Background

The alumina hollow ball brick is prepared by using alumina hollow balls and alumina powder as main raw materials and combining with other binding agents and firing at a high temperature of 1750 ℃, belongs to one of energy-saving and heat-insulating materials of ultra-high temperature materials, is a novel high-temperature heat-insulating material, is prepared by melting and blowing industrial alumina in an electric furnace, and has a crystal form of a-Al2O3 microcrystal. The alumina hollow ball is used as a main body, can be made into products of various shapes, has the highest use temperature of 1800 ℃, has high mechanical strength which is several times of that of common light products, has the volume density which is only one half of that of corundum products, and is widely applied to high-temperature and ultrahigh-temperature kilns such as petrochemical industry gasification furnaces, carbon black industry reaction furnaces, metallurgical industry induction furnaces and the like.

Present traditional alumina hollow ball is able to bear or endure firebrick splices the department and generally is planar at the in-process that uses, connects between the adjacent fragment of brick and produces the gap easily, long-time back causes not hard up easily, then collapses heavily, endangers the staff, and resistant firebrick is in the high temperature for a long time, hot gas gets into resistant firebrick's inside, produces expend with heat and contract with cold's principle, damages resistant firebrick's inner structure, causes resistant firebrick's breaking, produces the wasting of resources, consequently needs an alumina hollow ball to be able to bear or endure firebrick.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the joint is not stable enough in the prior art, and the high temperature easily causes the defect of damage to the internal structure, and provides an alumina hollow sphere refractory brick.

In order to realize the purpose, the utility model adopts the following technical scheme:

the utility model provides an alumina hollow ball refractory brick, includes the brick body, the externally mounted of the brick body has concatenation body A, the externally mounted of the brick body has concatenation body B, concatenation groove A has been seted up to the inside of the brick body, concatenation groove B has been seted up to the inside of the brick body, the internally mounted of the brick body has the set-square, a plurality of circular recesses have been seted up to the inside of set-square, the externally mounted of set-square has the cross rod, through setting up concatenation groove A and concatenation body A, concatenation body B and concatenation groove B will splice body A and put into to the concatenation groove A of adjacent resistant firebrick, will splice body B card simultaneously and go into the concatenation groove B of adjacent resistant firebrick, both combine to this to resistant firebrick junction reciprocal anchorage, prevent resistant firebrick because the junction is stable inadequately and cause in long-term work process from collapsing.

The above technical solution further comprises: the inside of set square has seted up the cavity, the externally mounted of set square has a plurality of blast pipes.

The inside of the brick body is provided with a heat insulation layer.

The size of the opening of the splicing groove A is matched with that of the splicing body A.

The size of the opening of the splicing groove B is matched with that of the splicing body A.

The blast pipe is kept away from the one end of set-square runs through to the outside of the brick body discharges remaining high-temperature gas to the outside of the brick body, prevents that high-temperature gas from influencing the structure of the brick body in the brick body, causing the fracture of the brick body.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses in, through setting up splice groove A and concatenation body A, splice groove A sets up respectively in the both sides of the brick body with concatenation body A, when needs pile up resistant firebrick, will splice body A and put into to the splice groove A of adjacent resistant firebrick, will splice body B card simultaneously and go into adjacent resistant firebrick splice groove B, both combine.

2. The utility model discloses in, when the internal portion of brick gets into high-temperature gas, stop most high-temperature gas at first by the blast pipe, during remaining high-temperature gas gets into the inside of the brick body, through a plurality of circular recesses that set up inside the set-square, introduce high-temperature gas in the inside cavity of set-square, then discharge high-temperature gas through the blast pipe, avoid high-temperature gas to damage inner structure in the brick body, cause the rupture of resistant firebrick, produce the wasting of resources.
