CCEFIRE ® DECOR Series Corundum Brick

Product description

Corundum brick is a kind of high aluminum brick that is used in special industries. Al2O3 content can be traced back to using high purity synthetic corundum like white melted AL2O3 and sliced Al2O3. Special refractory clay, activated aluminum oxide and high purity SiO2 are all included in formula of producing corundum brick. We fire bricks under high temperature.

Features and Application

Characteristics:

  • High compressive strength at room temperature;
  • High load softening temperature greater than 1700ºC ;
  • Good chemical stability;
  • Good acid or alkaline slag resistant;
  • Strong metal and glass resistant.

Application:

Mainly used for blast furnace and blast furnace hot stove, steel refining furnace, glass melting furnace and petrochemical industry furnace.

Advantage

  1. Corundum bricks are refractory products with corundum as main crystal phase and alumina content is more than 90%.
  2. There is the relationship between the thermal shock stability and its organizational structure. Dense products have good corrosion resistance but the thermal shock stability is poor.
  3. There are sintered corundum bricks and fused corundum bricks.
  4. By using sintered alumina and fused corundum as the raw material respectively or coordinate with high rate content of Al2O3 / SiO2 bauxite clinker and sintering alumina, made by sintering method.
  5. Phosphoric acid and other binder can also be used to make un-sintered brick.
