According to what firebrick and heat preservation brick choose?

Want the design requirement according to kiln furnace, for example firebrick of wear-resisting of excel in of wear-resisting place need, without wear-resisting the requirement needs the place of heat preservation heat insolation, use heat preservation brick, kiln furnace liner has layer of heat preservation thermal insulation, wear-resisting to wait mutiple level undertake assorted. The discriminative firebrick of high temperature firebrick and brick of light qualitative heat preservation is the build by laying bricks or stones with high temperature commonly used industry builds liner material, how to choose firebrick is user consideration to want an end. Firebrick cent is high temperature firebrick and brick of light qualitative heat preservation, do not know how to choose, cheng Naicai of flourish of Henan firebrick manufacturer is small make up the distinction that tells you them. Firebrick attachs most importance to qualitative firebrick by weight cent (high temperature firebrick) with light qualitative firebrick (brick of light qualitative heat preservation) two kinds, heavy qualitative firebrick is commonner brick of argillaceous brick, tall aluminous brick, silica brick, corundum waits; Pledge firebrick has gently: Light qualitative Molaishi is brick of brick, light qualitative clay, light qualitative silica brick, light qualitative tall aluminous brick. Weigh qualitative firebrick: Place of lukewarm wear-resisting of commonly used Yu Naigao, main effect is high temperature resistant, wear-resisting, be able to bear or endure chemistry is eroded etc, apply at the place that as straight as the blaze inside kiln furnace knot contacts, so heavy qualitative firebrick is had commonly higher fireproof temperature and use temperature. Brick of light qualitative heat preservation: It is to reduce heat energy loss, remove a kind of firebrick of effect of adiabatic, heat preservation, not tall, wearability needs strength, cannot contact high temperature blaze; Commonly used the material of adiabatic heat-insulation layer that builds liner at build by laying bricks or stones. Weigh the main distinction of qualitative firebrick and brick of light qualitative heat preservation: (1) function of adiabatic heat preservation: The coefficient of thermal conductivity of light qualitative brick is in commonly ℃ of 350± of 0.2-0.4(average temperature) W/m.k, and the coefficient of thermal conductivity of heavy qualitative brick is in ℃ of 350± of 1.0(average temperature) W/m.k above. (2) fireproof temperature: Those who weigh qualitative firebrick is fireproof degree in 80 ℃ above, the fireproof temperature of brick of light qualitative heat preservation is commonly under 00 ℃ . (3) bulk density: Density of brick of light qualitative heat preservation is in commonly 0.8-1.0g/cm3, the density of heavy qualitative firebrick is in at all 2.0g/cm3 above. (4) compression intensity: The compression intensity of heavy qualitative firebrick is in 40MPA above, the compression intensity of brick of light qualitative heat preservation is under MPA. (5) performance characteristics: Heavy qualitative firebrick is had stronger fight mechanical concussion, be able to bear or endure chemistry is eroded, wear-resisting function, brick of light qualitative heat preservation has property of taller adiabatic heat preservation. (6) use place: Heavy qualitative firebrick is commonly used the working layer at contacting blaze or intermediate layer material, brick of light qualitative heat preservation can be used at material of adiabatic heat-insulation layer only. Overall for: The mechanical intensity of heavy qualitative firebrick is tall, chemical stability is good, do not react with stock fit chemistry and high temperature resistant performance is good, tall heat-resisting temperature can arrive at 00 ℃ above. Light qualitative firebrick is to use temperature for a long time to be under 00 ℃ , it is the material of wall of heat of heat of a kind of clingy kiln. The difference of high temperature firebrick and brick of light qualitative heat preservation is very big, their use environment, limits, effect each are not identical. When purchase, we want a basis actual condition, choose appropriate firebrick. 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.
