High alumina anchor bricks are made of natural high-grade bauxite as the main refractory raw material, adding soft or semi-soft clay as a binder to the high-alumina clinker to start batching, mixing, molding, drying, and finally firing. Shaped high alumina refractory bricks.


  1. High temperature volume stability.
  2. Good corrosion resistance.
  3. High softening temperature under load.
  4. Anti-peeling, high compressive strength.
