Smelting sponge iron in electric arc furnace. The HYBRIT process involves removing the oxygen from the iron ore using hydrogen. The reduction occurs at a lower temperature and the result is so-called sponge iron (direct reduced iron). The sponge iron is smelted in a furnace, powered by electricity. The furnace is called an Electric Arc Furnace ...

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.
