Magnesia alumina spinel brick is a kind of general refractory bricks which is manufactured by using magnesia sand and little industrial alumina oxide or bauxite as raw materials. The thermal shock resistance of magnesia alumina spinel brick is better than magnesia bricks, and the refractoriness is above 1580°C, 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 cement kiln, large-scale cement rotary kiln and non-ferrous metal smelting furnaces, etc.
