Description
zircon corundum refractory brick for steel furnace

AZS 33 brick

Feature:
1.Have very good corrosion resistance to molten glass.
2.It very rarely results in stoning and has very limited chances to cause blistering and other defects to glass.
Application:
AZS 33 refractory brick is the most common product used in the glass furnace.















AZS 36 brick
Feature:

1.Have more free baddeleyite crystals in chain structure and less vitreous phase 
2.Further improve the corrosion resistibility and reduce the potentical defects in glass.
Application:
It is recommended to be used in sections where glass flow is faster and temperature is higher,such as melter sidewall paving dog house etc.
 



AZS 41 brick

Feature:
1.Have the most free baddeleyite crystals among the electro-fused Al2O3-ZrO2-SiO2 series products,which are evenly distributed within block.
2.Have the best corrosion resistibility.

Application:
It is usually recommended to be used in quick wear positions to balance the furnace life.
