High Alumina Bricks Refractories In Steel Making GL-70
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 brick, High alumina brick have very good ability of anti-acidity, anti-metal fluid corrode and anti-oxidation.
