| Abstract Scope |
Electric Arc Furnace (EAF) processes recycle high levels of scrap steel. Inevitably, the melted scrap contains residual tramp elements which must be diluted to an acceptable level. Clean or “Virgin” iron units must be utilized to dilute the scrap mix. DRI, hot briquetted iron (HBI), sponge iron, and pig iron are all forms of virgin iron units. Conventional virgin iron sources utilize some form of carbon base reductant to reduce iron oxide, typically hematite or magnetite, into iron. The use of hydrogen as a reductant instead of carbon or carbonaceous gas has been viewed as a promising alternative.
This research includes the construction, commissioning, and production of an H-DRI pilot plant, as well as the melting performance of H-DRI in comparison to C-DRI. Melting performance is analyzed at both the laboratory and commercial level. Additionally, the potential benefit of using ionized hydrogen (hydrogen plasma) as a reductant is also investigated. |
