Fireclay Refractory Fire Bricks

We offer high quality fire clay refractory bricks with competitive prices.

Fire Clay Brick is most used refractory brick in the iron & steel industry, glass industry, non-ferrous industry, cement industry, pottery kilns and many other industries with the advantages of its lower cost. Typical composition of Fire Clay Bricks consists of SiO2 < 78% and Al2O3 < 44%.

 

Low Duty Fireclay Bricks

Low Duty Fire Clay Bricks are mainly used for fireplace, chimneys, and also used as back up bricks for bricks with higher refractoriness.

  • SiO2 Content 60%-70%
  • Al2O3 Content 23%-33%
  • Other Contens 6%-10%
  • Working Temperature 1500 °C - 1590 °C
 

Medium Duty Fireclay Bricks

Medium duty fireclay bricks are suitable for use in applications unde the conditions of moderate severity. They are mostly used as backup linings, and also for lower-temperature ceramic kilns and chimneys.

  • SiO2 Content 60%-70%
  • Al2O3 Content 26%-36%
  • Other Contens 5%-9%
  • Working Temperature 1630 °C - 1690 °C
 

High Duty Fireclay Bricks

High duty fireclay bricks are used in a wide range of applications such as boilers, ceramic kilns, chimneys and back-up linings. They have good resistance to thermal shock, so fireclay bricks are more economic to use for lining of furnaces over long periods of time.

  • SiO2 Content 55%-60%
  • Al2O3 Content 35%-40%
  • Other Contens 5%-9%
  • Working Temperature 1690 °C - 1740 °C
 

Super Duty Fireclay Bricks

These bricks have good strength, refractoriness, volume stability at high temperatures, superior resistance to cracking or spalling during rapid changes of temperature.

  • SiO2 Content 49%-53%
  • Al2O3 Content 40%-44%
  • Other Contens 5%-7%
  • Working Temperature 1740 °C - 1760 °C
