High Alumina Refractory Bricks Description
The high alumina brick is an alumina-silicate refractory material in which the Al2O3 content is more than 55%, and is calcined from a high-content alumina raw material such as a silicone raw material or a bauxite. High heat resistance and high temperature resistance at 1770°C and above. Has good slag resistance, mainly used in the masonry of steelmaking electric furnace, glass furnace, cement rotary furnace and so on.
High Alumina Refractory Bricks Features:
1. Low bulk density, low thermal conductivity, good thermal performance.
2. Refractory category allow direct contact of fire, suitable for various atmosphere
3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely
High Alumina Refractory Bricks Typical Applications:
1. Furnaces of metallurgy industry, heat treatment furnace
2. Furnaces of chemical industry and construction industry.
3. Furnace of incineration of garbage, recirculating fluidized bed furnace
