3) in furnace bottom permanent layer 2, stretches out outside the stove by air inlet port 6 after the other end bending of permeability cell 7.
Gas permeable brick tail pipe 3 also is a curved tube.Gas permeable brick tail pipe 3 and permeability cell 7 are high temperature resistant pipeline.
Principle of work of the present utility model is: bottom blown gas enters from permeability cell 7, arrives gas permeable brick 1 by gas permeable brick tail pipe 3, carries out bottom blowing by 1 pair of molten steel of gas permeable brick and stirs.In the work, if the molten steel seepage takes place, then molten steel can flow along gas permeable brick tail pipe 3 and enter permeability cell 7 through web member, because ventilative tail pipe is crooked, so the flow process of molten steel increases greatly, and the junction of gas permeable brick tail pipe 3 and permeability cell 7 is embedded in the furnace bottom permanent layer 2, molten steel is cooling gradually in flowing, avoid the further expansion of seepage, and then avoided the generation of bleed-out, guaranteed the security of producing.
