Abstract
The utility model relates to a compound mosaic fireproof thermal insulating brick which comprises an alumina thermal insulating brick main body; the alumina thermal insulating brick main body is provided with a first main plane and a second main plane which are arranged oppositely; a Zr-Cr-Corundum fireproof face brick is embedded on the first main plane; and a thermal insulating material brick is formed on the second main plane. The compound mosaic fireproof thermal insulating brick combines the advantages of Zr-Cr-Corundum and an alumina material, is good in thermal stability and high temperature erosion resistance, has low possibility of flaking, and is anti-stripping, good in thermal insulation and energy conservation effects, long in service life, and suitable for serving as a fireproof material.
Description
Technical field
The utility model relates to a kind of refractory material, and more particularly, the utility model relates to a kind of combined tessera fireproof insulation brick.
Background technology
The thermal efficiency of western developed country industry activation furnace is generally 30%～40%; and the thermal efficiency of China's industry activation furnace on average only has 25%～35%; therefore improve the thermal efficiency of activation furnace, realize that energy-saving and emission-reduction are to alleviating Pressure on Energy, reducing production costs and link of protection all has great importance.The material that present activation furnace generally uses has sa sintered refractory and AZS refractory material.The sa refractory material effectively reduces load-bearing from heavy and light, but heat insulation effect is not good, and easily aliquation peels off, and pollutes glass metal, affects product quality, especially to high-quality product, endangers very large; The AZS refractory material is high temperature resistant, chemical resistance of concrete, anti-strip, long service life, but its shortcoming is heat radiation, is not incubated, and from great, increase load-bearing.
At present, heat-insulating heat-preserving material of the prior art in order to pursue larger heat insulation and preservation effect usually by increasing the porosity and the porosity of material, reaches and reduces the purpose that thermal conductivity realizes insulation.Yet the porosity and porosity must cause greatly again the strength ratio of material lower, and not only easily damage and lost affects the service life of material, and causes easily occurring impurity element in the product in the use, affects the quality of product.Usually by the dissimilar refractory material of exploitation, for example select siliceous, aluminium matter, magnesian in the prior art; Come simultaneously intensity and the heat-insulating property of balance material by various compounded formulas.Yet in the production process of reality, in order to reach certain intensity, have to again lose a part of porosity and the porosity, reduced so again heat insulation and preservation effect.
The utility model content
The above-mentioned technical problem that exists in order to solve prior art, the purpose of this utility model is to provide a kind of refractory, hollow brick, and refractory, hollow brick of the present utility model has excellent rigidity and intensity, simultaneously the good effect of heat insulation of material.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of combined tessera fireproof insulation brick, it is characterized in that comprising aluminium oxide insulating brick main body, described aluminium oxide insulating brick main body has relative primary principal plane and secondary principal plane, be embedded with the fire-resistant face brick of fused alumina zirconia on the described primary principal plane, be embedded with the heat-barrier material brick on the described secondary principal plane.
As preferably, the exterior surface area of the fire-resistant face brick of described fused alumina zirconia and the Area Ratio of described primary principal plane are 3/4-9/10.
As preferably, the exterior surface area of described heat-barrier material brick and the Area Ratio of described primary principal plane are 3/4-9/10.
As preferably, the thickness of the fire-resistant face brick of described fused alumina zirconia is 8-15mm.
As preferably, the thickness of described heat-barrier material brick is 10-18mm.
As preferably, the thickness of described aluminium oxide insulating brick main body is 60-120mm.
As preferably, the fire-resistant face brick of described fused alumina zirconia be shaped as rectangle, square, circle or oval.
As preferably, described heat-barrier material brick be shaped as rectangle, square, circle or oval.
As preferably, the fire-resistant face brick of described fused alumina zirconia is all identical with shape and the size of heat-barrier material brick.
Combined tessera fireproof insulation brick of the present utility model combines the advantage of fused alumina zirconia and alumina material, and heat endurance and high temperature resistant aggressivity are good, aliquation not, anti-strip, insulation, good energy-conserving effect, long service life, excellent combination property.
