Features For Corundum Fire Brick:

 

1. Raw material is corundum and baddeleyite eutecticum,high compression strength

 

2. Top high-temperature capablility.

 

3. Excellent thermal stability.

 

4. Low thermal conductivity

 

5. Powerful penetrating-proof capability.

 

6. Good erosion-resistance.

 

7. Strong resistant erosion stability to the glass liquid

 

 

Process For Corundum Fire Brick :

 

Made of the zirconite (Industry zirconia ) and industry alumina as the mainly mixed raw material, melting in the electric furnace, casting, annealing, machining, then finished.
