Abstract
The utility model relates to a grid fire-proof insulating brick which comprises a fire-resisting material body and a cavity surrounded by the fire-resisting material body, wherein a thermal storage wall is arranged in the cavity and divides the cavity into at least two thermal storage cavities. The grid fire-proof insulating brick is excellent in rigidity and strength; and as the thermal insulation effect of the material is good, the grid fire-proof insulating brick is suitable to be used as a fire-resisting 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 grid fireproof insulation 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 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 grid fireproof insulation brick, and grid fireproof insulation 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 grid fireproof insulation brick comprises refractory aggregate and the cavity that is surrounded by refractory aggregate, and also has the accumulation of heat wall in the described cavity, and described accumulation of heat wall is divided at least 2 accumulation of heat chambers with described cavity.
As preferably, described accumulation of heat chamber is at least 6.
As preferably, described accumulation of heat chamber is 6-10.
As preferably, the profile of the cross section of described grid fireproof insulation brick is rectangle, square or trapezoidal.
As preferably, the profile of the cross section of described accumulation of heat chamber is rectangle, square or trapezoidal.
As preferably, the profile of the cross section of described grid fireproof insulation brick is identical with the profile of the cross section of accumulation of heat chamber.
As preferably, described accumulation of heat wall is 5-9.
As preferably, described accumulation of heat wall is perpendicular to upper surface and the lower surface of described cavity.
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.Grid fireproof insulation 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.

The cross sectional representation of Fig. 2: embodiment 2 described grid fireproof insulation bricks.
Embodiment
As shown in Figure 1, the utility model relates to a kind of grid fireproof insulation brick, comprise refractory aggregate 1 and the cavity 2 that is surrounded by refractory aggregate, and also have in the described cavity 2 perpendicular to the upper surface of described cavity and the accumulation of heat wall 3 of lower surface, and described accumulation of heat wall 3 is divided into 2 accumulation of heat chambers 4 with described cavity.The profile of the cross section of described grid fireproof insulation brick is rectangle; And the profile of the cross section of described accumulation of heat chamber is for being similarly rectangle.
As shown in Figure 2, the utility model relates to a kind of grid fireproof insulation brick, comprise refractory aggregate 1 and the cavity 2 that is surrounded by refractory aggregate, and also have in the described cavity 1 perpendicular to the upper surface of described cavity and the accumulation of heat wall 3 of lower surface, and described accumulation of heat wall 3 is divided into 6 accumulation of heat chambers 4 with described cavity.The profile of the cross section of described grid fireproof insulation brick is rectangle; And the profile of the cross section of described accumulation of heat chamber is rectangle.
The above; it only is preferred embodiment of the present utility model; can not be interpreted as limiting scope of the present utility model with this, the embodiment of all distortion that is equal to of making in the claimed scope of claims of the present utility model and change is all in the utility model scope required for protection.
