Magnesia-Alumina Spinel Brick is in order to improve the heat stability of magnesia brick, add alumina oxide in ingredient to generate the magnesia brick which the main material is magnesia-alumina spinel. The advantage of magnesia-alumina spinel brick: good heat stability, in the process of use, it will have reaction with clinker and produce a thin layer of calcium aluminate maskant, which makes the liquid not easy to penetrate, its anti-stripping performance is better than the direct bonded magnesia chrome brick.
Application of Magnesia Alumina Spinel Brick
1.The
magnesia-alumina spinel can be used in the cement
kiln, not only avoid the chrome pollution, and has
good anti-stripping performance. 2.It can be used in
refractory carstables for ladles, which greatly
improve the anti-erosion ability. It is widely
applied to steel-making refractory material. The
preparation of high quality pre-synthertic spinel
provide a new material for amorphous and fixed high
purity refractory.
