• Why is scrap used in a blast furnace Quora

    Oct 04, 2018· The Old Metallurgical Engineer and Steelmaker says: Ferrous scrap (steel or iron scrap) is NOT used in a blast furnace. It has been tried: shredded scrap has been added to the iron ore burden of a blast furnace, but no improvement in “hot metal” (

  • Why Chinese steelmakers are using less scrap in their

    Jul 10, 2019· The usage of scrap in integrated carbon steelmaking has traditionally been limited to that charged into the basic oxygen furnace (BOF) before the hot metal is added. Other than serving as a necessary coolant during steelmaking, the respective ps of hot metal and scrap, the latter related to avaiility, largely determined how much scrap

    Further, solid pig iron is used as “pure” raw material and carbon source in EAFs. The blast furnace–BOF route produces almost 66% total crude steel, and EAF route accounts for about 31%, while the blast furnace–open hearth process, which dominated steelmaking in the first half of the 1900s, had only a share of about 3% left [7].

  • Steel Basic oxygen steelmaking Britannica

    Steel Steel 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

  • Steelmaking Wikipedia

    Primary steelmaking involves converting liquid iron from a blast furnace and steel scrap into steel via basic oxygen steelmaking, or melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking involves refining of the crude steel before casting and the various operations are normally carried out in ladles.
