Fused AZS bricks are indispensable refractory material for glass kiln key parts, because they not only have strong resistance to glass liquid corrosion, but have no pollution to glass liquid. AZS bricks are all called zirconia corundum bricks. The primary raw materials of fused AZS bricks are industrial alumina, ZrO2 and calcined zircon, auxiliary materials are sodium carbonate and borax. Fused AZS bricks production process is: raw material batching-three-phase electric arc melting-casting-annealing-machining and inspection. By ZrO2 content, fused AZS bricks are divided into fused AZS-33 bricks, fused AZS-36 bricks and fused AZS-41 bricks.


Advantages of Glass Furnace AZS Refractory Bricks
High refractoriness and high refractoriness under load.
Good resistance to glass liquid corrosion.
Good thermal stability.
Wearing resistant and washing-out resistant.
Long service life.

The Application of AZS Bricks
The most important application of AZS bricks is glass furnace. AZS-33 bricks are mainly used at working tank, fore-hearth, upper structure and crown. AZS-36 bricks have high corrosion resistance and low pollution to glass liquid, they are mainly used at the parts contacting with glass liquid, such as melting tank wall, clarification tank, working tank and so on. AZS-41 bricks have the best glass liquid corrosion resistance and the lowest pollution to glass liquid. Their main application parts are: melting tank wall, throat, kiln weir, charging hole corner brick, bubble bricks, electrode bricks and so on.
