Features for AZS33#,AZS26#,AZS41# brick
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.
2)Features for AZS36# brick
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.
3)Features for AZS41# brick
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.
Size for fused cast zirconia corundum brick
Both can make brick according to customers’ drawing and requirements.
Application for fused cast zirconia corundum brick
AZS 33# brick is the most common product used in the glass furnace.
AZS36# brick is used in sections where glass flow is faster and temperature is higher,such as melter sidewall,paving,dog-house.
AZS41# brick is used in quick wear positions to balance the furnace life.
