Magnesium Aluminum Spinel Brick(R2)

Summary:

Like the magnesia alumina spinel brick R1, R2 is also made of high-purity sintered magnesia. In contrast to R1, R2 is added with prefabricated fused magnesia alumina spinel, which has the characteristic of repelling kiln skin and is specially developed for areas with frequent aging and thermal shock of kiln skin. In addition, R2 has high resistance to alkali salt and sulfur corrosion, and is a product developed for rotary kilns with harsh working conditions.

Product features:

  • 1. Excellent fire resistance
  • 2. Excellent thermal shock resistance
  • 3. Excellent alkali salt corrosion resistance

Range of application:

Cement Kiln (Severe chemical/thermal load) Upper Transition Zone,

Lower Transition Zone,Outlet Zone;
