converted into a gas containing hydrogen and carbon monoxide. As the iron ore moves down the furnace through gravity flow, the gas rises through the material column and removes oxygen from the iron carriers. This forms the direct reduced iron (DRI) which is typically composed of 90 to 94% iron. After the DRI exits
