Abstract
The invention provides a high-alumina composite refractory brick. The high-alumina composite refractory brick comprises a high-alumina refractory material framework and a light high-alumina refractory material filling layer, wherein the high-alumina refractory material framework is of a cuboid concave surface structure, zigzag crinkles are arranged on all four inner sides of the concave surface structure, the high-alumina refractory material filling layer is arranged in the concave portion of the concave surface structure and is tightly attached to the four sides of the concave surface structure, and the upper surface of the high-alumina refractory material framework is flush with the upper surface of the light high-alumina refractory material filling layer. The high-alumina composite refractory brick has the advantages that construction of a heat insulation lining is more convenient, construction intensity is reduced, the structure is simple, production is convenient, service life is long, and heat insulation performance is excellent.
Description
Technical field
The invention belongs to fire resisting material field, especially relate to the refractory brick of a kind of high alumina refractories and light weight alumina refractory material compound.
Background technology
In existing technology, the raw material heat-insulating property of refractory brick is poor, if need insulation, will increase building by laying bricks or stones of heat-insulation layer in addition, and cost and duration are increased.And present fire resistant heat preserving liner is normally made up of working lining and heat-insulation layer, by long-term use, working lining is different with high-temperature shrinkage rate with the density of heat-insulation layer, cause two-layer between produce space, the service life of fire resistant heat preserving liner is shortened.
Summary of the invention
The problem to be solved in the present invention is to provide one and has easy construction and excellent thermal insulation performance, the product of long service life, and the especially applicable clinkering zone of cement kiln, some position of glass furnace use as kiln lining.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of High-Alumina composite refractory brick comprises high alumina refractories skeleton and light weight alumina refractory material packed layer, described high alumina refractories skeleton is rectangle concave structure, the four sides, inner side of described concave structure is provided with zigzag ripple, described light weight alumina refractory material packed layer is filled in the sunk part of described concave structure, described high alumina refractories skeleton is concordant with the upper surface of described light weight alumina refractory material packed layer, the four sides of described light weight alumina refractory material packed layer and described concave structure fits tightly.
Described high alumina refractories skeleton is mullite-corundum matter skeleton.
Light weight alumina refractory material packed layer is the mixture of high alumina and bonding clay composition.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, this product can make building by laying bricks or stones of insulating lining convenient, reduces construction volume; There is structure simple, convenient for production, long service life, the advantages such as excellent thermal insulation performance.
Accompanying drawing explanation
Fig. 1 is High-Alumina composite refractory brick structural representation of the present invention.
Fig. 2 is High-Alumina composite refractory brick profile of the present invention.
In figure:
1, high alumina refractories skeleton, 2, light weight alumina refractory material packed layer.
Detailed description of the invention
As shown in Figure 2, the present invention's cuboid brick body that four limits have in the high alumina refractories skeleton 1 of zigzag ripple struction the light weight alumina refractory material packed layer 2 of filling and fit tightly inside skeleton to be combined into by rectangle concave structure and inside concave surface; And as shown in Figure 1, the high alumina refractories skeleton of this brick body is concordant with the upper surface of light weight alumina refractory material packed layer.
The shape of special high alumina refractories skeleton 1 structure and light weight alumina refractory material packed layer 2 ensure that the stability that bi-material combines and firmness; High alumina refractories skeleton 1 serves the effect of working lining, because it has good fire resistance, thermal structure intensity, slag resistance and resistance to heat shocks; Light weight alumina refractory material packed layer 2 serves the effect of heat-insulation layer, because it has good heat-insulating property and resistance to heat shocks.
Optimum embodiment is, the present invention is made into rectangle concave structure by use mullite-corundum fire resistant materials and inside concave surface, there is the skeleton of zigzag ripple struction on four limits, add water with high alumina and bonding clay compound again, make pulpous state pug, send in frothing machine and manufacture foam, mix, the mud making the light weight alumina refractory material of saturated foam is filled in the hollow part of skeleton, after abundant drying, after firing, make this composite refractory brick.
