High Alumina Brick Introduction
High alumina brick is a kind of alumina-silicate refractory material with content of alumina oxide more than 48% Al2O3. It is calcined and formed by the raw material of banxite or the material with high content of AL2O3. High thermal stability, the refractoriness is more than 1770℃. Good slag resistance, used for the liner of masonry steel-making electric stove, glass furnace and cement revolver.
The properties of high alumina bricks
- High alumina bricks have higher refractoriness reaching up to 1750~1790℃ , which is higher than fire clay brick, etc.
- High Alumina Bricks have higher refractoriness under load owing to the higher Al2O3 content and low impurities.
- Resistance to Slag, it can resist to the acid and basic slag erosion.
Use of High Alumina Brick
So according to the properties of the high alumina bricks, high alumina brick can be used in blast furnace, hot blast stove, electric furnace roof, blast furnace, reverberatory furnace, lining of rotary kiln. In addition, the high alumina brick is widely used in checker bricks of heat accumulating type, chock plug for gating system, nozzle brick and so on.
