Direct Reduction Of Iron Plant Schematics

Direct reduced iron - Wikipedia

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 direct reduction.

The Direct Reduction of Iron - ScienceDirect

In contrast to iron oxide reduction in a BF, direct reduction occurs in the solid state, and none of the components are melted. While this is good from an energy perspective, there is little or no way to remove impurities from the system, which are then carried with the direct reduced iron (DRI) product to the steelmaking furnace.
