Smelting sponge iron in electric arc furnace Hybrit

Smelting sponge iron in electric arc furnace Hybrit

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 (EAF). This opens in a new window.
