Description Application Shipment - Storage Risk factors. 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.
Jan 25, 2020 Based on the analysis of treated syngas typically from a Lurgi gasifier, expected DRI characteristics for syngas based direct reduction DR plant are 93 or more of metallization and upto 2 C. The typical syngas analysis from the coal gasification plant consists of CO 26 , H2 55 , CH4 16 , CO2 2 , and N2 1 .
Mar 16, 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.
Jan 05, 2012 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.

4 weeks Salzgitter Gets Funding Approval For Construction Of Direct Reduced Iron Plant Business Insider RTTNews Salzgitter AG SZGPF.PK, SZGPY.PK said Federal Environment Minister Svenja Schulze handed over the funding approval for the construction of the first direct reduced iron plant to be operated flexibly by hydrogen and natural gas
The direct reduced iron DRI it produced was supplied to Oregon Steel Mills OSM in Portland, Oregon, which operated an electric arc furnace EAF. To the delight of everyone involved, OSM established a new production record using DRI. As a result, OSM contracted Midland-Ross to build a full-scale commercial protype plant in Portland.
All effective methods of direct reduction actually use the same process rich iron ore fine concentrate or pellets is reduced by a special gas mixture up to the iron content of 85-90. This explains why the production of direct-reduced iron is mainly concentrated in countries with large reserves of oil oilwell gas, natural gas and iron ore ...
Direct Reduced Iron DRI, also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI, iron ore is reduced in its solid state unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and Mexico.
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 ...

Overview. Hot Briquetted Iron HBI is a premium form of DRI that has been compacted at a temperature greater than 650 C at time of compaction and has a density greater than 5,000 kilograms per cubic metre 5,000 kgm 3.. HBI was developed as a product in order to overcome the problems associated with shipping and handling of DRI - due to the process of compaction it is very much less ...
Direct Reduced Iron is discharged hot from the reduction furnace and screw-fed into the nip between two counter rotating rollers. Pockets in the synchronously rotating rollers form the briquettes. This process occurs at high temperatures typically approx. 700 C and high pressing forces.
