Directreduced Iron An Overview Sciencedirect Topics

Jan 05, 2012 In direct reduction the ore is heated to temperatures below its melting point. Direct energy requirements per net ton of direct reduced iron are in the order of 10,000 MJ. The product is 90 to 95 metallized and hence is suitable as a charge in blast, basic oxygen, and electric arc furnaces.

Direct Reduced Iron Dri Cargo Handbook The Worlds

Direct-reduced iron DRI, also called sponge iron, is produced from direct reduction of iron ore in the form of lumps, pellets or fines by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen H2 and carbon monoxide CO which acts as reducing agent. This process of directly reducing the iron ore in solid form by reducing gases is called direct reduction.

Direct Reduced Iron Process Tecscience

Jun 21, 2018 In the direct-reduced iron DRI process, the iron ores are reduced directly to sponge iron by gaseous reducing agents Electro-steel process. In the electric steel process, the sponge iron obtained from the direct reduced iron process is used for crude steel making. In general, scrap is also added to this process as well as pig iron from the blast furnace process.

NIPPON STEEL ENGINEERING CO., LTD. provides new iron source technology that enables the achievement of productivity improvements, operational cost reductions, CO 2 emissions reductions, and capital investment reductions through the optimal combination of Tenova HYL and Danielis natural gas-based direct-reduced iron technology ENERGIRON

The Increasing Role Of Direct Reduced Iron In Global

newer processes, called direct smelting processes, reduce iron oxide to metallic iron in a molten state directly from iron oxide to give a similar product to that of the blast furnace.

Direct Reduced Iron Midrex Technologies Inc

Feb 28, 2021 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.

Direct Reduced Iron Aist

Direct Reduced Iron Technology Committee MISSION To focus on the emerging market and technological trends for the production, handling, and use of direct reduced iron DRI and hot briquetted iron HBI products as well as present and future alternative iron production technology.

State Of The Direct Reduction And Reduction

Direct reduction is defined as a process of producing solid iron product out of small-grain ore, lump ore or pallets, applying natural gas or coal-based reducing agents at relatively low temperatures i.e. at around 1000 O C.

White Paper Influence Of Directreduced Iron Percentage

substitute materials such as direct reduced iron DRI pellets, hot briquetted iron HBI, iron carbide, etc. are used when producing steels with low residual elements via EAF steel making. At the present time, the most common forms of direct reduced scrap substitute materials are DRI and HBI. DRI is produced from a combination of pelletized and lump
