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.
