In the direct-reduced iron (DRI) process, the iron ores are reduced directly to sponge iron by gaseous reducing agents! In the electric steel process, the sponge iron obtained from the direct reduced iron process is used for crude steel making. In general, scrap is also added to this process as well as pig iron from the blast furnace process.
