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 exitsEffect of Direct Reduced Iron Proportion in Metallic,,rolled bars of low carbon steel slightly decrease whereas elongation increases.
