Firebrick and heat preservation brick which good?

Firebrick and heat preservation brick belong to boarding refractory products, but, one is to pledge again fireproof, wear-resisting, one is heat insolation of light qualitative heat preservation, utility of two kinds of commodity is distinguished somewhat, basically be form a complete set completely (combine) apply.


Firebrick of firebrick 　 　 (boarding is able to bear or endure material) cent attachs most importance to qualitative brick and light qualitative brick (adiabatic brick, heat preservation brick) , be mix by a variety of fireproof raw material, puissant suppress, be able to bear or endure to baked wheaten cake writtens guarantee and be become, material is qualitative abundant diversity, the firebrick sort that flourish Cheng Naicai produces is all ready, can order make, can satisfy at present level of furnace of all sorts of kiln of fireproof high temperature use a condition. Heat preservation brick is the negative charge that reduces fireproof liner, the figuration of heat preservation heat insolation, managing the sources of energy is able to bear or endure material, place pledges with material basic and as identical as firebrick, bricky system interior and surface are distributinging on average stomatic, what pledge according to material is different, some cannot blaze of bring into contact with, some is OK blaze of bring into contact with. What does commonner firebrick have? Basis material has saggar, one class character tall aluminium, Molaishi, Bai Gangyu, silicon pledges magnesian, carbon is waited a moment character character, gently. . . . . . Saggar brick is low-cost, use is extensive, chemistry is weak acidity, of this commodity fireproof degree spend for 1580-1750, loading bate high temperature is 1300 degrees - 1400 ℃ , the high temperature of brick of light qualitative heat preservation is met specific gravity qualitative brick is a few lower, this product has those who had held out to be able to bear or endure urgent cold urgent hot property. Half silica brick is by quartz and fireproof foolish earth mixes mixture production to go out, chemistry is half acidity, it is to be used at converter, electric stove and cupola to wait. Tall aluminous brick is 3 oxygen the 2 content that melt aluminium are higher than saggar goods, AL2O3 occupies than be: 48 ％ - ≥ the firebrick of 82% , other part is oxidation silicon. The sex fighting broken bits of this commodity is better, fight pressure density is big also, carry on one's shoulder is soft reach 1550 degrees for 1420 degrees, have fired brick and do not bake bricks, silicon is qualitative fireproof material, it is chemistry to be able to bear or endure aciditily material, the 2 oxidation silicon in commodity occupies the 93 ％ above of overall raw material, join by 2 oxidation silicon lime is become with fire teaching earth. The carry on one's shoulder of silica brick is soft be close friends than saggar, tall aluminous brick, loading bate high temperature is almost adjacent and fireproof degree, but the heatproof shock effect of this commodity is not ideal, it is at present it is to be used at the firebrick of steel-making furnace, graphitization roast furnace and vitreous forge. Magnesia brick, magnesium is able to bear or endure character material, chemistry is alkalescent, magnesian the 85 ％ left and right sides that takes total part. What although having,had held out is fireproof degree, 2000 ℃ above, but, the heatproof shake of this commodity is not ideal. It is to be used at alkalescent open-hearth furnace, electric stove and furnace of nonferrous metal metallurgy to wait.


What does brick of heat preservation of 　 of 　 of heat preservation brick have? Heat preservation brick is the light qualitative firebrick that often says, commonner brick of light qualitative saggar, tall aluminium gets together light brick, mo Laishi gets together light brick and light qualitative silica brick are waited a moment. . . . . . Brick of saggar heat preservation calls clay qualitative adiabatic brick again is be with fireproof saggar is the alumina ingredient that raw material mixes production to go out pledge gently for the heat insolation of 48% brick. Its produce craft work burn oneself out to add content law and bubble way. 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, high quality of this commodity operation is fireproof raw material raw material, with get together light ball is made burn lost property, exercise manufactures technology complexly, be able to bear or endure to baked wheaten cake writtens guarantee and be become through exercise channel kiln, of this commodity fight press stability of density and fireproof function, thermal shock to be able to be behaved admirable, use extensively at in furnace of kiln of fireproof industry high temperature. Mo Laishi pledges heat preservation brick is new-style be able to bear or endure material, this commodity alumina is occupied than 50-60% , apply high temperature to be 1260-1650 ℃ , but blaze of direct bring into contact with, have high temperature resistant, small the heatproof shake performance with degree of tall, small, good coefficient of thermal conductivity, energy-saving effect to wait for a characteristic significantly. It is the heat preservation firebrick with high quality heatproof shock at present exceedingly good effect. Firebrick and heat preservation brick which good? This can not compare a gender, flourish Cheng Naicai suggests: Only the basis applies a condition to find appropriate and refractory products in detail.
