Fused Cast AZS Refractory Brick for Glass Furnace Refractories
The Description:
Fused zirconium corundum brick also known as AZS fused zirconium corundum brick, AZS brick, fused cast AZS brick, etc., the English abbreviation is AZS, is according to Al2O3- - Zr02- - Sio2 ternary phase diagram of the three chemical components, according to the order of their content, Al2O3 takes A, Zr02 takes Z, Sio2 takes S, the standard uses this abbreviation, such as 33 fused cast zirconium corundum brick, abbreviated as AZS33#, 36 fused cast zirconium corundum brick, abbreviated as AZS36#,41 fused cast zirconium corundum brick, Abbreviated as AZS41#. Among them, 33, 36, 41 are named according to the content of alumina (Al2O3), such as fused zirconium corundum brick AZS41# refers to the fused zirconium corundum brick with 41% alumina content, fused zirconium corundum brick AZS36# refers to the fused zirconium corundum brick with 36% alumina content. Fused zirconium corundum brick AZS33# refers to fused zirconium corundum brick with 33% alumina content

Structure characteristics of fused zirconium corundum brick:
Fused zirconium corundum brick is a white solid formed by melting and internalization of pure aluminum oxide powder and zirconium sand containing about 65% zirconia and 34% silica in an electric melting furnace and then injected into the model for cooling. Its petrographic structure is composed of eutectoid and glass phase of corundum and zirconium clinite. From the perspective of facies, it is the eutectoid of corundum and zirconium clinite, and glass phase is filled between their crystals.
Fused zirconium corundum brick AZS33# :
The compact microstructure of AZS33# zirconium corundum brick makes the brick have good resistance to glass liquid erosion, and it is not easy to produce stones or other defects in glass kiln. It is a widely used product in glass kiln, mainly suitable for the upper structure of the melting pool, the pool wall brick and paving brick of the working pool, the feed road and so on.
AZS33 is a widely used and widely used product in the AZS series of products, which has superior performance in preventing contamination of glass liquid. It is widely used in the pool wall, the bottom of the pool, the upper structure and the feeding channel of the glass kiln.
Fused zirconium corundum brick AZS36# :
In addition to having the same cocrystallization as AZS33# fused zirconium corundum brick, 36#AZS brick has further enhanced the corrosion resistance of 36# fused zirconium corundum brick due to the increase of more chain-like zirconia crystals and the lower glass phase content, so it is suitable for areas where the glass liquid flow rate is faster or the temperature is higher.
AZS36 is an excellent product in the AZS series of fusible casting products, with high resistance to glass corrosion and low pollution characteristics, and is usually used in key parts such as the pool wall near the hot spot of the melting pool in the glass furnace.
Fused zirconium corundum brick AZS41# :
AZS41# fused zirconium corundum brick in addition to silicon oxide, alumina eutectic, but also contains more uniform distribution
