Abstract
The utility model relates to a fire resistance part field specifically is a novel aluminium carbon brick for hot metal bottle, including the base member, its characterized in that the base member is the tapering hollow cylinder of grow gradually, the base member comprises long and short two portion, and the tapering of length portion is greater than the tapering of weak point portion, and the base member lateral wall corresponds the level cutting from top to bottom and constitutes corresponding horizontal tangent plane, and corresponding spaced apart 3~8 recesses or the lug of being equipped with on the water -supply line and sewer side grain, recess and lug are joined in marriage and is connect, and the depth of groove is 13 of base member wall thickness. With aluminium carbon brick replacement high -alumina brick, the aluminium carbon brick has resistant the erosion, and excellent performances such as anti -strip and heat resistanceheat resistant shake are favorable to the work steady in a long -term of hot metal bottle.
Description
Technical field
The utility model relates to refractory part field, is specially a kind of Novel hot-metal bottle Al2O3C Bricks.
Background technology
Blast furnace is the capital equipment of ironmaking, and hot-metal bottle is as one of Primary containers holding molten iron, directly have influence on the normal operation of blast furnace the service life of hot-metal bottle, tradition high-alumina brick is the inner lining material that hot-metal bottle uses the earliest, but alumina firebrick corrodes obviously, drastically influence blast furnace normally to produce, be not suitable for using on existing hot-metal bottle, the utility model Al2O3C Bricks replaces high-alumina brick, Al2O3C Bricks has resistant to corrosion, the excellent properties such as anti-strip and anti-thermal shock, is conducive to the long-term stable operation of hot-metal bottle.
Summary of the invention
The purpose of this utility model is to corrode obviously for alumina firebrick pointed in background technology, has a strong impact on blast furnace and the shortcoming such as normally to produce, provide a kind of Novel hot-metal bottle Al2O3C Bricks that can solve foregoing problems.
For realizing the purpose of this utility model, there is provided following technical scheme: a kind of Novel hot-metal bottle Al2O3C Bricks, comprise matrix, it is characterized in that described matrix is the hollow cylinder that tapering becomes large gradually, described matrix is by length bipartition, and the tapering of long portion is greater than the tapering in short portion, the upper and lower corresponding horizontal resection of base side walls forms corresponding horizontal section, on upper and lower horizontal section, correspondence is spaced apart is provided with 3 ~ 8 grooves or projection, and groove and projection connect, and depth of groove is 1/3 of matrix wall thickness.
As preferably, long portion maximum diameter is less than the most path in short portion.
As preferably, described matrix surface and endoporus scribble heat insulating coat.
As preferably, long portion heat insulating coat thickness is 1/2 of short portion heat insulating coat thickness.
As preferably, heat insulating coat is acrylate/nano.
As preferably, the salic high grade bauxite of matrix, fused brown corundum and carborundum are fired and are formed.
The utility model beneficial effect: the utility model overcomes alumina firebrick and corrodes obviously, have a strong impact on blast furnace and the shortcoming such as normally to produce, provide a kind of Novel hot-metal bottle Al2O3C Bricks, its structure is hollow cylinder structure, anti-seismic performance is good, more fit time the design of horizontal section makes brick body pile up again firmly, the groove that upper and lower horizontal section intercouples and projection, improve bonding strength greatly.Al2O3C Bricks can by improving main material class, the adding kind and change production technology of optimization " additive ", and burn till without high temperature, only need 200 DEG C of low-temperature bakes to carry out the Al2O3C Bricks of the resistance to scouring of excellent, higher thermal shake stability, reduce cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
With preferred embodiment, the utility model is further described by reference to the accompanying drawings now.
Embodiment 1: a kind of Novel hot-metal bottle Al2O3C Bricks, comprise matrix 1, described matrix 1 is the hollow cylinder that tapering becomes large gradually, described matrix 1 is made up of long and short two portion (1.1,1.2), the tapering of long portion 1.1 is greater than the tapering in short portion 1.2, the upper and lower corresponding horizontal resection of matrix 1 sidewall forms corresponding horizontal section 1.3, on upper and lower horizontal section 1.3, correspondence is spaced apart is provided with 3 ~ 8 groove 1.3.1 or projection 1.3.2, groove 1.3.1 and projection 1.3.2 connects, and the groove 1.3.1 degree of depth is 1/3 of matrix 1 wall thickness.Long portion maximum diameter is less than the most path in short portion.Described matrix 1 surface and endoporus 1.4 scribble heat insulating coat 2.Long portion 1.1 heat insulating coat 2 thickness is 1/2 of short portion 1.2 heat insulating coat 2 thickness.Heat insulating coat 2 is acrylate/nano.The salic high grade bauxite of matrix 1, fused brown corundum and carborundum are fired and are formed.
The utility model is not limited to the hot-metal bottle involved by above-mentioned detailed description of the invention, those skilled in the art also can make multiple change accordingly, but to be anyly equal to the utility model or similar change all should be encompassed in the scope of the utility model claim.
