Product Description
Brief Introduction of High Alumina Refractory Brick for Steel Furnace With 48-80% Al2O3 Refractory Fire Bricks For Sale
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 1770℃. Good slag resistance, used for the liner of masonry steel-making electric stove, glass furnace and cement revolver.
Features of High Alumina Refractory Brick for Steel Furnace With 48-80% Al2O3
