Magnesia alumina spinel brick

Magnesia alumina spinel bricks were developed by Chinese scientists based on natural resources in China and we have a lot of alumina in China. The main crystallization of magnesia alumina brick is perispar and magnesia alumina spinel is its matrix. The raw materials are magnesite and industrial alumina

Advantages

  Magnesium aluminum spinel is made of high quality bauxite with more than 76% Al2O3 content and high quality light fired magnesium powder with more than 95% MgO content. After multistage homogenization process, it is sintered at high temperature above 1800°C in ultra-high temperature tunnel kiln. It has large volume density, high mineral phase content, good grain development, uniform structure and stable quality. Magnesium aluminum spinel has good corrosion resistance, corrosion, peeling ability, good slag resistance, abrasion resistance, good thermal shock stability, high temperature resistance and other performance characteristics.

  Application

The main uses of magnesia alumina spinel: one is to replace magnesia chromium sand to manufacture magnesia aluminum spinel brick for cement rotary kiln, not only to avoid chromium pollution, but also has good spalling resistance; Second, it is used to make ladle castable, which greatly improves the anti-erosion ability of steel lining. Make it widely used in steel refractory materials. The preparation of high quality pre-synthetic spinel provides a new raw material for the production of amorphous and amorphous high purity refractories.
