Magnesium Aluminum Spinel Brick(RC)
Magnesium Aluminum Spinel Brick(RC) /Excellent fire resistance/Excellent thermal shock resistance/Excellent resistance to sulfur alkali salt chemical erosion
Summary:
Magnesium aluminum spinel brick RC has been developed for use in the upper and lower transition zones of cement rotary kilns with unstable kiln skins. It can also be considered for use when the kiln skin is unstable during firing. This economical product has excellent performance and its cost-effectiveness is highly attractive to our customers. Thanks to the purity of sintered magnesium oxide and magnesium aluminum spinel, this refractory brick repels the kiln skin, highlighting its advantages in areas where the kiln skin is constantly changing. Due to the low impurity content in the raw materials, this refractory brick also has high resistance to chemical corrosion by sulfur alkali salts.
