Abstract
The utility model relates to a fire-resistant hollow brick comprising an electrically-smelted zirconium corundum main body and a cavity which is encapsulated by the electrically-smelted zirconium corundum main body; in addition, the ratio of the volume of the cavity to the volume of the electrically-smelted zirconium corundum main body is 1: (2-3). The fire-resistant hollow brick keeps the advantages of excellent thermal stability, excellent high-temperature corrosion resistance, non-layering, and anti-striping performance of the electrically-smelted zirconium corundum, and meanwhile, the cavity structure is introduced to improve the thermal-insulation property of the fire-resistance material, so that the energy-saving effect is excellent. The fire-resistant hollow brick provided by the utility model is suitable for being used as the fire-resistant heat-insulation 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 refractory, hollow 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 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 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 refractory, hollow brick comprises electric fused zirconium corundum body and the cavity that is surrounded by the electric fused zirconium corundum body, and the volume ratio of the volume of described cavity and this body of electric fused zirconium corundum is 1: 2-3.
As preferably, the wall thickness of described electric fused zirconium corundum body is at least 10mm.
As preferably, the volume ratio of the volume of described cavity and this body of electric fused zirconium corundum is 1: 2.
As preferably, the profile of the cross section of described refractory, hollow brick is rectangle, square or trapezoidal.
As preferably, the profile of described cavity is regular shape or irregularly shaped.
As preferably, the profile of the cross section of described cavity is rectangle, square or trapezoidal.
As preferably, the profile of the cross section of described refractory, hollow brick is identical with the profile of the cross section of cavity.
As preferably, the profile of the profile of the cross section of described refractory, hollow brick and the cross section of cavity is rectangle.
As preferably, the profile of the profile of the cross section of described refractory, hollow brick and the cross section of cavity is trapezoidal.
The utility model has kept the electric fused zirconium corundum thermostability and high temperature resistant aggressiveness is good, aliquation not, and the advantage of antistripping has been introduced heat-insulating property, good energy-conserving effect that cavity structure has improved refractory materials simultaneously.Refractory, hollow brick described in the utility model has not only been saved raw materials cost from heavy and light, has also improved the over-all properties of material.
