  • Steelmaking and Refining | Introduction to Chemistry

    Secondary steelmaking uses scrap steel as the primary raw material. Gases created during the production of steel can be used as a power source. Primary Steelmaking. Basic oxygen steelmaking is a method of primary steelmaking in which carbon-rich molten pig iron (the iron created in the blast furnace) is made into steel.

  • Dynamic Modeling of the Main Blow in Basic

    T o improve control of basic oxygen steelmaking and to enable dynamic optimization, the process should be modeled dynamically. To develop a dynamic model, the influence of changes in control variables, such as the lance height, the oxygen blowing rate, and the addition rates, on the process should be known.

  • Steel - Basic oxygen steelmaking | Britannica

    18/8/2020· Basic oxygen steelmaking. More than half the world's steel is produced in the basic oxygen process (BOP), which uses pure oxygen to convert a charge of liquid blast-furnace iron and scrap into steel. The basic oxygen furnace (BOF) is a refractory-lined, tiltable converter into which a vertically movable, water-cooled lance is inserted to blow oxygen through nozzles at supersonic

  • WHAT IS STEEL MAKING PROCESS: BRIEFLY

    As oxygen is passed through the molten pig iron to lower the carbon content of the alloy, the process is also called basic oxygen steelmaking. The word basic is added with it for the chemical nature of the refractories- magnesium oxide and calcium oxide. The basic principal of it is to lower carbon content in pig iron in order to make pure

  • Chemistry of Steelmaking by Basic Oxygen

    Chemistry of Steelmaking by Basic Oxygen Furnace. During the steelmaking process by basic oxygen furnace (BOF), impurities in hot metal such as carbon (C), Silicon (Si), manganese (Mn), phosphorus (P) etc. are removed by oxidation for the production of liquid steel. Oxidation is carried out with high purity oxygen gas which is blown in the BOF.
