  • Slags Ferrous Metal Blast Furnace Registration Dossier

    EC number: cas number: the fused substance formed by the action of a flux upon the gangue of the iron-bearing materials charged to a blast furnace and upon the oxidized impurities in the iron produced. depending upon the particular blast furnace operation, the slag is composed primarily of sulfur and oxides of aluminum, calcium, magnesium, and silicon.simultaneously with iron in a blast furnace. agricultural values of blast furnace slag are generally believed to be a liming material because of its calcium and magnesium content and a potential source of minor or trace elements. farmers in ohio are requesting information as to the crop-produc ing value of blast furnace slag and the
