Abstract
The utility model relates to a brick is inlayed to protection type heat, it includes the brick material, the refractory fiber felt is covered in the subsides of brick material outer wall to fill the siliceous resistant material of high alumina matter or carbonization, suppress outer high alumina or the carborundum brick base that covers the refractory fiber felt into, make brick is inlayed to protection type heat through firing, the thickness of refractory fiber felt is 5~8mm, and the refractory fiber felt ring (collar is around the cladding at brick material surface. The utility model discloses a brick is inlayed to protection type heat manufacturing process reliable and simple inlays the refractory fiber felt of brick surface through the cladding in heat, can keep apart and block high temperature iron liquid to the harm of the brick body, and the buffering is made a concession indisputable liquid solidification shrinkage and to the destruction of the brick body, has been avoided heat to inlay the brick and caused the damage and crack the brick body, has higher practical value and economic implications.
Description
Technical field
The utility model belongs to metallurgical casting industry, and particularly a kind of heat of the protection type for metallurgical furnace cooling stave edge brick, is the part of resistance to material.
Background technology
Heat edge brick cooling stave is as the important water-cooling section of blast furnace, and the quality of its heat edge brick decides the life-span of cooling stave and blast-furnace body.
Heat edge brick cooling stave is fixed on by refractory brick in cooling stave sand mold die cavity, and then pour into high temperature liquid iron, after iron liquid cooled and solidified, refractory brick is embedded in cooling stave, makes heat edge brick cooling stave.Be characterized in that cooling stave and heat are inlayed between brick to combine closely, edge brick firm and durable.
But due in cooling stave casting process, refractory brick is directly subject to high temperature iron liquid and corrodes and thermal radiation is impacted, and after unpacking, brick body appearance tiny crack in various degree or localized delamination, had a strong impact on edge brick quality and work-ing life.
In view of this, person skilled in art is devoted to the protection type heat edge brick researching and developing a kind of improvement.
Summary of the invention
Task of the present utility model is to provide a kind of protection type heat edge brick of improvement, it solve the problem existing for above-mentioned prior art, wherein adopt High-Alumina or the resistance to material of silicon carbide and fire-retardent fiber felt-rug, high temperature iron liquid is blocked to the infringement of brick body to isolate, buffering makes a concession iron liquid solidification shrinkage to the destruction of brick body, avoids heat edge brick and causes damage to brick body and crack.
Technical solution of the present utility model is as follows:
A kind of protection type heat edge brick, it comprises brick material, and described brick material outer wall pastes fire-retardent fiber felt-rug, and filling High-Alumina or the resistance to material of silicon carbide, is pressed into outer high alumina or the silicon carbide adobe of covering fire-retardent fiber felt-rug, fired and make protection type heat edge brick;
The thickness of described fire-retardent fiber felt-rug is 5 ~ 8mm, and fire-retardent fiber felt-rug is around being coated on brick material outside surface.
Described protection type heat edge brick is embedded in cooling stave and forms heat edge brick cooling stave.
Protection type heat edge brick of the present utility model pastes fire-retardent fiber felt-rug at brick outer wall, and filling High-Alumina or the resistance to material of silicon carbide, be pressed into outer high alumina or the silicon carbide adobe of covering fire-retardent fiber felt-rug, then enters klining and become protection type heat edge brick.
Protection type Re Xiang brick manufacturing process of the present utility model is simple, by being coated on the fire-retardent fiber felt-rug of heat edge brick outside surface, can isolate and block high temperature iron liquid to the infringement of brick body, buffering makes a concession iron liquid solidification shrinkage to the destruction of brick body, avoid heat edge brick cause damage to brick body and crack, there is higher practical value and economic implications.
The range of application of protection type heat edge brick of the present utility model is heat edge brick cooling stave, is applicable to sand mold manufacture, belongs to metallurgy industry.

Fig. 2 is the structural representation that the heat of protection type shown in Fig. 1 edge brick is embedded in cooling stave.
Reference numeral:
1 is cooling stave, and 2 is heat edge brick, and 3 is fire-retardent fiber felt-rug.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Referring to Fig. 1, the utility model provides a kind of protection type heat edge brick, pastes fire-retardent fiber felt-rug 3, and filling High-Alumina or the resistance to material of silicon carbide, be pressed into outer high alumina or the silicon carbide adobe of covering fire-retardent fiber felt-rug at brick material outer wall, fired and make protection type heat edge brick 2.
As shown in fig. 1, fire-retardent fiber felt-rug 2 is around being coated on brick material outside surface.The thickness of fire-retardent fiber felt-rug 2 is 5 ~ 8mm.
Referring to Fig. 2, protection type heat edge brick 2 is embedded in cooling stave and forms heat edge brick cooling stave.
Protection type Re Xiang brick manufacturing process of the present utility model is simple, by being coated on the fire-retardent fiber felt-rug of heat edge brick outside surface, can isolate and block high temperature iron liquid to the infringement of brick body, buffering makes a concession iron liquid solidification shrinkage to the destruction of brick body, avoid heat edge brick cause damage to brick body and crack, there is higher practical value and economic implications.
Certainly, those skilled in the art in the art will be appreciated that, above-described embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, the change, modification etc. of above-described embodiment all will be dropped in the scope of the utility model claim.
