1 proportion pledge gently tall aluminous brick 25 ℃ of ± of W/m.k(350 of coefficient of thermal conductivity) 0.35, this product can fall to be used for a long time in 1380 degrees high temperature, tall aluminium gets together light brick two tons, detailed price invites report to seek advice.
Light qualitative tall aluminous brick is the important heat-insulating material on kiln of hot project furnace, of light qualitative tall aluminous brick reasonable make with choose right reasonable use the sources of energy to having important sense. In all sorts of light qualitative heat-insulating material, of light qualitative tall aluminous brick fireproof degree of tall, unit weight is little; Raw material is rich, firebrick is low-cost, it is better heat-insulating material. According to workmanship differ to light qualitative tall aluminous brick can use bubble method or add character legal system to become.
Light qualitative tall aluminous brick uses 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 ℃ .
Manage of light qualitative tall aluminous brick changes target
Does tall aluminium get together light brick much money a ton? The light qualitative tall aluminous brick of 1 proportion two tons, detailed price dials a telephone please: 13937170928 seek advice.
Production of raw material of light qualitative tall aluminous brick pledges tall aluminous brick all uses pink of grog of 3 class alumina, Al2O3 and soft qualitative clay commonly gently. Content of the R2O in 3 class alumina is 0.5 % ~ 2 % , firing temperature is between 1100~1400 ℃ . The basis experiments, the R2O in vitriol person can make photograph of Mo Laishi brilliant decompose, the R2O that has 1 % can form the vitreous photograph of 10 % and corundum, when R2O content is close to 2 % . Photograph of Mo Laishi brilliant tends disappear, and form more corundum and vitreous photograph, having catabolism to Molaishi because of R2O, the Molaishi in bringing about alumina is acicular the network structure that crystal alternates each other breaks down. Make Molaishi exists with Gu island shape in vitreous photograph, make bate temperature reduces loading to become poor with thermal stability. The R2O content with because this is right medium raw material wants special restriction, the technology noting an oar that makes foaming agent to using colophony acerbity sodium wants especially strict. TiO2 also is one of impurity with the higher content in alumina, in 3 class alumina, tiO2 enters vitreous phase more, reduce fluid photograph viscosity, be helpful for agglomeration, but go against the high temperature capability that improves light qualitative tall aluminous brick. R2O is in of aluminous grog advocate brilliant photograph all has bigger solid fusibility in Molaishi and corundum, fe2O3 begins solid frit in 1200 ℃ Yumolaishi, to frit of 1300 ℃ solid 12 % of 10 % ~ . And in corundum, 1200 ℃ make an appointment with solid frit 12 % , frit originallies about when 1400 ℃ 18 % . Below reducing atmosphere, solid fusibility is reduced, take off frit to enter vitreous phase easily. When pledging tall aluminous brick is used in reducing atmosphere gently, also should father to Fe2O3 impose restriction.
Light qualitative tall aluminous brick and the distinction that weigh qualitative tall aluminous brick pledge tall aluminous brick is one of adiabatic and fireproof data that compare ideal at present gently, have compression strength tall, coefficient of thermal conductivity function of low, heat preservation good, price is low wait for a characteristic, apply extensively already at kiln of body of kiln of channel of pottery and porcelain, roller path kiln, shuttle type kiln, wall now, material of liner of heat of all sorts of heating furnace cooking that also are used at steely industry and facilities of other hot project, heat treatment, have wide market perspective. 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 ℃ . Light qualitative tall aluminous brick, call heat preservation firebrick normally, also call adiabatic firebrick. Understand first from literal, light qualitative tall aluminous brick and the weight that weigh qualitative tall aluminous brick are disparate product. Light qualitative tall aluminous brick, also call heat insolation tall aluminous brick, its essence purpose is heat insolation and heat preservation function. Do not contact directly with furnace kiln temperature in be used normally, be wall of a kind of clingy furnace, have the firebrick product of heat insolation and heat preservation action. Weigh qualitative tall aluminous brick, also call tall aluminous firebrick, its itself weight should compare light qualitative tall aluminous brick to weigh on a lot of times, not be for adiabatic heat preservation in the process that using, more important is for fireproof temperature, in using a process normally as direct as the blaze inside kiln furnace contact, so heavy qualitative tall aluminous brick has high temperature resistant effect normally. Choose tall aluminous aluminous grog to combine saggar, press multistage burden, shape via machine pressing, high temperature is firing. Tall aluminous brick is 3 brands by alumina content cent, will assure through adjusting tall aluminous alumina and the proportion that link clay fireproof the alumina content of tall aluminous brick and high temperature resistant function, satisfy different use condition and requirement thereby. Characteristic: Compression intensity is tall, chemical stability good, porosity is low, can need according to the client's design, finish machining becomes all sorts of different product.
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.
