  Magnesia alumina brick is a kind of basic refractory material which is manufactured by using magnesia and little industrial alumina oxide or bauxite as raw materials. The thermal shock resistance of magnesia alumina brick is better than that of magnesia bricks, and the refractoriness is above 1580℃, with high corrosion resistance to basic melting slag. It is mainly applied to the top of steel making open-hearth furnace and EAF, high temperature tunnel kiln, large-scale cement rotary kiln and non-ferrous metal smelting furnaces, etc.
