Magnesia Chrome Bricks

Magnesia chrome bricks

Magnesia chrome bricks are made from high quality magnesia and chrome concentrate, cr2o3 content can be adjusted according to different requirements. Cr2O3 can increase the refractory bricks erosion resistance ability to mirabilite (salt cake)


1-Outstanding ability to form stable protective coating

2-High flexibility

3-High refractoriness

4-Low thermal conductivity


1-Used for the roof to all kinds of steelmaking furnace.

  1. RH, VOD, AOD, and other refining installations.
  2. Building industry, glass furnace, cement rotary kiln etc.
