Building the insulation material that wall body uses is product of commonner heat preservation heat insolation, do not have exorbitant requirement to temperature, the material temperature that kiln furnace uses is higher, a few Baidu reach more than 1000 degrees, temperature, material pledges and the price is bigger distinction.
Energy-saving insulation material includes wall system organic kind (be like benzene board, get together benzene board, squeeze model board, polystyrene polyurethane of bubble of bubble board, horniness, polycarbonate and phenolic aldehyde) , inorganic kind (like pearlite floor slab of floor slab, bubble, compound silicate, cliff, heat preservation prevents crack material: (cloth of steel wire of electric welding net, galvanizing, reseau) .
Insulation material has kiln furnace to pledge heat preservation brick is waited a moment module of blanket of siliceous aluminous fiber, felt, cotton, fiber, gently, can choose according to temperature 800 to 1100, 1300 degrees of high temperature that reach above pledge gently material.
Cotton of aluminous heat preservation of silicon acid of cotton of siliceous aluminous heat preservation is will aluminous aluminous melt, a kind of heat preservation that blows law or centrifugal legal system to become with gush is fireproof material. Cotton of siliceous aluminous heat preservation differs according to the raw material of fireproof material cent is microtherm, medium lukewarm, high temperature 3 kinds of heat preservation are fireproof material, average use temperature is unfavorable more than 1400 ℃ .
Blanket of siliceous aluminous fireproof fiber is raw material with siliceous aluminous fireproof fiber, use the fireproof fiber that craft of dry method pinprick makes. Swing silk to become fine continuously with dry method, pinprick makes carpet, it is contemporary and advanced production technology. Fireproof fiber blanket not only soft and rich flexibility, tensile strength is high, and have good treatment performance and construction property. The heavy qualitative, light qualitative fireproof data that fireproof fiber blanket basically uses siliceous aluminium to replace a tradition makes heat insulation of the village inside furnace of high temperature industry or conduit of the high temperature that wrap Fu wait, can reduce furnace wall thickness original 1/2 commonly, furnace wall quality can reduce original 1/5-1/10. Do not need drying-out, can use prefab method to build furnace, shortened the time that build furnace, energy-saving effect is good.
All sorts of siliceous aluminium gush boast fiber rug, what be blown into fine craft production by gush is common model, high pure model, tall aluminium, contain pinprick of classics of cotton of zirconium siliceous aluminous fiber, heat to finalize the design, vertical transversely, dozen roll wait for working procedure to be made. All sorts of pinprick blanket are divided have corresponding breed to come loose outside the good performance with same cotton of aluminous fiber of shape silicon acid, have good tensile strength. Pinprick blanket quality of a material is even, exterior level off.
The adiabatic and refractory products of the Al2O3 content 30%-48% that brick of argillaceous heat preservation makes for main raw material with fireproof clay 5 use fireproof clay, float bead, fireproof clay grog makes raw material, mix into is added bond and curium wood chip classics cooperates, mix, shape, dry, firing, can make the product that gets bulk density 0.3~1.5g/cm3, output occupies above of half of heat preservation brick. Range of application of brick of argillaceous heat preservation is wide, multi-purpose the thermal insulation in hot project facilities and industrial kiln furnace, can use at having stock of melt of intense high temperature to erode to reach erode the place of action, a fireproof coating, reduce the furnace that be mixed by slag to enrage soot to erode, decrease mar, the working temperature of goods does not weigh the experiment temperature of the change that burn a line more than. Brick of argillaceous heat preservation belongs to much stoma kind a kind of light qualitative insulation material. Porosity of this kind of material is in 30%〜50% , sex of its heat preservation is poor, but mechanical strength is as better as the function that fight corrode.
Tall aluminium gets together light brick also calls tall aluminium to get together light ball brick 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 a characteristic. Get together price of light tall aluminous brick is in ~1850 yuan 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.
JM series Mo Laishi gets together Mo Laishi of brick of light heat preservation gets together dimension of norms of light brick standard is 230*114*65mm, bulk density is in commonly 0.6-1.2g/cm3, use temperature 1300 degrees - 1550 degrees. Different dimension can pursue order do. According to use temperature cent is JM-23, JM-26, JM-28, JM-30 these a few kinds of model. This kind of product can contact blaze directly, have spend tall, coefficient of thermal conductivity high temperature resistantly, gently small, energy-saving effect compares the characteristic such as ideal.
Silicon of light qualitative silica brick pledges adiabatic firebrick calls light qualitative silica brick normally, finely silica basically is used to make raw material when making, its are critical granuality does not exceed 1mm normally, and the grain that is less than 0.5mm among them not less than 90% . In the pug that makes light qualitative silica brick, general mix into enters 35-45% anthracitic or 30% right-and-left coke serve as can light add thing, its granuality is less than 1mm. Choose and add a capacity of the bond in pug, mineralizer basically as identical as production silica brick.
Of light qualitative silica brick fireproof spend as identical as composition common silica brick to differ not quite, why because air hole is very much, the reason compression intensity, sex that fight broken bits, sex that fight corrupt be inferior to common silica brick. The use temperature of light qualitative silica brick does not exceed 1550 ℃ , do not contact directly with stock of high temperature melt, do not accept aggressivity gas action continuously.
Hollow ball brick uses alumina hollow ball and alumina pink are alumina main raw material, combine other bond, become through fire of 1750 degrees of high temperature; Al2O3 content prep above 90 ％ . Belong to high temperature material a kind of energy-saving insulation material, extraordinary stability is used below all sorts of atmosphere. Apply at be on furnace of high temperature kiln especially. Hollow ball can be used at doing high temperature filling of heat insolation of fireproof, high temperature, high temperature is fireproof concrete pledges collect expects gently, high temperature is pouring makings. Hollow ball brick can be used at high temperature to pour furnace of furnace of club of furnace of silk of blaze kiln, shuttle type kiln, molybdenum, tungsten, induction, nitrogen to change furnace to wait. To reducing weight of body of heater, transform structure, managing material, economic energy resources, all can obtain apparent effect
Hollow ball brick can be in zirconia one kind the high temperature of 1800-2400 ℃ is energy-saving model small qualitative particular kind is fireproof material. Because the thermal conductance of this kind of goods is 0.3-0.4WW/m.k(350 ± 25 ℃ ) - 1, make adiabatic lining material not only on marvellous furnace of furnace of all sorts of muffle furnace, aluminous silk, tungsten, OK still and direct charge for the making of sth. makes the lining material of the layer.
