The production of steel in an EAF is a batch process. Cycles, or "heats", range from about 11/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and slag materials are added for refining. Stages
Steel slag is the main waste product in the steelmaking process. Because of its chemical composition and technical properties, it can be reused as raw material in steel plants and can serve as a ...
Ferrous slag is the byproduct of iron and steel manufacturing. It arises from the conversion of ores to iron, hot iron to steel, from melting scrap in an electric arc furnace or from the subsequent treatment of crude steel. Each year, about 45 million tonnes of ferrous slag (iron and steel slag.
Mar 01, 2007· The chemical composition of typical LD slag samples generated at steel plant is shown in Table 5. The main components are Fe, CaO, and SiO 2. The high content of CaO in the slag can be used to substitute for a part of limestone as fluxing material to reduce the iron in steel making cost.
Slags are nonmetallic byproducts of many metallurgical operations and consist primarily of calcium, magnesium, and aluminum silicates in various combinations. 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
