Henan tall aluminium gets together light brick is fireproof degree of tall, use temperature is high, the heat preservation that basically is used at furnace of high temperature kiln is adiabatic, it is the light qualitative firebrick that has heat insulation of fireproof, heat preservation. Tall aluminium gets together light brick calls brick of light qualitative tall aluminous brick, tall aluminous heat preservation or tall aluminium adiabatic brick again, it is to show AL2O3 content is in 45% above all sorts of light qualitative firebrick. Light qualitative tall aluminous brick uses tall aluminous aluminous grog to add a few clay to be main raw material, law or bubble law produce with gas after classics mill with slop form pouring, shape, via 1300 ～ 1500 ℃ high temperature is firing. Tall aluminium gets together dimension of norms of light brick standard is 230*114*65mm, bulk density is 0.4-1.35g/cm3, porosity is 66%-73% , compression intensity is 1.3-8.1mpa, thermal conductance is 0.291-0.582w/(m.k)(350 ℃ ) , use temperature is 1350-1500 ℃ . Henan tall aluminium gets together light brick just has not had adiabatic effect, still have the effect with energy-saving heat preservation, in order to reduce specific power consumption. Accordingly, the adiabatic insulation material with development high-powered application is heat of current a research. Tall aluminium gets together light brick and traditional light qualitative firebrick are compared, have the following advantage: (1) thermal conductance is low, fall in high temperature condition especially, thermal conductance is relatively inferior, heat preservation heat proof quality is good. (Sex of 2) heatproof shake is good, inside use temperature limits, the brick is not out of shape, do not flake. (3) differs according to utility, choose reasonable mechanical intensity, make pledge gently brick each function beautiful. (Higher loading bate temperature mixes 4) to be weighed lesserly burn metabolic ratio, pledge with similar material firebrick photograph is compared gently character, use temperature is higher, life is longer, safer. Get together light tall aluminous brick chooses high quality tall aluminium clinker and high pure clay, with fill of polystyrene bubble ball, classics is firing light the brick of light qualitative tall aluminium that forms stomatic heat insolation. Get together even low heat conduction leads structure of tall aperture of purity of raw material of characteristic of light tall aluminous brick, intensity of low thermal capacitance is high, dimension precision gets together high light tall aluminous brick is applicable kiln of all sorts of channel of heat preservation of heat insolation of industrial kiln furnace, warm-up of roller path kiln paragraph, cool paragraph of liner. Brick of aperture of roller of roller path kiln, reach low in liner of lukewarm resistor furnace. Henan tall aluminium gets together light brick is current the good insulation material in design of industrial kiln furnace. The kiln furnace liner that applies extensively at the industry such as metallurgy, mechanical, pottery and porcelain and chemical industry (do not suffer solution erode) and heat-insulation layer, it is a kind of good energy-saving product. Its use temperature is to be in under 1350 ° C. Tall aluminous qualitative adiabatic firebrick can be used at build by laying bricks or stones to build thermal insulation and erode without stock of melt of intense high temperature reach erode the place of action. Fireproof material occurrence craze, fall off, easy how to wear away to do? Want to solve a problem thoroughly, need to be dug from germ, the analysis gives real reason, flourish Cheng Naicai is engaged in be able to bear or endure service of timber production, research and development is old, can solve all sorts of difficulty problems of liner of furnace of high temperature kiln, welcome broad new old friend to seek advice reach technical communication.
