Zircon corundum brick isalso named AZS brick( alumina zircon silica ),according to the ZrO2 content
difference ,can be named AZS 5.5 ,AZS 12 .AZS 36, AZS 33, AZS 41 and so on. Beside because
this type bricks are produced by special electric furnace by model, we also called this products
Fused cast AZS bricks.
These bricks are widely used for iron & steel furnace and glass furnace, also chemical industrial
furnace, especial in the glass furnace, you will find it usually.
