High grade bauxite insulating firebrick / High Alumina Refractory Brick For Furnace
Introduction of high alumina brick
High alumina brick is made by high grade bauxite, with unique advanced technology, the temperature of refractoriness under load is normally above 1420~1550°C , which is higher than the fireclay brick and it increases along with the AL2O3 content enhances.
Characteristices of high alumina brick
1. High intensity for pressure
2. Good thermal shock stability
3. Strong abrasion and corrosion resistance
4. High cold crushing strength
5. Excellent abrasion resistance at cold and hot conditions
Application of high alumina brick
1. Steel furnaces
2. Iron making furnaces
3. Glass kiln
4. Ceramic tunnel kiln
5. Cement kiln
