Furnace Refractory
Al2O3 65% High Alumina Refractory Bricks 1470°C Alumina Firebrick Fe2O3 2.5%
High Alumina Brick GL-65: Refractoriness >1470℃, Al2O3 ≥65%, Fe2O3 ≤2.5% High Alumina Brick Features: High alumina brick the temperature of refractoriness under load is normally above 1420 ~1600 ℃ that is higher than the fireclay brick and it increases along with the Al2O3 content enhances. For the high alumina brick the thermal shock resistance is mainly decided by chemical content and its mineral microstructure but its thermal shock resistant is worse than the fireclay
JM30 Mullite Insulation Brick Low Thermal Conductivity Mullite Insulating Brick
Mullite Insulation Brick with Low Thermal Conductivity JM30 Mullite Insulation brick Mullite insulation bricks have high refractoriness, can directly contact the flame, and have the characteristics of light weight, high strength, low thermal conductivity, good thermal shock resistance and remarkable energy saving effect.
