Product Description
Product Description
Magnesium aluminum spinel brick Introduce
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. High quality pre-synthetic spinel is made of amorphous and shaped high purity refractory.
Features of Magnesia Alumina Spinel Brick
1. Good thermal stability
In the course of the use of clinker with the reaction, the brick surface forms a thin layer of calcium aluminate protective layer, so that the liquid is not easy to penetrate.
2. Good anti-peeling performance
Magnesium aluminum spinel brick is better than the direct combination magnesia-chrome brick at anti-peeling performance. The life of the cooling zone and the transition zone of the kiln can be directly combined with magnesia-chrome brick. However, the corrosion resistance is slightly inferior to the direct combination magnesia-chrome brick.
3. Good heat resistance
Sintered spinel brick is easy to hydrate, resulting in larger coefficient. The kiln body temperature is higher than the direct combination magnesium chrome brick.
4. Anti-quenching and emergency hot
5. Good corrosion resistance
Magnesium aluminum spinel brick has good corrosion resistance to iron oxide, alkaline slag and other solvents.
Applications
Magnesium aluminum spinel brick is widely used in cement rotary kiln, but also for the production of ladle castable material, greatly improve the corrosion resistance of steel lining, making it widely used in steel refractories. High quality pre-synthetic spinel is made of amorphous and shaped high purity refractory.
