Direct Reduced Iron and its Production Processes
16/03/2013 Direct 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. The reducing agents are carbon
Direct reduced iron
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 remove 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)). The direct reduction process is comparatively energy efficient. Steelmade using DRI requires sig

Process flow of the two versions of the top gas recycling BF (Zuo and Hirsch, 2009). The sponge iron formed in the direct reduction process is then melted in an electric arc furnace. In these processes, the iron oxides in the ore are reduced to metallic iron. In the next step, the raw iron is usually dropped into a torpedo ladle car where reagent is added to purify the iron from
Direct-Reduced Iron an overview ScienceDirect Topics
05/01/2012 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. Since much of the energy used is in the form of natural gas

Direct Reduced Iron (DRI) Cargo Handbook the world's
The direct reduction process uses pelletized iron ore or natural "lump" ore. One exception is the fluidized bed process which uses (requires) sized iron ore particles. Select few ores are suitable for direct reduction. The direct reduction process can use natural gas contaminated with inert gases, avoiding the need to remove these gases for other use. However, any inert

Midrex Process for Direct Reduction of Iron Ore IspatGuru
09/04/2017 Midrex Process for Direct Reduction of Iron Ore. Midrex is an ironmaking process, developed for the production of direct reduced iron (DRI). It is a gas-based shaft furnace process is a solid state reduction process which reduces iron ore pellets or lump ore into DRI without their melting using reducing gas generally formed from natural gas. The
Direct Reduced Iron (DRI) International Iron Metallics
Direct Reduced Iron (DRI) is the product of the direct reduction of iron ore in the solid state by carbon monoxide and hydrogen derived from natural gas or coal. 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
GREEN STEEL THROUGH HYDROGEN DIRECT REDUCTION
The direct reduced iron is discharged in either hot (HDRI) or cold (CDRI) condition or is hot briquetted into iron briquettes (HBI). Whilst natural gas is the most used feedstock for the direct reduction process, MIDREX® also offers its MXCOL™ technology which can use coal-based syngas as the reducing agent. This has potential in India, where natural gas supplies are
THE SMART CHOICE TENOVA
DRI Direct Reduced Iron DRI is reduced iron pellet and/or lump, which is cooled and discharged at low (ambient) temperatures. The process characteristics allow for independent control of the DRI metallization and carbon levels. Metallization can be adjusted at will, typically around 94% and higher. _ DRI carbon levels can be selected in
Direct Reduced Iron (DRI) Market Industry Analysis
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 production is set to drive the consumption of DRI; Increasing concerns regarding reduced
