When the temperature fluctuates, the expansion and contraction of magnesia alumina spinel brick are relatively uniform, the thermal shock stability is good, and the load softening temperature and strength are better than magnesia brick. The ability of magnesia alumina spinel brick to resist alkaline slag and iron oxide slag is stronger than magnesia 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.
