Iron and Steel Slag Statistics and Information

Iron and Steel Slag Statistics and Information

+

Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and ...
