Heat preservation brickUse at adiabatic heat preservation, reduce hot loss, it does not contact blaze directly commonly. FirebrickContact blaze directly normally, it faces the broil of kiln ingle blaze to bake directly, because they are madeUsed position differs somewhat, so of firebrick fireproof degree of photograph is tall to wanting, so the density between them and function also differ somewhat.
First, of heat preservation brick fireproof degree it is commonly under 1400 ℃ , and of firebrick fireproof degree in 1400 ℃ above, fireproof the motive that spends different play is different also, use result is not same also. Next, the density of heat preservation brick is 0.8-1.0g/cm3 commonly, it is a kind of light qualitative insulation material, and the density of firebrick is in basically 2.0g/cm3 above, density is different, so itPeople quality is different. Again, the coefficient of thermal conductivity of heat preservation brick is in commonly 0.2-0.4w/m.k, and the coefficient of thermal conductivity of firebrick is in 1.0w/m.k above, so the heat preservation function of heat preservation brick wantsThe heat preservation performance that compares firebrick is a lot of better.
