Production process
Professional production of corundum mullite bricks
Oxidation melting casting AZS41
AZS-41# Zirconium corundum brick contains more uniformly distributed aluminum oxide crystals, and its erosion resistance is the best in the zirconium corundum series. Therefore, it is selected for the key parts of the glass furnace so that the life of these parts can be balanced with the life of other parts.
