Steel Slag Of The Steel Mill

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

    Steel mill slags energy potential: the case of the steel

    Feb 08, 2012 Slag accounts for most of the residuals or by-products of the steel manufacturing process and represents a not inconsiderable amount of energy waste and CO 2 emissions. Energy recovery from steel mill slags is not actually performed because of the difficulty of the industrial implementation, but the actual demand and the incentives for new electricity generation plants based

    Once viewed as a waste product, steel mill slag is now generally engineered to be useful by-products. Principal uses of slag include concrete and asphalt aggregates. It is also extensively utilized for placement of highway shoulder berms, driveway and parking lot fills, stream bank protection, and as railroad grade ballast. Slag has been used

    Steelmaking slag (BOF and EAF) is cooled similarly to air-cooled BF slag and is used for most of the same purposes. As the production process varies at this stage, depending on the type of steel being made, the resulting slag also has diverse chemical properties making it more difficult to use than ironmaking slag. Some of the recovered slag is
