High Aluminum Brick

  • Product Description:

    High alumina brick is made of alumina, fused alumina, fused mullite as the main raw materials of shaped refractory products, the main component is Al2O3.
  • Product Features:

    High alumina brick products have the advantages of small temperature creep, strong corrosion resistance and good thermal shock stability.
  • Application:

    High alumina brick is mainly used for lining of blast furnace, hot blast furnace, electric furnace roof, reverberatory furnace and rotary kiln. In addition, high alumina brick also widely used as open hearth regenerative lattice brick, pouring system with plug, such as nozzle brick.
