Magnesia Iron aluminum spinel brick

Magnesia Iron aluminum spinel brick not only has a good performance of thermal shock resistance and dense skin hanging, but also has a relatively low price, low thermal expansion and conductivity, which will not cause the shell to deform due to overheating, resulting in energy loss. Therefore, it has been widely used in the modern dense atmosphere stable cement rotary kiln firing belt. In addition, the structure flexibility of Magnesia Iron aluminum spinel brick is also excellent, which can effectively prolong the service life of the material. It can react with cement clinker to generate compounds. At the same time, the diffusion of Fe2O3 component makes the reaction site further expanded, which makes the stability of kiln skin better. At the same time, the bonding structure of the brick tends to be developed due to the effect of Fe2O3, which makes the adhesion and anti peeling of the kiln skin significantly improved. However, the disadvantages of MgFe al spinel brick lie in its poor performance of oxidation resistance, reduction resistance, corrosion resistance and high temperature resistance, which restricts its application and development to a certain extent
