Glass Furnace Application Fire Resistant Mullite-sillimanite Brick
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.
