Special Issue Information

Dear Colleagues,

Electric arc furnace steelmaking is one of the most important steelmaking routes and currently accounts for almost 30% of worldwide crude steel production. In certain regions and countries, the share is significantly higher, like e.g. North America with a share of electric arc furnace steelmaking of 65–70%. Considering the transformation concepts of the integrated steel mills to decarbonize their steel production and the increasing scrap availability in Asia, it can be expected that the share of scrap-based EAF steelmaking will continue to increase in the coming decades. Furthermore, the EAF serves as the basis for plans to melt DRI produced using hydrogen reduction to produce carbon-free steel.

In this Special Issue of Metals, we welcome contributions on recent advances in all aspects of electric arc furnace steelmaking including but not limited to EAF process optimization and efficiency, the application of new sensors and equipment, reduction of CO2 emissions and environmental impact, process modeling and simulation, scrap handling and alternative/new charge materials as well as slag properties and valorization. We also encourage the submission of reviews on EAF steelmaking technologies.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs).

Hydrogen-based direct reduction is a promising technology for CO2 lean steelmaking. The electric arc furnace is the most relevant aggregate for processing direct reduced iron (DRI). As DRI is usually added into the arc, the behavior in this area is of great interest. A laboratory-scale hydrogen plasma smelting reduction (HPSR) reactor was used to analyze that under inert conditions. Four cases were compared: carbon-free and carbon-containing DRI from DR-grade pellets as well as fines from a fluidized bed reactor were melted batch-wise. A slag layer’s influence was investigated using DRI from the BF-grade pellets and the continuous addition of slag-forming oxides. While carbon-free materials show a porous structure with gangue entrapments, the carburized DRI forms a dense regulus with the oxides collected on top. The test with slag-forming oxides demonstrates the mixing effect of the arc’s electromagnetic forces. The cross-section shows a steel melt framed by a slag layer. These experiments match the past work in that carburized DRI is preferable, and material feed to the hotspot is critical for the EAF operation. Full article
