The melting behavior of conventional carbon-bearing direct reduced iron (DRI), hot briquetted iron (HBI), and carbon-free DRI produced by hydrogen reduction has been investigated in a simulated electric arc furnace (EAF) melting environment. A testing apparatus was created to document the melting rates under various bath conditions in slag and steel. The data acquired is compared to established melting mechanisms and models. The results of this investigation sheds light on the potential process effects of melting hydrogen-produced DRI in the EAF.
