Direct Reduced Iron Furnace Crusher

Direct reduced iron Wikipedia

Direct reduced iron, also called sponge iron, is produced from the direct reduction of iron ore to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes,

Direct Reduction Process an overview ScienceDirect Topics

The direct reduction processes in combination with the melting of directly reduced iron to produce steel in the EAF offer an alternative to the BF-BOF route. The basis of the direct reduction process is that solid sponge iron is produced by removing oxygen from the ore in a shaft furnace, rotary kiln furnace or fluidised bed. Sponge iron can be produced in the form of Direct Reduced Iron (DRI), Hot Briquetted

28 The direct reduction (DR) of iron ore, usually followed by electric arc steelmaking, is an 29 alternative route to the standard blast furnace-basic oxygen furnace route for making steel. The 30 annual DR iron production (86 Mt in 2017) remains small compared to the 1180 Mt of production of 31 blast furnace pig iron [1]. However, an attractive feature of DR compared to blast furnace reduction

of directly reduced iron per year. The module at the left is under con­ struction; its capacity will be 650,000 tons per year. The plant em­ ploys the Midrex direct-reduction process, in which a charge of lumps of iron ore and pellets of iron oxide is loaded into the shaft through the conveyor and then descends through a stream of hot reducing gas.

Iron Ore Reduction Gaylord Chemical

Coke formation is a persistent problem in direct iron ore reduction. Coke can decrease the gas flow as it accumulates in furnace tubes. It also acts as an insulator in the tube, requiring higher heat input to maintain furnace performance. DMS can be used as an additive in the gas feed to inhibit the formation of coke in the furnace tube and minimize these issues. Additionally, coke build-up

DRI production International Iron Metallics Association

Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form. The chemical reactions involved in the direct reduction of iron are the

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 low-residual 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 on

Direct Reduced Iron and its Production Processes

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 monoxide (CO) and hydrogen (H2
