Fire Resistant Kiln Refractory Zircon Mullite Brick For

Fire Resistant Kiln Refractory Zircon Mullite Brick For Cement Kiln And Hot-blast Stove

Quick Detail:

1, High strength
2, Good thermal shock resistance
3, High temperature erosion resistance
4, Good slag resistance

Description:

Zircon mullite brick selected high quality mullite sand and zircon powder as its main raw material. Molded by high pressure and sintered by high temperature , the zircon-mullite brick has such advantages as high bulk density, high strength, good thermal shock resistance, high temperature erosion resistance and good slag resistance. It is mainly used in long-life orifice rings, tank bottom, tank superstructure, perfume-bottle feeder, covers for working tanks and soda lime glass.

Applications:
The zircon mullite brick is mainly used in long-life orifice rings, tank bottom, tank superstructure, isostatically pressed, electrode blocks, perfume-bottle feeder, covers for working tanks and soda lime glass, etc.
