Description of Direct Reduced Iron (DRI Steel) 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 elemental carbon produced from natural gas or coal. Many ores are suitable for making direct reduction iron.

Conditions for Minimizing Direct Reduction in Smelting Reduction Iron Making

In a 2 stage-smelting reduction process, it is favorable to lower the reduction degree of iron ore in a pre-reducing unit by lowering its temperature to avoid any troubles due to stickiness of high reduced iron ore. However, less pre-reduced iron ore can induce direct

Direct Reduction Process Description | …

Process Description. R&D Trends. In a direct reduction process, lump iron oxide pellets and/or lump iron ore, are reduced (oxygen removed) by a reducing gas, producing direct reduced iron (DRI). If the cooling stage is omitted, the DRI can be immediately briquetted into hot briquetted iron (HBI). The reducing gas can be generated externally to

North Africa: Focus on Direct Reduction Ironmaking - …

Direct reduction of iron – extracting metallic iron from iron ores without melting the material – is one of the first industrial processes developed by humans. Early ironmakers were unable to achieve the high temperatures required to melt iron ores, so they heated them together with charcoal to produce a pasty, metallic substance which they could hammer into tools and other implements.
