ISO certified fused magnesia alumina spinel kiln refractory brick for cement kilns
Magnesium aluminum spinel brick is to improve the thermal stability of magnesium bricks, adding alumina in the ingredients and the production of magnesium aluminum spinel as the main mineral magnesium brick. Magnesium aluminum spinel brick is a low calcium content of high quality magnesia and industrial alumina powder as the main raw material, by high pressure forming, high temperature firing. Anti-quenching and emergency hot, good for iron oxides, alkaline slag and other solvents have good resistance to erosion.
Advantages
Good thermal stability, in the course of the use of clinker with the reaction, and then in the brick surface to form a thin layer of calcium aluminate protective layer, so that the liquid is not easy to penetrate.
its anti-peeling performance is better than the direct combination of magnesia-chrome brick. The life of the cooling zone and the transition zone of the kiln can be directly combined with magnesia-chrome brick. However, in the corrosion resistance is slightly inferior to the direct combination of magnesia-chrome brick.
Sintered spinel brick easy to hydrate, resulting in a larger coefficient, the kiln body temperature than the direct combination of magnesium chrome brick when the high. In the use of attention to these issues.
