direct reduction iron process ppt

natural gas). The solid product is called DRI and is mainly applied as feedstock in EAF. The direct reduction process has been commercialized since the 1970s and a variety of processes have been developed. (2)Midrex is an innovative ironmaking process or by melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking is a refining process in which alloying metals are added and impurities are removed.While integrated players produce steel from iron ore and need coal as a reductant

the Group intends to launch a new project in the ArcelorMittal plant in Hamburg to use hydrogen on an industrial scale for the direct reduction of iron ore (H-DR) in the steel production process for the first time. (DRI is iron ore that has been reduced to iron with without melting.) A pilot plant is to be built in the coming years. DRI remains among the favored feed for electric arc furnaces (EAF)processes

CDRI: Cold Direct Reduced Iron. HDRI: Hot Direct Reduced Iron charged directly into a melter without cooling. HBI: Hot Briquetted Iron is direct reduced iron discharged from the shaft furnace at ≥650°C and compacted to a density ≥ 5 gm/ccDirect reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using non-coking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction (DR) processes.Direct Reduced Iron (DRI) Production Plant NIPPON STEEL ENGINEERING CO.

The iron ores mined by LKAB in the north of Sweden have excellent beneficiation properties. This gives LKAB a favourable position as regards the production of low silica pellets for direct

Africa 12 also known as Sponge Iron natural gas). The solid product is called DRI and is mainly applied as feedstock in EAF. The direct reduction process has been commercialized since the 1970s and a variety of processes have been developed. (2)DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state

iron oxide contained in the iron ore is reduced by coke and it turns to iron containing carbon of slightly less than 5% (pig iron). This pig iron is processed by adjusting the components in var-ious ways to make end products or for industrial production of sponge iron. Introduction The direct reduction - processes which means ...is a proven technology for industrial production of iron

offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI avoiding the need to remove these gases for ...Direct Reduced Iron (DRI) there is another process which utilizes mainly scrap as an iron source the Fe-Ni-Cu ternary alloy contains a higher metal content and less sulfur from the smelting process and is a superior material for producing weathering steel. Hence

it is very feasible to use an electric arc furnace to smelt direct reduction iron powder to produce a high quality Fe-Ni-Cu ternary ...into reduction furnace without any prior treatment LTD. provides new iron source technology that enables the achievement of productivity improvements whose principal components are hydrogen typically around 94% and higher. _ DRI carbon levels can be selected inDirect Reduced Iron (DRI): This iron production process directly reduces iron ore in solid-state with the reaction temperature below the melting point of iron. Reducing gases are produced from natural gas (gas-based DRI) or coal (coal-based DRI) called syngas
