Abstract
The utility model relates to a composite fire-proof insulating brick which comprises a fused zirconia alumina fire-proof layer and an aluminum oxide heat-insulating thermal storage layer, wherein the ratio between of the thicknesses of the fused zirconia alumina fire-proof layer and the aluminum oxide heat-insulating thermal storage layer is 1 : (5 to 12); protrusions or grooves are arranged on the inner surface of the fused zirconia alumina fire-proof layer; and grooves or protrusions matched with the protrusions or the grooves in the inner surface of the fused zirconia alumina fire-proof layer are arranged on the inner surface of the aluminum oxide heat-insulating thermal storage layer. Combined with the advantages of fused zirconia alumina and aluminum oxide, the composite fire-proof insulating brick is good in heat stability and high-temperature erosion resistance, can not peel, and is peeling resistant, heat insulating, good in energy saving effect, long in service life, and excellent in comprehensive performance, thereby being suitable to be used as a fire-resisting material.
Description
Technical field
The utility model relates to a kind of refractory materials, and more particularly, the utility model relates to a kind of composite fire insulating brick.
Background technology
The thermo-efficiency of western developed country industry activation furnace is generally 30%~40%; and the thermo-efficiency of China's industry activation furnace on average only has 25%~35%; therefore improve the thermo-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 sal sintered refractory and electric fused zirconium corundum refractory materials.The sal refractory materials 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 quality product, especially to high-quality product, endangers very large; The electric fused zirconium corundum refractory materials is high temperature resistant, chemical resistance of concrete, antistripping, 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 void content and the porosity of material, reaches and reduces the purpose that thermal conductivity realizes insulation.Yet void content and porosity must cause greatly again the strength ratio of material lower, and not only easily damage and lost affects the work-ing 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 materials 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 void content, 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 composite fire insulating brick is characterized in that comprising zircon corundum flame retardant coating and aluminum oxide thermal isolation and heat storage layer, and the Thickness Ratio of zircon corundum flame retardant coating and aluminum oxide thermal isolation and heat storage layer is 1: 5-12; And the internal surface of described zircon corundum flame retardant coating has projection or groove, and the internal surface of described aluminum oxide thermal isolation and heat storage layer has groove or the projection that is complementary with it.
As preferably, the thickness of described zircon corundum flame retardant coating is 10-20mm.
As preferably, the thickness of described aluminum oxide thermal isolation and heat storage layer is 50-200mm.
As preferably, the Thickness Ratio of described zircon corundum flame retardant coating and aluminum oxide thermal isolation and heat storage layer is 1: 7-10.
As preferably, the Thickness Ratio of described zircon corundum flame retardant coating and aluminum oxide thermal isolation and heat storage layer is 1: 8.
As preferably, the internal surface of described zircon corundum flame retardant coating has projection, and the internal surface of described aluminum oxide thermal isolation and heat storage layer has the groove that is complementary with above-mentioned projection.
As preferably, the internal surface of described zircon corundum flame retardant coating has groove, and the internal surface of described aluminum oxide thermal isolation and heat storage layer has the projection that is complementary with above-mentioned projection.
As preferably, described projection be shaped as cylindrical or cuboid.
Composite fire insulating brick of the present utility model combines the advantage of zircon corundum and alumina material, and thermostability and high temperature resistant aggressiveness are good, aliquation not, antistripping, insulation, good energy-conserving effect, long service life, excellent combination property.
