Abstract
The utility model relates to a composite refractory brick which comprises a zirconia alumina bottom layer, an aluminum oxide middle layer and a zirconia alumina surface layer. The composite refractory brick is fine in heat stability and high-temperature erosion resistance, free of flaking, anti-stripping, fine in heat insulation and energy saving effects, long in service life and applicable to serving as a refractory heat insulation material for various heating furnaces.
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 refractory 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 easily causes 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 composite refractory brick, and composite refractory 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 refractory brick is characterized in that comprising zircon corundum bottom, aluminum oxide middle layer and zircon corundum surface layer.
As preferably, the thickness of described zircon corundum bottom is 15-25mm.
As preferably, the thickness of described zircon corundum surface layer is 15-25mm.
As preferably, the Thickness Ratio of the thickness of described zircon corundum bottom and zircon corundum surface layer is 0.8-1.2.
As preferably, the Thickness Ratio of the thickness of described zircon corundum bottom and zircon corundum surface layer is 1.
As preferably, the thickness in described aluminum oxide middle layer is 35-70mm.
As preferably, the upper surface of described zircon corundum bottom has projection, and the lower surface in described aluminum oxide middle layer has the groove that is complementary with above-mentioned projection.
As preferably, the upper surface of described zircon corundum bottom has groove, and the lower surface in described aluminum oxide middle layer has the projection that is complementary with above-mentioned groove.
Composite refractory 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.
