Second Hand Used AZS Refractory Brick for Glass Furnace
Fused Cast AZS are the most widely used materials in glass melting
furnaces, frit kilns and occasionally some foundry plants(skid
rails of reheating furnace). They can be classified by their
zirconia content, which basically defines their corrosion
resistance, into 3 families: AZS 33, AZS36 &AZS 41 
AZS 33: The compact microstructure of AZS 33 enables it to have
very good corrosion resistance to molten glass. It very rearely
results in stoning and has very limited chances to cause blistering
and othe defects to glass, so AZS 33 is the most common product
used in the glass furnace.
AZS 36: Despite of the similar eutectic crystal as AZS 33, AZS 36
has more free baddeleyite crystals in chain structure and less
vitreous phase, which further improve the corrosion resistibility
and reduce the potential defects in glass, so it is recommended to
be used in sections where glass flow is faster and temperature is
higher, such as melter sidewall, paving, doghouse, etc.
AZS 41: AZS 41 has the most free baddeleyite crystals among the
fused cast AZS families, which are evenly distgributed within the
block. Its corrosion resistibility is the best and thus it is
usually recommended to be used in the most demanding positions to
balance the furnace life.
Futures of High Temperature Resistance of AZS Refractory Brick for Glass Furnace:
1.Casted by melting raw material in the mold, then cooling and solidification.
2.Strong glass corrosion resistance and high thermal shock stability.
3.Good wear-resistance,drags-resistance and alkali corrosion resistance.
4.High-purity raw material, less pollution.
5.Top quality, long service time.
