Mg-Al Brick is an alkaline refractory made from magnesia and a small amount of industrial alumina or bauxite. The thermal stability is better than that of magnesia bricks, and the refractoriness is above 1580 C. Corrosion resistance to alkali resistant slag. Mainly used in open hearth furnace and electric furnace roof, high temperature tunnel kiln, large cement rotary kiln and non-ferrous metal smelting furnace.
Mg-Al Brick is mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal melting, and so on．
P.S.: The size and shape of the brick can be produced as required.
