Description
High alumina fused cast products is produced by melting and casting high
purity alumina in electric furnace at 2000C. High alumina fused cast blocks
is formed when alpha alumina inter-combine during their crystallization
stage. A very compact structure is then formed; it has excellent endurance to
strong alkali. Under 1350C, the corrosion resistance to glass melt is the same
as AZS products. Because it does not contain impurities such as Fe2O3 and
TiO2, when comes into contact with liquefied glass, air bubbles are rarely found.
Therefore, this product has the special characteristic of minimizing
contamination to glass liquor. So it is very suitable for sidewalls, pond bottoms,
fore-hearth feeders of slap-up glass kiln.
Typical chemical composition:
AL2O3 no less than 95%
SiO2 no more than 0.5%
Fe2O3+TiO2+CaO no more than 0.5%
Na2O remnant
