High alumina brick Alumina brick manufacturer Alumina brick for industry furnaces such as Blast furnace, hot-blast furnace and EAF etc. For High alumina brick the temperature of refractoriness under load is normally above 1420~1550C that is higher than the fireclay brick and it increases along with the AL2O3 content enhances.
For High alumina brick the thermal Shock resistance is mainly decided by chemical contents 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.
High alumina brick are used normally in industry furnaces such as Blast furnace, hot-blast furnace and EAF etc.
