Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes, one example bein Direct Reduced Iron (DRI) Market Outlook & Key Findings. As direct reduced iron significantly lowers the need for batch charges that eventually raises the overall cost-efficiency and productivity of the process, DRI remains among the favored feed for electric arc furnaces (EAF) DRI market is set for 7% growth in 2021, as rise in EAF steel 2021. 3. 30. Regardless of the steelmaking route, there is a form of direct reduced iron (DRI) for every application. DRI is a premium ore-based metallic (OBM) raw material made by removing chemically-bound oxygen from iron oxide pellets and lump ores without melting. DRI is high in iron content and low in copper and other undesirable metals, tramp elements, During the last four decades, a new route of ironmaking has rapidly developed for direct reduction (DR) of iron ore to metallic iron by using noncoking coal/natural gas. This product is known as... Published date: 18 October 2018. Share: US steelmaker Nucor will take its Louisiana direct-reduced iron (DRI) plant offline for 60 days in 2019 as part of a $200mn investment designed to boost reliability following multiple unplanned outages in recent years. 2012. 1. 5. 4.4 Direct Reduction. Direct reduced iron is iron ore in the form of lumps, fines or pellets that have had the oxygen removed by using hydrogen and carbon monoxide. Typical sources of carbon monoxide are natural gas, coal gas, and coal. Other energy inputs into the production process often include oil and electricity. 2013. 12. 9. MIDREX ® Direct Reduced Iron Cooling Gas Scrubber Cooling Gas Compressor Iron Oxide Natural Gas is used as a reductant. Coke is not required. (Pellets/Lump Ore are reduced to produce DRI without being melt in the shaft furnace.) DRI is fed to EAF to produce steel. As the iron oxide descends through the furnace, the iron oxide is heated and reduced 2021. 3. 18. First Vice President, Es’haq Jahangiri inaugurated a direct-reduced iron (DRI) production plant with annual production capacity of 1 million metric tons in Bardsir in the southeastern province Dri Direct Reduced Iron Hbi Turnkey Project picture from Suzhou CMT Engineering Company Limited view photo of Hot Briquetted Iron, Hbi, Cbi.Contact China Suppliers for More Products and Price.
