| Abstract Scope |
Direct reduced iron (DRI) and hot briquetted iron (HBI) are essential feed stocks for tramp element control in the electric arc furnace (EAF). Due to greenhouse gas (GHG) concerns related to CO2 emissions, the application of hydrogen as a substitute for natural gas as a reductant in DRI production is being widely considered as a solution to reduce GHG emissions in ironmaking. This study focuses on the melting behavior of carbon free hydrogen reduced DRI (HDRI) pellets in the EAF to determine the impact of carbon free DRI use on heating and melting times. A computational simulation has been developed to predict the melting behavior of hydrogen DRI and carbon containing DRI and corroborated with experimental results. |
