Abstract
The utility model relates to a compound fire-resistant insulating thermal insulation brick with an inside liner. The compound fire-resistant insulating thermal insulation brick comprises an aluminum oxide thermal insulation brick main body, a zirconia-corundum fire-resistant brick is embedded on one surface of the aluminum oxide thermal insulation brick main body, and furthermore, the silicon carbide inside liner is formed on the surface of the aluminum oxide thermal insulation brick main body. The compound fire-resistant insulating thermal insulation brick with the inside liner has good thermal insulation effect and is good in thermal stability and high temperature corrosion resistance, free of flaking, resistant to stripping, good in thermal insulation 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 material, and more particularly, the utility model relates to a kind of composite fire insulating brick with inner liner.
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 composite fire insulating brick with inner liner, composite fire insulating brick with inner liner 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 inner liner, it is characterized in that comprising aluminium oxide insulating brick main body, be inlaid with zirconia-corundum refractory brick on the surface of described aluminium oxide insulating brick main body, and further, be formed with the silicon carbide lining layer on the described surface.
As preferably, the thickness of described silicon carbide lining layer is 3-5mm.
As preferably, the thickness of described zirconia-corundum refractory brick is 10-18mm.
As preferably, the thickness of described aluminium oxide insulating brick main body is 75-150mm.
As preferably, the Thickness Ratio of described zirconia-corundum refractory brick and aluminium oxide insulating brick main body is 1: 6-9.
As preferably, the Thickness Ratio of described zirconia-corundum refractory brick and aluminium oxide insulating brick main body is 1: 8.
As preferably, the surface that described zirconia-corundum refractory brick contacts with aluminium oxide insulating brick main body is rough surface.
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.
Composite fire insulating brick with inner liner of the present utility model has good heat insulating effect, and heat endurance and high temperature resistant aggressivity are good, aliquation not, anti-strip, insulation, good energy-conserving effect, long service life.
