  • Direct reduced iron Wikipedia

    Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).iron ore pellets production flow chart ppt,OVERVIEW OF THE STEELMAKING PROCESS. 2019-1-22 · Direct reduction Scrap Ladle (Refining) Electric arc furnace (Steelmaking) Iron Ore Pellets Electric Arc Furnace Steelmaking Continuous casting Design by Blisscommunication Cover photo: ThyssenKrupp Steel Tubes photo: Salzgitter The process shown above is illustrative only and is not designed to show the steelmaking process in detail.
