Description

 High alumina bricks for general uses are mainly made from super quality Bauxite, bonding chamotte and additives, being high pressure pressed and sintered in high temperature.

 

Brick refractory features and advantages:

  • The dimensions are more exactly.
  • Low iron content and impurities
  • Good thermal stability
  • High refractoriness
  • anti alkaline /acid erosions,
  • Mechanical and chemical properties are very good.
  • Strong thermal shock resistance.
Application

Brick refractory is widely used in all parts of furnace lining of metallurgic, petroleum, construction materials, machinery and militaries, etc.
