Mar 11, 2016· The presentation describes different processes for the production of direct reduced iron.
DRI Products Versatile Orebased Metallics . 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/cc
Web alert: Considerations for the carriage of 'Direct Reduced Iron' cargoes 02 April 2014. Direct Reduced Iron's (B) propensity to selfheat (and associated hazards) requires ships fixed to carry this cargo to ensure that their cargo holds are properly inerted for the duration of its voyage.
Direct Reduced Iron offered by Prem Enterprises, a leading supplier of Sponge Iron in Nehru Nagar, Durg, Chhattisgarh. The Company was incorporated in 1994 and is registered with IndiaMART. | .
Aug 06, 2016· Directreduced iron (DRI), also called S ponge iron, is produced from direct reduction Iron (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. 'Reduced iron' derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at high temperatures in the presence of hydrocarbonrich gasses.
Pig iron, principally nodular pig iron, is also produced through the smelting of ilmenite in electric furnaces, as a byproduct of titanium dioxide slag production. With its defined and closely controlled specification and the absence of metallic impurities, pig iron is a reliable and consistent charge material for both electric steelmaking and ...
Direct reduction is the process of converting iron ore into metallic iron without melting. Direct reduced iron (DRI) is used as a high quality feed material in electric arc furnace steelmaking, oxygen steelmaking, ladle metallurgy, blast furnace ironmaking, and foundries. Normally 90 to 95% of the iron in DRI .

Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BFBOF and ScrapEAF 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.
Iron ores and direct reduced iron Determination of size distribution by sieving This document specifies the methods to be employed for determination of size distributions by sieving of iron ore and direct reduced iron (excluding briquetted iron), utilizing sieves having aperture sizes of 36 µm or larger.
'Direct reduction' refers to processes which reduce iron oxides to metallic iron below the melting point of iron. The product of such solid state processes are called direct reduced iron (DRI), whereas the product of the blast furnace is referred to as hot metal in the molten state, or pig iron in the solidified form.
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
Dec 20, 2014· Direct reduced iron . DRI is basically technically expressed as iron ore and these ore of iron which has been reduced to metal without melting it. Hot briquetted iron (HBI) is a densified form of DRI to facilitate its handling and transport.
Directreduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in solid form of lumps, pellets or fines) by a reducing gas derived from natural gas or coal. It is a manufactured metallic material produced by removal of iron oxide at °C without reaching the melting point of iron by interaction with reductants (H2+CO).
Directreduced iron (DRI), also called sponge iron [1], 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.
Reduced demand and high stock will lead the Iron ore price fall down Mon, 10 Feb 2014 03:43:00 GMT Influenced by the low price of steel, falling volume of steel and iron, the demand for raw material iron ore is hard to change, and the iron ore price still kept a downtrend. ...
direct reduced iron ore plant Mine EPC. Direct reduced ironWikipedia. Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elementary carbon produced from natural gas or coal.
Directreduced 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 . » More detailed Cardero Produces Premium Direct Reduced Iron Grade Pellets .

CARRIAGE OF DIRECT REDUCED IRON (DRI) BY SEA – CHAN GES TO THE IMO CODE OF SAFE PRACTICE FOR SOLID BULK CARGO Members will be aware of the general concerns that exist with regard to the carriage of Direct Reduced Iron (DRI) by sea. These concerns have increased significantly since the loss of life ... Carriage of Direct Reduced Iron, March 10 ...
direct reduced iron produced with the various processes of direct reduction. Because, during hot briquetting, the large specific surface area of direct reduced iron is drastically reduced, the well known problems caused by reoxidation, overheating are avoided.
