High Alumina Bricks are a kind of commonly used refractory materials for sale in RS Company, which is mainly made of Al2O3. High Alumina Brick has properties of high refractoriness, high strength, acid and washing erosion resistance, good thermal stability and so on. High Alumina Bricks are widely used in industries of blast furnace, hot blast stove, electric furnace, refining furnace and glass furnace and so on.
Alumina Bricks are alumina-silicate refractory with more than 48% Al2O3 content. High Alumina Bricks are manufactured with alumina or other raw materials containing higher alumina content through molding and firing. High Alumina Brick can resist acid slag erosion resistance because of its neutral refractory property. High Alumina Bricks have high thermal stability and refractoriness over 1770℃.
