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 ...Iron and steel slags are coproducts of iron and steel manufacturing.

Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded.Dec 27, 2015 Ferrous slag forms as a dominantly calcium silicate melt that floats on top of the molten crude iron or steel the slag is then removed from the liquid metal. For typical iron ore grades 60 to 66 percent iron, blast furnace slag output will be about 0.25 to 0.30 metric tons of slag per ton of crude ironBlast furnace slag is a combination of silica and other non-ferrous components of iron ore, ash from coke used as a reducing material, and limestone auxiliary material. Because its specific gravity is less than that of pig iron, during the heating process the molten slag rises above the pig iron allowing it to be easily separated and recovered.
