Direct reduced iron, Direct reduced iron (DRI), , (HDRI) is iron not cooled before discharge from the reduction furnace, that is immediately transported to a waiting electric arc furnace and charged, thereby saving energy , DRI contains some siliceous gangue, which needs to be removed in the steel-making process HistoryElectric Arc Furnace for Clean Steel & Environment, Utilization of EAF for melting this DRI results in production of steel quite economically Advantages of EAF are many It is the equipment which can be tailor designed, specifically suiting the requirement of the processProjects Area, Process Integration (PI) The pathway PI covers the existing steelmaking routes (BF / BOF and DRI / EAF) using fossil fuels (coal, natural gas, etc) and how these processes must be ,Direct Reduced Iron (DRI) | International Iron Metallics ,, See more information about the production of DRI Most gas-based direct reduction plants are part of integrated steel mini-mills, located adjacent to the electric arc furnace (EAF) steel plant DRI can be either hot or cold charged to the EAFsteel cost electric arc furnace 2018 steelmaking economics, The steel product for which the cost is shown above is a metric tonne of EAF liquid steel The cost is for a notional producer - a typical size plant of about 1m t/year capacity, based in Japan, using a scrap charge to EAF [no DRI or irons], and producing commodity grade carbon steel for long products with average labour productivity.
Cost Effectiveness Analysis of HYL and Midrex DRI ,, Cost Effectiveness Analysis of HYL and Midrex DRI Technologies for the Iron and Steel-Making Industry By , (EAF) The BF-BOF is a two-step process First, in the blast furnace, mined iron ore is combined , In 2014, 739% of crude steel production was through the BF-BOF method (World Steel in Figures, 2015) The secondary way steel is made .Resources Trend and Use of Direct Reduced Iron in ,, arc-furnace (EAF) process This rapid increase in crude steel production has also resulted in significant increases, as shown in Fig 3, in the prices of iron ore and coking coal, the principal raw materials of iron and steel3) There are some background factors: eg, i) the current BF process relies heavily on high-grade ore mined inFACT SHEET Steel industry co, Steel industry co-products 1 Figure 1: Main solid co-products by steelmaking routes2 An average value is shown for the EAF route (see Figure 1), as EAF plants often use a mix of DRI and recycled steel feeds On average the production of one tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of co-products These include slags.Introduction to direct reduction technology and outlook ,, material for the EAF The Direct Reduced Iron (DRI) is a valuable alternative to the high , Fig 2 - Main process routes for world steel production in 2012  , compared to the alternative route BF-BOF The steel making industry is characterized by an intensive use of fossil fuels, whichPROCESSI The EAF technology evolution and the Consteel® ,, The EAF technology evolution and the Consteel® system P Argenta, M Bianchi Ferri During the past 11 years, steel production by the electric arc furnace route (EAF) has grown on a worldwide basis by 41%/year, while the total steel production has grown by 27% , of mixed BF-EAF installations In fact, several integrated.
