Mullite Insulation Brick Refractory Brick
1) Mullite Insulation Brick is manufactured from high-grade refractory powder and materials in good purity, compressed in vacuum and sintered under high temperature.
It covers six temperature classes: 1300C, 1400C, 1500C, 1550C, 1600C, includes standard brick, special-shaped brick, and refractory mortar.
2)Used in various of industrial furnaces, such as metallurgy, construction, ceramic, machinery etc, for liner and backing,
such as cracking furnace, reforming furnace, heating equipment,
refining equipment, hot blast stove, heating furnace, soaking pit,
thermal treatment furnace, resistance furnace, tunnel kiln, roller kiln,
shuttle kiln, immersion bell, glass furnace etc.
