A neutral refractory material with an alumina content of over 48%. Made from raw materials with high alumina content, such as bauxite, through molding and calcination. High thermal stability, with a fire resistance of over 1770 ℃. Good slag resistance, used for lining steel furnaces, glass melting furnaces, cement rotary furnaces, etc.

Feature:
1.High refractory temperature and load softening temperature.
2.Acid resistant solution or slag with strong corrosiveness.
3.Excellent heat shock resistance and wear resistance.
4.High compressive strength at room temperature.
5.Accurate specifications and dimensions, capable of processing various sizes according to drawings.

Usage:

High alumina bricks are mainly used for lining blast furnaces, hot blast stoves, electric furnace tops, blast furnaces, reverberatory furnaces, and rotary kilns. In addition, high alumina bricks are widely used as regenerative grid bricks for open hearth furnaces, plugs for pouring systems, water inlet bricks, etc.
