Alumina Refractory Bricks Introduction
1. Alumina Refractory Bricks is a kind of refractory material with high refractoriness.
2. Al2O3 Content of fire clay refractory brick : 30% above.
3. Refractoriness of fire clay refractory brick is normally above 1580℃, and will increases along with the Al2O3 content.
Alumina Refractory Bricks Features
1. Low bulk density, low thermal conductivity, good thermal insulation performance.
2. Refractory category allow direct contact of fire, suitable ofr various atmosphere
3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely
