2019.1.1 Overview of DR processes Direct reduction processes reduce iron ore (in the form of lumps, pellets or fines) to the solid state using a reducing gas to produce
Read More2016.3.30 During the last four decades, a new route of ironmaking has rapidly developed for direct reduction (DR) of iron ore to metallic
Read More2018.6.21 In the direct-reduced iron (DRI) process, the iron ores are reduced directly to sponge iron by gaseous reducing agents! Electro
Read MoreDRI production. 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
Read More2012.1.5 DRI can be produced in powder, pellet, lump, or briquette form. The powder, pellets, and lumps retain the shape of the iron oxide material fed into the DR
Read More2017.10.17 Direct iron reduction processes produce a form of sponge iron called direct reduced iron (DRI). Smelting reduction and direct iron reduction can reduce energy input, lower greenhouse gas
Read MoreThe primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods
Read More2021.2.23 Steelmaking based on direct reduced iron (DRI, and its compacted derivative hot briquetted iron, HBI) is an anticipated important global alternative to current steel production based on FeOx reduction in
