Abstract
The utility model relates to a compound fire-resistant insulating brick with an inside liner. The compound fire-resistant insulating brick comprises an aluminum oxide insulating brick main body. A zirconium corundum fire-resistant face brick is embedded on a first main plane of the aluminum oxide insulating brick main body and extends from the first main plane to form a protruded plane, and the silicon carbide inside liner is coated on an un-embedded part of the first main plane. The compound fire-resistant insulating brick with an inside liner is good in heat insulation effect, heat stability and high-temperature corrosion resistance, free of flaking, resistant to stripping, good in heat-insulating and energy-saving effects, long in service life and suitable for serving as a fire-resistant 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 with air retaining wall.
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 composite fire insulating brick with air retaining wall, composite fire insulating brick with air retaining wall 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 with air retaining wall, it is characterized in that comprising aluminum oxide insulating brick main body, be inlaid with zirconia-corundum refractory brick on the primary principal plane of described aluminum oxide insulating brick main body, and described zirconia-corundum refractory brick extends to form from described primary principal plane and protrudes the plane, and the part of not inlaying on the described primary principal plane forms and is coated with the silicon carbide lining layer.
As preferably, the thickness of described silicon carbide lining layer is 3-5mm.
As preferably, the thickness of described zirconia-corundum refractory brick is 12-18mm.
As preferably, the thickness of described aluminum oxide insulating brick main body is 72-108mm.
As preferably, the Thickness Ratio of described zirconia-corundum refractory brick and aluminum oxide insulating brick main body is 1: 6.
As preferably, the surface of described zirconia-corundum refractory brick is rectangle, square, circle or oval.
As preferably, the surface of described zirconia-corundum refractory brick is square or circular.
As preferably, described zirconia-corundum refractory brick is at least 1.
As preferably, described zirconia-corundum refractory brick is more than 2 or 2.
Composite fire insulating brick with air retaining wall of the present utility model has good heat insulating effect, and thermostability and high temperature resistant aggressiveness are good, aliquation not, antistripping, insulation, good energy-conserving effect, long service life.
