Standards for High-Alumina Refractory Bricks

  1. High-alumina bricks are a kind of refractory material. The main component of this refractory brick is AL2O3.
  2.  A neutral refractory material with an alumina content of more than 48%. It is formed and calcined from bauxite or other raw materials with high alumina content. High thermal stability, refractoriness above 1770°C. It has good slag resistance and is used for lining steel-making electric furnaces, glass melting furnaces, cement rotary furnaces, etc.
  3.  High-load, soft, low-creep high-alumina brick [1] is a high-grade refractory material made of special grade bauxite, fused corundum, and fused mullite as the main raw materials. This product has the advantages of small high-temperature creep, strong corrosion resistance, and good thermal shock stability. It is suitable for large and medium-sized hot blast stove
