K1-MET at the “60th Metallographie-Tagung” in Leoben, Austria, from 23–25 September 2026 For six decades, the “60th Metallographie-Tagung” has been a key gathering place for academia and industry in the German-speaking world. Zeljka Simicevic (K1-MET) attended the 60th anniversary conference at the Technical University of Leoben and gave a presentation titled “Mineralogy, Petrography, Low-Temperature Decomposition Resistance, and Reducibility of Synthetic Sinter Samples with and without Carbonate Iron Ore”. The aim of the study was to compare two iron ore sintered bodies with different feed mixtures. The sintered bodies were examined mineralogically and petrographically. The analysis revealed differences in hematite and magnetite content. Carbonate ore and higher coke fines content improved low-temperature disintegration resistance. A lower coke fines content, on the other hand, led to better reducibility. photo right: Zeljka Simicevic, K1-MET GmbH #K1MET #forschung #research #metallography #mineralogy #petrography #sinter #decarbonisation

K1-MET at the 4th Green Steel World Conference Mohammad Jafarzadeh presented his work at the 4th Green Steel World Conference in Duesseldorf, Germany, from 23 to 24 September 2026. The research is conducted within the HELIOS - MSCA DN , which focuses on innovative hydrogen-based technologies for green steel production. His oral presentation, entitled “The Impact of Hydrogen Flow Rate on the Reduction Efficiency of Cr2O3 During Hydrogen Plasma Smelting Reduction (HPSR) Process”, examined the influence of hydrogen flow rates on the reduction efficiency of chromium oxide. The study investigated the thermodynamic and operational aspects of hydrogen plasma reduction, evaluating reactor performance under different hydrogen flow rates. Key parameters included the reduction degree, hydrogen utilisation, metallisation degree, power input and arc stability. Experimental results were supported by metallographic observations and process characterisation. The findings provide insights into the potential of hydrogen plasma-based chromium production and its contribution to the decarbonisation of the ferrochrome and stainless steel industries. photo: Presentation by Mohammad Jafarzadeh, K1-MET GmbH #K1MET #forschung #research #hydrogen #HPSR #decarbonisation #steelindustry

K1-MET at the International Colloquium on Refractories (ICR) 2026 in Aachen, Germany, from 16–17 September 2026 Jeronimo Guarco (K1-MET GmbH) gave a presentation on “Experimental and Numerical Investigation of Shear-Induced Erosion of Alumina Refractories in Alumina-Saturated Slag”. Using a novel finger-test apparatus and CFD simulations, the study investigated high-temperature erosion profiles and the evolution of erosion parameters over time. The results show that the critical shear stress decreases as the interaction between refractory and slag develops, providing new insights into the combined effects of precorrosion and shear-driven erosion under real operating conditions. The findings contribute to a better understanding of refractory wear and could support efforts to extend refractory service life in metallurgical vessels. Zeinab Naji gave a talk on “Thermomechanical Response Analysis of Refractories in a Ruhrstal-Heraeus Degasser Vessel”. The study uses von Mises creep model, the Drucker–Prager model, and the concrete damage plasticity model to evaluate inelastic response of the refractory lining in direct contact with molten steel. The results demonstrate that only creep and shear mechanisms are activated during the initial preheating phase and govern inelastic deformation near the hot face, while tensile failure contributes only negligibly. Furthermore, creep leads to a larger joint opening at the hot face and results in a reduced radial displacement of the steel shell. photo: Jeronimo Guarco and Zeinab Naji, K1-MET GmbH #K1MET #research #forschung #refractories #erosion #metallurgy #CFD #slag #wearmechanisms #refractorymaterials #steelmaking

K1-MET at the 11th IUPAC International Conference on Green Chemistry (ICGC) Nina Plankensteiner from K1-MET presented her research at the 11th IUPAC in Lisbon, Portugal, on 8–12 September 2026. Her presentation focused on CO2 electrolysis using real industrial CO2 captured from an integrated steel mill. The study demonstrates, for the first time, the integration of amine-based CO2 capture with a TRL 6 pilot-scale electrolysis unit to produce CO for reuse in the steel industry. The results highlight the potential of this technology for industrial CCU value chains, achieving up to 1 t CO2/day conversion with 80–90% selectivity to CO. A further step towards closing carbon cycles in the steel industry. photo: Nina Plankensteiner, K1-MET GmbH #K1MET #forschung #research #CO2electrolysis #CO2capture #decarbonisation

We are proud to share that an article with K1-MET as a co-author ( Michael Andreas Zarl ) is ranked among the Top 10% most-viewed papers of 2024 in the journal! The paper was authored by Henri Pauna together with Daniel Ernst, Isnaldi Rodrigues de Souza Filho, Michael Kulse, Ömer Büyükuslu, Matic Jovičević-Klug, Hauke Springer, Marko Huttula, Johannes Schenk, Timo Fabritius and Dierk Raabe as further co-authors. The article describes how OES and plasma color analysis can provide real-time insights into the HPSR process — from plasma composition and temperature to slag formation and reduction dynamics. Key takeaway: simple optical diagnostics can become powerful tools for monitoring and optimizing hydrogen-based ironmaking. We are excited to build on this towards data-driven, low-carbon steel production! #K1MET #research #forschung #hydrogen #steelmaking #OES #decarbonization

K1-MET hosted the Kick-off meeting of the Interreg ATCZ project CARMA. The project will be coordinated by K1-MET, and the scientific partners are Mendel University in Brno, Johannes Kepler University Linz and University of South Bohemia in České Budějovice. CARMA converts CO2 emissions into methane through electrolysis and uses microorganisms to produce high-quality biomass from it. The nutritional composition of this alternative protein source is then evaluated, and its suitability as fish feed is tested. CARMA combines modern technology with ecological considerations and contributes to a circular economy. The project is funded by the European Regional Development Fund (programme Interreg Austria—Czechia 2021–2027), project ATCZ00278. photo from left to right: Nina Plankensteiner (K1-MET), Mark Hlawitschka (JKU), Sabine Spiess (K1-MET), Laura Androsch (K1-MET), Martin Pumera (Mendel University), online participants: Koushik Roy and Lucie Rybová (University of South Bohemia), Anna Jánová and Lenka Hynková (Mendel University). #K1MET #research #CO2electrolysis #3Delectrodes #microbes #bioreactor #protein #fishfeed

K1-MET at the EEC 2026 K1-MET participated in the 4th European Electric Steelmaking Conference (EEC 2026), held in Milan, Italy, from 11 to 13 May 2026. Erwin K. Reichel (K1-MET) gave a presentation on “Stability Enhancement of DC Arcs in Reducing Argon-Hydrogen Atmospheres via Current Regulation”. Co-authors are Cameron Quick (K1-MET), Michael Andreas Zarl (K1-MET), Thomas Voglhuber-Brunnmaier (JKU Linz), Lukas Ecker (JKU Linz) and Simon Schneiderbauer (JKU Linz). Erwin presented progress made in the projects Lightbow, PlasmArc4Green, and SuSteel (follow-up) on the modeling of the Hydrogen Plasma Smelting Reduction (HPSR) process. HPSR is a potentially zero-emission route to liquid iron to be used in sustainable steelmaking. Hydrogen is ionised in an electric arc to reduce iron ore in the melted stage. Detailed understanding and control of the arc dynamics is crucial to increase hydrogen utilisation and energy efficiency – key parameters to enable the next up-scaling steps. In addition, Daniel Kavić (K1-MET) contributed as co-author to the presentation “Mathematical Modelling of Slag Phase Composition during the EAF Process in Stainless Steelmaking” by Ville-Valtteri Visuri (University of Oulu). Further co-authors are Ilpo Maekelae (University of Oulu) and Matti Aula (Outokumpu Stainless Oy). photo: Presentation by Erwin Reichel, K1-MET GmbH #K1MET #forschung #research #steelmaking #HPSR #hydrogen #hydrogenplasmasmeltingreduction #EEC2026
