Kiln furnace uses glass to pledge density of bulk of Mo Laishi brick is gently: 0.6, 0.8, 1.0g/cm3, mark brick dimension is 230*114*65MM, the weight of single block brick is: 1KG, 1.36KG, 1.7KG, one ton has 1000, 735, 588.
Vitreous kiln furnace pledges with light simple fireproof stuff fireproof material belongs to heat preservation heat-insulating material gently, can reduce kiln body to come loose hot, save the sources of energy, also can reduce kiln body weight at the same time, reduce cost. Light fireproof material includes light insulation firebrick, siliceous aluminous fiber to wait; Light insulation firebrick can divide with raw material by place for: One, clay is qualitative (use at heat preservation of the bottom inside flue heat preservation, regenerator and pool bottom, ) of ℃ of applicable temperature 900~1200; Aluminium is qualitative (the heat preservation outside upside of the wall outside be being used at small furnace top, regenerator and parapet and Chi Bi, ) of ℃ of use temperature 1350~1500; 3, silicon is qualitative (the roof heat preservation of the roof that turns a department with Yu Rong, roof of working ministry and regenerator, ) of ℃ of use temperature 1400~1550; 4, light qualitative Molaishi brick (the wall outside the side outside regenerator and parapet and Chi Bi, ) of ℃ of use temperature 1500~1550; 5 it is siliceous aluminous fiber belongs to noncrystalline fiber, basically have: Common model, use temperature is 1000 ℃ ; High pure model, use temperature is 1100 ℃ ; Tall aluminium, use temperature is 1200 ℃ . Mo Laishi brick, weight is light.
Light qualitative Molaishi bricky quality effect of light, heat preservation is good, it is makings of high quality high pure and fireproof pink, press product demand proportion, join organic and compound filling, via vacuum extrusion, high temperature agglomeration makes product of light qualitative Mo Laishi, the light qualitative Molaishi that flourish Cheng Naicai produces bricky basis is different norms, alumina content is in 50%-80% .
But because Molaishi is mineral exiguous, can pass artificial synthesis only, synthesize Molaishi to mix by certain proportion, ability forms the stable compound in this system below constant temperature, not come namely stone crystal. Compositive AL203 of Mo Laishi is about 79% , SI02 is about 21% , but a certain quantity of impurity is contained in raw material, the reaction of constituent is caused in the meeting below high temperature, foreign matter constituent is so more, glassy jump over with corundum content much, mo Laishi forms structure of thick any crystalline substance, bring about goods porosity to increase, thermal shock stability drops with the sex that fight corrode, easy generation crackle.
Accordingly, manufacturing technology of Mo Laishi basically has agglomeration craft and electric frit technology. With industrial alumina, hydroted alumina and pure clay (the kaolin of small foreign matter) reach Xie Lashi to wait for raw material, it is raw material with tall aluminous alumina, it is binder with tall aluminous alumina, or synthesize Molaishi with tall aluminous alumina directly, produce brick of Mo Laishi heat preservation to wait for a product.
A kind of light qualitative Molaishi brick, give priority to brilliant photograph with Molaishi. Mineral in outside dividing Molaishi, alumina content is low mineral in still contain a few vitreous photograph and Fang Shiying; Content is high mineral in contain a few corundum, and fireproof sex is good.
Mo Laishi pledges gently fireproof intensity of the brick is higher, achieve 1790 ℃ above. Begin the temperature 1600~1700 ℃ of bate loading. Often press compression intensity to be between 70~260MPa. Heat-resisting performance is good. Electric frit Mo Laishi has agglomeration Mo Laishi and electric frit Mo Laishi two kinds. It is main raw material with tall aluminous aluminous grog, join a few clay or unripe alumina to make binder, agglomeration not comes stone brick, after shaping firing. It is raw material with alumina of tall alumina, industry and saggar, join charcoal or coke fine grained to serve as reducer, classics Mo Laishi brick is produced with law of reductive report frit after shaping. The crystallization that the crystallization of electric frit Mo Laishi compares agglomeration Mo Laishi wants big, its fight goods of agglomeration of excel of thermal shock function. Its high temperature capability basically depends on of alumina content and Molaishi and glass distributing equably. The blind angle lining that applies to system of splitting decomposition of kiln of agglomeration of regenerator of furnace of kiln of shaft of hot-blast stove roof, blast furnace and hearth, glass, pottery and porcelain, oil.
Frit kiln uses vitreous report to pledge Mo Laishi brick pledges bricky condole installs Molaishi to have crucial advantage on function gently gently, make frit kiln area use it basically to make condole carry a structure on the head in the electric frit kiln of 8m2 above at present. From kiln of small-sized report frit and kiln of large report frit two respects developed a trend to undertake an analysis to its. One, is the brick in light qualitative Molaishi is the application on small-sized electric stove small electric frit kiln (fused area 1? 8m2 is less than 1m2, do not discuss the) inside limits in the article, the main factor that its popularize is cost, at present domestic share manufacturer has been used, but had not gained ground completely. As a result of raw material cost reduce and the people attention to resource recycle, believe in kiln of small-sized report frit use suspension bridge will have larger development space. 2, the brick is in light qualitative Molaishi the application in kiln of large report frit in last few years, the fused area of electric frit kiln is larger and larger (fused area is more than 20m2) , this posed new challenge to the design of kiln canister. Because increased promotion extent, accordingly weight increases, the fission formula that uses to assure to promote a face to be able to repeat promotes a structure, principal part of each fission type cent becomes 3 parts, every part bears the weight of respectively, promotion can have respectively when assembling and unassemble.
Pledge the use note of Mo Laishi brick pledges the brick chooses Molaishi gently gently natural material of tall aluminous low iron, the adiabatic firebrick that the structure gives priority to with photograph of Mo Laishi brilliant, have compression strength tall, thermal stability is good, coefficient of thermal conductivity is low, impervious capability is strong, be able to bear or endure erode, can use extensively at the industry such as metallurgy, petrifaction, mechanical, pottery and porcelain, make the liner of industrial furnace kiln or thermal insulation, it is long life, energy-saving good product. Can ask to increase Mu Fenhe to get together according to the user benzene spherule, production gets together brick of heat preservation of light Mo Laishi.
Attention: 1. Classification temperature is to show fireproof material heats to contract to the line the 2% temperature when, unfavorable as the basis that chooses temperature. 2, when with light qualitative Molaishi the brick is fireproof working face, the high temperature inside kiln is a when decide to choose sort of light simple fireproof stuff main factor, place choosing not comes gently character the working temperature of stone brick should inside prep above kiln ℃ of 100-300 of real work temperature; The choice pledges the type of Mo Laishi brick consults please gently index of bate of its to load; Bulk density and the quantity that contain aluminium can ask to adjust according to the user.
Kiln furnace uses glass to pledge furnace of kiln of glass of bricky bulk density uses Molaishi to pledge bricky bulk density is Molaishi gently gently: 0.6, 0.8, 1.0g/cm3, mark brick dimension is 230*114*65MM, the weight of single block brick is: 1KG, 1.36KG, 1.7KG, one ton has 1000, 735, 588.
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.
