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.
