Fire Resistant Kiln Refractory Zircon Mullite Brick For Cement Kiln And Hot-blast Stove
Properties of Zircon Mullite Brick
1, High strength
2, Good thermal shock resistance
3, High temperature erosion resistance
4, Good slag resistance
Description of Zircon Mullite Brick
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 of Zircon Mullite Brick
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.
