Sintered Zirconia Corundum Brick

Sintered zirconium corundum brick (AZS brick for short) refers to a refractory product with a ZrO₂ content of 33%-45% made from industrial alumina powder and selected zircon sand. The main raw materials are industrial alumina calcined into α-Al₂O₃, partially stabilized zirconium dioxide, and zirconium corundum clinker fine powder. The raw materials are mixed, high-pressure molded, dried, and then fired at 1700-1750℃ according to a certain ratio.

The raw materials are mixed, high-pressure molded, dried, and then fired at 1700-1750℃ according to a certain ratio.

Characteristics of Sintered Zirconium Corundum Brick

 

  • Strong erosion resistance
  • High density and low porosity
  • Excellent thermal shock resistance
  • High structural strength at high temperatures

Application of Sintered Zirconium Corundum Brick

  • Glass industry: It is the preferred material for core parts such as the pool wall, flow hole, charging port, and bubbling area of glass melting furnace.
  • Metallurgical industry: It is used for slag line in ladle refining area, RH/OBS vacuum refining furnace immersion tube, heating furnace slide rail and other parts.
  • Chemical industry: It can be used as the core lining of ethylene cracking furnace, coal gasification furnace, carbon black reaction furnace and other high-temperature and complex chemical corrosion environments.
  • Ceramic industry: It is used in the key high-temperature zone of ultra-high temperature tunnel kiln and shuttle kiln for firing advanced ceramics and refractory materials.
