High Grade High Purity Corundum Bricks for Industry Furnace and Kilns
Features For Corundum 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 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.
