Description
Technical field
The utility model relates to a kind of refractory material, and more particularly, the utility model relates to a kind of composite insulating brick with refractory coating.
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 composite insulating brick with refractory coating, it is characterized in that comprising fused alumina zirconia layer and aluminium oxide thermal isolation and heat storage layer, the inner surface of described fused alumina zirconia layer has projection or groove, and the inner surface of described aluminium oxide thermal isolation and heat storage layer has groove or the projection that is complementary with it, and is formed with the fireproof coating layer at the outer surface of composite insulating brick.
As preferably, the thickness of described fused alumina zirconia layer is 10-20mm.
As preferably, the thickness of described dope layer is 5-10mm.
As preferably, the thickness of described aluminium oxide thermal isolation and heat storage layer is 50-120mm.
As preferably, the Thickness Ratio of described fused alumina zirconia layer and aluminium oxide thermal isolation and heat storage layer is 1: 6-10.
As preferably, the Thickness Ratio of described fused alumina zirconia layer and aluminium oxide thermal isolation and heat storage layer is 1: 8.
As preferably, the inner surface of described fused alumina zirconia layer has projection, and the inner surface of described aluminium oxide thermal isolation and heat storage layer has the groove that is complementary with above-mentioned projection.
As preferably, the inner surface of described fused alumina zirconia layer has groove, and the inner surface of described aluminium 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 insulating brick heat endurance and high temperature resistant aggressivity with refractory coating of the present utility model is good, aliquation not, anti-strip, insulation, good energy-conserving effect, long service life, excellent combination property.
