Refractory Mullite Brick for Hot Blast Stove
The mullite insulating brick which is produced by synthetic mullite sand and polystyrene sphere has better performance than clay insulating brick and high alumina insulating brick.
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.
