We are very big to the demand of firebrick in construction of industrial kiln furnace, and the fireproof product that light qualitative brick regards a kind of adiabatic heat preservation as, having very big demand likewise, be applied in structure of kiln furnace heat preservation. The tall aluminium in we letting understand series of heat preservation brick below pledges gently bricky product, and its relevant state level.
Tall aluminous light qualitative 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.
The bulk density of tall aluminous light qualitative brick 0.4 ~ 1.35g/cm3. Porosity 66% ~ 73% , compression intensity 1 ~ 8MPa. Heatproof shake performance is better. The dimension of GB brick is 230*114*65mm.
Manage of tall aluminous light qualitative brick changes target:
Can see from inside pointing to plotting, my factory tall aluminium pledges bulk density of the brick is 1.0g/cm3 gently, 3.5MPa of prep above of intensity of normal temperature compression, coefficient of thermal conductivity is under 0.40W/m · K, compound state level, it is high quality fireproof product.
Tall aluminous light qualitative 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 ℃ of 1300 ~ 1500 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 firebrick distinguishs with what weigh qualitative firebrick: The effect with light qualitative main brick is to use heat preservation, reduce caloric prediction of a person's luck in a given year. Be like: Brick of tall aluminous light qualitative brick, Mo Laishi heat preservation; And firebrick basically is to use the broil that experiences flare-up to bake. Convention pledges the brick won't contact blaze directly commonly gently, and firebrick contacts blaze directly commonly. Be like tall aluminous brick; Corundum not comes stone brick.
Main distinction has the following:
1, heat preservation function. The coefficient of thermal conductivity of light qualitative brick is in commonly 0.2-0.4 (average temperature 25 ℃ of 350 ± ) W/m.k, and the coefficient of thermal conductivity of firebrick is in 1 (average temperature 25 ℃ of 350 ± ) W/m.k above, many the heat preservation performance that can reach the heat preservation function of heat preservation brick wants to compare firebrick from this is good.
2, fireproof degree. Of light qualitative brick fireproof degree be in 1400 degrees commonly the following, and those who weigh qualitative brick is fireproof degree in 1400 degrees of above.
3, density. Light qualitative brick is light qualitative insulation material commonly, density is in commonly 0.8-1.0g/cm3, and the density of firebrick is in basically 2.0g/cm3 above.
Light qualitative brick and heavy qualitative brick cooperate to use, collocation is fireproof and pouring makings, ability compose builds a good industrial kiln furnace. When we are using light qualitative brick, need the more sufficient property that knows light qualitative brick. Light qualitative brick serves as tall aluminium to pledge gently quantity huge is used in the brick a kind of product, the brick that use state level produces can better tie-in and other fireproof data is used together.
