Product Description
Product Description of Refractory Al2o3 Furnace Door Block High Alumina Refractory Brick for Kiln With Low Apparent Porosity
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.
