Descrition:
Insulating Firebrick / Mullite Brick/ High alumina brick with light weight has high mini-porosity
arranged in average, keep furnace wall low radiation.They can be
used for hot face lining directly exposed to the heat or as a
backup insulation layer.Light weight means the lowest thermal
storage, it's quicker to heat and cool, and permit rapid cycle
work.They are used for 800C~1500C
#Property
Light weight and low thermal conductivity reduce the thickness of
the insulating layer
Maintain stable structural strength throughout ambient to maximum
service temperature
Low heat storage results in rapid cooling and heating operation
Low iron and impurities to enhance reducing atmosphere;
High thermal shock resistance in preventing spalling;
Customize any size and shape
High spalling resistance
High hot compressive strength
Accurate dimensions
Roller kiln
