| Abstract Scope |
Conventional steelmaking is highly energy-intensive, largely due to the melting steps in blast furnace–basic oxygen furnace (BF–BOF) and electric arc furnace (EAF) routes. To address this issue, a novel Hydrogen Reduction and Melt-less Steelmaking (HRMLES) process has been developed. This innovative approach utilizes direct hydrogen reduction of iron ore concentrate to produce iron powder, which is then consolidated into steel components via powder metallurgy without any melting step. In this research, the sintering behavior of hydrogen-reduced iron powders and the mechanical performance of the resulting steels were systematically investigated. Additionally, this research specifically explores alloy design tailored to the unique melt-less characteristics of the HRMLES process. Comparative analysis with conventionally produced steels demonstrates the potential of HRMLES as a low-carbon, energy-efficient alternative. |
