Using high pure light burned magnesia and alumina production in large smelting furnace of spinel, has the characteristics of large volume density, good luster, strong corrosion resistance, good thermal stability, widely used in steelmaking EAF roof, converter and electric furnace ladle, non-ferrous smelting furnace, cement industry transition zone of rotary kiln and glass melting kiln regenerator etc.. According to the needs of the user can be divided into three kinds of alumina content of 70%, 85%, 90% different spinel clinker and spinel solid solution, according to user needs processing a variety of specifications for products.
