Jul 07, 2017· Limestone – Its Processing and Application in Iron and Steel Industry. Limestone is a naturally occurring and abundant sedimentary rock consisting of high levels of calcium carbonate (CaCO3) in the form of the mineral calcite. Some limestones may contain small percentage of magnesium carbonate (MgCO3).
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.
Basic Oxygen Furnace Steel Slag (BOF or Steel Furnace Slag) This slag Is formed when molten Iron, scrap metals and various fluxes, such as lime, are oxidized by injecting large amounts of pure oxygen into the molten iron mix to create molten steel and molten slag. Slow cooling of the molten slag produces a dense rock material. Principal uses ...
