High Alumina Refractory Brick Introduction
High alumina brick is a kind of alumina-silicate refractory material with content of alumina oxide more than 48%. 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 1770ºC. Good slag resistance, used for the liner of masonry steel-making electric stove, glass furnace and cement revolver.
