steps in the modern steelmaking process
D. Sichen, in Fundamentals of Metallurgy, 2005 Step 2 Secondary steelmaking. In the case of both the basic oxygen process route and the electric arc furnace route, the molten steels, after being tapped (poured) from the furnace, undergo a further stage of processing before casting. This step is usually called secondary steelmaking. A number of routes are available.
Basic Process:In the basic electric arc steelmaking process a wide range of steel scrap is employed. The normal steel manufacturing procedure is to melt the scrap, which is recarburized with coke, anthracite, or broken electrodes, to give sufficient carbon at the melt out to assure a good carbon boil.

steel - Primary steelmaking Britannicasteel - steel - Primary steelmaking:In principle, steelmaking is a melting, purifying, and alloying process carried out at approximately 1,600° C (2,900° F) in molten conditions. Various chemical reactions are initiated, either in sequence or simultaneously, in order to arrive at specified chemical compositions and temperatures. Indeed, many of the reactions interfere with one another
Steel-making processes. Steel is made by the Bessemer, Siemens Open Hearth, basic oxygen furnace, electric arc, electric high-frequency and crucible processes. In both the Acid Bessemer and Basic Bessemer (or Thomas) processes molten pig iron is refined by blowing air through it in an egg-shaped vessel, known as a converter, of 15-25 tonnes Steelmaking Process - an overview ScienceDirect TopicsOxygen process. This is a modern steelmaking process by which a molten charge of pig-iron and steel scrap with alloying elements is contained in a basic lined converter. A jet of high-purity gaseous oxygen is then directed onto the surface of the liquid metal in order to refine it.
Aug 21, 2020 · Primary steelmaking has two methods:BOS (Basic Oxygen Furnace) and the more modern EAF (Electric Arc Furnace) methods. The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5%.
