The application of High alumina brick
High alumina brick is a kind of refractory material. The main component of this refractory brick is AL2O3. If the Al2O3 content is higher than 90%, it is called corundum brick. A neutral refractory with an alumina content of more than 48%. It is made from bauxite or other raw materials with high alumina content through molding and calcination. High thermal stability, fire resistance above 1770 ℃. Good slag resistance, used for lining of steelmaking electric furnace, glass melting furnace, cement rotary furnace, etc. High-load soft, low-creep high-alumina brick is a high-grade refractory made of super-alumina, fused alumina, and fused mullite. This product has the advantages of small creep at high temperature, strong erosion resistance and good thermal shock stability.
