Direct Reduction Iron Making

Direct reduced iron - Wikipedia

Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)). The direct reduction process is comparatively energy efficient. Steelmade using DRI requires significant

DRI production International Iron Metallics Association

DRI 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 monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

GASIFICATION AND THE MIDREX? DIRECT REDUCTION PROCESS

The production of direct reduced iron (DRI), a basic raw material for making steel, is concentrated in a few countries in the Middle East and Latin America. One primary reason is that natural gas, the main fuel source for most DRI processes, is too costly in many of the steel making regions of the world.

27/04/2016  Another alternative to hot molten iron making is the direct reduction method. In this method, iron is reduced in its solid state using either coal or natural gas as a fuel. One advantage of this method is that iron can be added as lumps, pellets, or fines, and if coal is used, it does not need to be coked. Therefore, a sinter/pellet and a coke plant is not needed for this operation. The end ...
