Abstract
The utility model relates to a fire-resistant insulating brick with a cavity. The fire-resistant insulating brick comprises an aluminum oxide insulating brick main body. A cuboid groove is arranged on one main plane of the aluminum oxide insulating brick main body, a zirconium corundum fire-resistant face brick is embedded in the cuboid groove inwards from the outer surface of the cuboid groove and is only partially embedded in the cuboid groove so that a cuboid heat storage cavity is formed. The fire-resistant insulating brick with the cavity is good in heat stability and high-temperature corrosion resistance, free of flaking, resistant to stripping, good in heat-insulating and energy-saving effect and long in service life. The fire-resistant insulating brick with the cavity is suitable for serving as a fire-resistant material to be used.
Description
Technical field
The utility model relates to a kind of refractory materials, and more particularly, the utility model relates to a kind of fireproof insulation brick with cavity.
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 fireproof insulation brick with cavity, fireproof insulation brick with cavity 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 fireproof insulation brick with cavity, it is characterized in that comprising aluminum oxide insulating brick main body, a principal plane of described aluminum oxide insulating brick main body offers the rectangular parallelepiped groove, described rectangular parallelepiped groove inwardly is inlaid with the fire-resistant face brick of zircon corundum from its outside surface, thereby only partly inlay described rectangular parallelepiped groove is formed with rectangular parallelepiped accumulation of heat cavity to the fire-resistant face brick of described zircon corundum.
As preferably, the exterior surface area of the fire-resistant face brick of described zircon corundum and the Area Ratio of described principal plane are 4: 9-16: 25.
As preferably, the exterior surface area of the fire-resistant face brick of described zircon corundum and the Area Ratio of described principal plane are 9: 16.
As preferably, the thickness of the fire-resistant face brick of described zircon corundum is 10-15mm.
As preferably, the thickness of described aluminum oxide insulating brick main body is 50-150mm.
As preferably, the Thickness Ratio of the fire-resistant face brick of described zircon corundum and aluminum oxide insulating brick main body is 1: 5-10.
As preferably, the Thickness Ratio of the fire-resistant face brick of described zircon corundum and aluminum oxide insulating brick main body is 1: 7.
As preferably, the surface that the fire-resistant face brick of described zircon corundum contacts with aluminum oxide insulating brick main body is uneven surface.
Of the present utility model have advantages of that the fireproof insulation brick of cavity combines 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.
