Tall aluminous light qualitative brick and tall aluminium get together light brick is certain distinction. Use technology of the requirement, quantity that contain aluminium, production, price to wait a moment for example. Tall aluminium gets together light brick and light qualitative tall aluminous brick contain aluminous amount, sheet is heavy, on use temperature, on color, it is the tall aluminium that distinguishs somewhat gets together on performance characteristics light brick also calls tall aluminium to get together light ball brick, it is with special type high furnace charge is main raw material, complementary use with proper additive get together to burn the production that break a law gently. Goods has strength tall, thermal stability is good, the heavy change that burn fine is little, coefficient of thermal conductivity is small wait for an advantage. Tall aluminium gets together light brick item characteristics: 1, tall;2 of high temperature intensity, be able to bear or endure it is good that all sorts of atmospheres corrode;3, admirable thermal shock to stabilize function;4, thermal insulation;5, energy-saving effect is distinct wait for a characteristic. Light qualitative tall aluminous brick calls tall aluminium adiabatic brick again. Alumina content is in 48% above, main the light qualitative fireproof material that constitutes jointly by Molaishi and vitreous photograph or corundum. Bulk density 0.4~1.35g/cm3. Porosity 66%~73% , compression intensity 1~8MPa. Heatproof shake performance is better. Use tall aluminous aluminous grog to add a few clay normally, law or bubble law produce with gas after classics mill with slop form pouring, figuration, via 1300 ～ 1500 ℃ are firing. Also can replace partial alumina grog with industrial alumina sometimes. With the liner that builds kiln furnace at build by laying bricks or stones and thermal insulation, and erode without stock of melt of intense high temperature reach erode the place of action. When be being contacted with blaze directly, temperature of watch surface contact does not get prep above 1350 ℃ . The aluminous raw material that according to different grade the quality of tall aluminous brick asks to choose different grade, be helpful for reasonable use, product essence matchs, do not use as far as possible mix the raw material with serious step. The quality of clinker depends on to calcine temperature, normally to calcine temperature should be achieved or the firing temperature of alumina of summary prep above, in order to make sure sufficient agglomeration mixes clinker as far as possible high bulk density, make 2 times not come petrifaction and agglomeration systole action are finished in to calcine process. Tall aluminium gets together light brick, get together light tall aluminous brick also calls tall aluminium to get together light ball brick is it is main raw material with makings of special type blast furnace, complementary use with proper additive get together to burn the production that break a law gently. Goods has strength tall, thermal stability is good, the heavy change that burn fine is little, coefficient of thermal conductivity is small wait for an advantage. Get together price of light tall aluminous brick is in 1800-2000 is multivariate a ton, also differ according to the difference price of aluminous content, this is market reference price, particular value needs to produce the decision after manufacturer talks things over with firebrick. Get together the AL2O3 content of light tall aluminous brick 60% above, fireproof temperature 1600 degrees, specific gravity 0.4-1.35g/cm3, 1-8MPA of intensity of porosity 0.66-0.73% compression. Tall aluminium of tall aluminous light qualitative brick pledges the brick calls heat preservation firebrick normally gently, call tall aluminous adiabatic brick again. Alumina content is in 48% above, main the light qualitative fireproof material that constitutes jointly by Molaishi and vitreous photograph or corundum. Bulk density 0.4-1.35g/cm3. Porosity 66%-73% , compression intensity 1-8MPa. Heatproof shake performance is better. Use tall aluminous aluminous grog to add a few clay normally, law or bubble law produce with gas after classics mill with slop form pouring, figuration, via 1300 ～ 1500 ℃ are firing. Also can replace partial alumina grog with industrial alumina sometimes. It is to use clinker to combine clay to be made for tall aluminous alumina and raw material, its manage changes function to see figure below. Use bubble likely now law and light a way, get porosity thereby density of tall, bulk the light qualitative tall aluminous brick with low, low thermal conductance. Light qualitative adiabatic brick also can say for brick of light qualitative heat preservation, its characteristic is density performance of lower heat preservation is better, according to the product different, light qualitative tall aluminous brick can be used at build by laying bricks or stones to build thermal insulation and reach without stock of be in harmony of furnace of intense high temperature erode action place. With the liner that builds kiln furnace at build by laying bricks or stones and thermal insulation, and erode without stock of melt of intense high temperature reach erode the place of action. When be being contacted with blaze directly, temperature of watch surface contact does not get prep above 1350 ℃ . Its look the function is heat preservation and heat insolation constitutionally, do not contact directly with furnace kiln temperature normally in be used normally, it is wall of a kind of clingy furnace, have the firebrick product of heat insolation and heat preservation action. It is to use clinker to combine clay to be made for tall aluminous alumina and raw material, its manage changes function to see figure below. Use bubble likely now law and light a way, get porosity thereby density of tall, bulk the light qualitative tall aluminous brick with low, low thermal conductance. Light qualitative adiabatic brick also can say for brick of light qualitative heat preservation, its characteristic is density performance of lower heat preservation is better, according to the product different, light qualitative tall aluminous brick can be used at build by laying bricks or stones to build thermal insulation and reach without stock of be in harmony of furnace of intense high temperature erode action place. Of light qualitative tall aluminous brick firing in fire of light qualitative tall aluminous brick, often contain the foreign matter oxide such as R2O, RO, Fe2O3. They and Al2O3 and SiO2 make fluid appearance in the reaction below high temperature. In Al2O3 in one SiO2—R2O system, the growth rate that below high temperature fluid photograph estimates as temperature rise and accelerate. Such, a large number of addition that what because carry high fever,bring fluid photograph amount into temperature, of fluid photograph viscosity reduce what can bring about a brick to be out of shape of the high temperature capability that reach a brick reduce. Reason is in the agglomeration process that gives priority to with fluid photograph agglomeration, appropriate is used inferior firing temperature and longer heat preservation time. Manufacturing practice makes clear, tall aluminous brick can use one class, 2 level same and firing temperature. Use blaze when kiln is firing, it is 1430 ℃ commonly, heat preservation 40h; The tall aluminous brick such as Ill is 1390 ～ 1420 ℃ . With channel when kiln is firing, it is 1550 ℃ and ℃ of 1450 ～ 1500 respectively. Tall aluminous brick uses weak oxidation atmosphere commonly firing. Tall aluminous light qualitative brick and tall aluminium get together the manufacturing technology with the both distinction of light brick is different, its price somewhat difference, detailed price invites report to seek advice. 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.
