Recycling and environmental issues of metallurgical slags

their separation from the iron or steel, or later by re-melting in a separate furnace. Blast Furnace (BF) slags BF slag is formed in the reduction process from iron ore, coke, limestone etc. at temperature range from 1450 to 1550°C, thus contains lower iron oxides and is tapped off from time to time. The chemical compositions of the slag depend on the feeding raw materials and, smelting

Properties and Uses of Steelmaking Slag IspatGuru

14/11/2018· Steelmaking slag contains around 10 % of scrap which comes from the refining process or from some of the processing vessel (e.g. BOF, EAF, steel teeming ladle, or tundish). It is advantageous to separate this scrap from the slag for the purpose of recycling the recovered scrap in the primary steelmaking process for making the slag free from scrap for its various applications. Hence, after

Iron and Steel Slag Statistics and Information USGS

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 are formed. The physical characteristics

04/04/2012· D. Sichen, in Fundamentals of Metallurgy, 2005 9.5.1 Slag–metal mixing. In steelmaking, slag–metal mixing is a very common phenomenon and it occurs due to the shear at the slag–metal interface caused by excessive liquid steel flow. 37 This mixing leads to emulsification of steel in slag, which increases the total interfacial area and consequently the rate of slag–metal reactions.

Iron and steel industry in the United States Wikipedia

In an integrated steel mill, iron ore is reduced to metallic iron. Slag, a byproduct of iron and steel-making composed primarily of highly impure glass, would normally be a waste product. However, it is in demand as an aggregate in concrete, asphalt paving, and construction fill. In 2014, the industry produced and marketed about 16.0 million mt of slag, worth an estimated $270 million
