Direct Reduced Iron (DRI) Cargo Handbook the world's

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 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 calledWhat is directreduced iron (DRI)? Most of the iron used by humanity goes through the process of direct reduction The main and most economical method of recovering iron from its ore known is the carbothermal method of direct reduction from the ore by means of carbonbearing materials: FeХOY+C=Fe+CO2 The oldest and most common method is to smelt iron (pig iron) in hearths where ironDirectreduced iron URMCompanyDirect 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 gasbased direct reduction plants are part of integrated steel minimills, located adjacent to the electric arc furnace (EAF) steel plant DRI can be either hot or cold charged toDirect Reduced Iron (DRI) | International Iron Metallics

Direct Reduced Iron and its Production Processes – IspatGuru

16/03/2013· In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion Direct reduction can be defined as reduction in the solid state at O2 potentials which allow reduction of iron oxides, but not of other oxides (MnO, and SiO2 etc), to the corresponding elements Since reduction is in the solid state, thereDuring the reduction process in the production of direct reduced iron, either coal or a special gas — commonly containing a combination of carbon monoxide and hydrogen — is used This mixture functions as a reducing agent and facilitates the decrease in the iron's oxygen and carbon content The result is a type of iron that is 9097% pure, containing only minuscule amounts of carbon andWhat is Direct Reduced Iron?

The increasing role of direct reduced iron in global

Direct reduced iron (DRI), produced by the reaction between iron ore and reducing gasses, is used as a source of lowresidual iron, in addition to ferrous scrap and pig iron, in the production of steel mainly through the electric arc furnace (EAF) route of steelmaking The main DRI technologies in use are those of Midrex and Hyl, but in recent years a myriad of newer processes emerged based onThe Direct Reduction of Iron Ore Methods of making steel without smelting ore in a blast furnace are becoming increasingly economic where steelmaking facilities of modest scale are needed, notably in the developing countries The iron ore from which iron and steel are made is an oxide, that is, a chemi­ cal compound of iron (Fe) and oxy­ gen (0) Common forms of ore are hematite (Fe20a) andThe Direct Reduction of Iron Ore JSTORspecial grades of steel in the same steelmaking or refining process [1] Direct reduced iron (DRI) is a highquality metal product obtained from iron ore and it is used as raw material in electric arc furnaces, blast furnaces, and in other more recent steelmaking processes [2] 2 Total DRI Output in the World With the output of approx 432 mil tones in 2000 DRI accounts for 3 – 4 % of theSTATE OF THE DIRECT REDUCTION AND REDUCTION SMELTING
