AZS Brick Introduction
Fused cast zirconia corundum brick, the English abbreviation is AZS, , it is according to three chemical constitution of Al2O3－Zr02－Sio2 ternary diagram, ranked by the content of them, select “Z” from Zr02, select “S” form Sio2. National standard adopts this abbreviation, such as 33 fused zirconia corundum brick, abbreviated to AZS33#, 36 fused zirconia brick, abbreviated to AZS36#, 41 fused zirconia corundum brick, abbreviated to AZS41#. 33,36 and 41 are named according to the content of Al2O3. For example, fused zirconia corundum brick AZS41 is refer to the fused zirconia corundum brick contained with the content of 41% alumina oxide.
AZS Brick properties
- Strong glass corrosion resistance and high thermal shack stability.
- Good wear-resistance,dregs-resistance and alkali corrosion resistance.
- High-purity raw material, barely no pollution.
AZS Bricks Application
Fused cast zirconia-corundum refractory bricks are mainly used in glass industrial kiln.
AZS Bricks Types Used in Glass kiln
AZS33# brick is the most widely used product in the series of AZS products, AZS33# brick has superior performance in depollution of glass liquid.
AZS 36# bricks have excellent performance in AZS series, with the properties of strong erosion resistance to glass liquid and low pollution. AZS 36# brick is usually used in the key parts of wall of glass furnace near the melting tank.
AZS 41# bricks has the best performance of the AZS series, with the strong corrosion resistance to glass phase and the property of high exudation temperature of glass furnace, low pollution to glass liquid. AZS 41# brick is widely used in wall of glass furnace hot spots, dog-house, throat, furnace ridge and full electric melting furnace.
