Product overview
The compact micro-structure of Fused cast AZS 33 brick enables it to have very good corrosion resistance to molten glass. It has very small possibility to cause blistering and very rarely results in stoning and other defects to glass, So Fused cast AZS 33 brick is the most widely used AZS product in the glass furnace and is superior in preventing pollution to the molten glass. It is suitable material for superstructure, sidewall, paving and feeder,etc.
Character:
Good corrosion resistance , small possibility to cause blistering, stoning and other defects to glass, preventing pollution to the molten glass.
