Christian Rodrigues (Montanuniversitaet Leoben)12/05/2026, 11:00EEC 2.D Slag controlOral Presentation
The formation of freeze lining (FL) – a solidified slag layer that protects the furnace inner walls and refractory linings from chemical corrosion and physical degradation – is essential for the safe, energy-efficient, and long-term operation of high-temperature metallurgical reactors. Building upon a successful prior research program, a new consortium has been established, bringing together...

Sung Hwan Park (Hanyang University)12/05/2026, 11:20EEC 6.A Ongoing research in electric steelmakingOral Presentation
The hydrogen reduction iron- and steelmaking route is attracting global attention as an eco-friendly process for reducing carbon dioxide (CO2) emissions. It produces hot metal by melting hydrogen-based direct-reduced iron (H2-DRI) in an electric smelting furnace (ESF). In conventional blast furnace (BF) processes, the Si content of the hot metal is used as an indicator of hot metal quality and...

26. Mathematical Modelling of Slag Phase Composition during the EAF Process in Stainless SteelmakingProf. Ville-Valtteri Visuri (University of Oulu)12/05/2026, 11:40EEC 2.D Slag controlKeynote Presentation (paper for Ironmaking & Steelmaking special issue)
Contemporary stainless steelmaking is based predominantly on the duplex route, consisting of an electric arc furnace (EAF) followed by argon–oxygen decarburisation (AOD), or on the triplex route, in which EAF and AOD processing is followed by vacuum–oxygen decarburisation (VOD). Raw materials strongly influence slag chemistry in the EAF, and therefore understanding the properties and evolution...

Martin Sprunk (SECOPTA analytics GmbH)12/05/2026, 12:00EEC 2.D Slag controlOral Presentation
Currently, the European steel industry is undergoing a transformation, driven by two major forces. Firstly, to stay competitive in difficult market situations, new ways to improve processes, reduce losses and increase resource efficiency have to be developed. Secondly, economic and regulatory forces drive a transition of the steel industry towards production processes with lower carbon...

Mr Alexander Schlemminger (QuantoLux GmbH)12/05/2026, 12:40EEC 2.D Slag controlOral Presentation
Make the slag, and the steel makes itself. This expression underlines a central idea in electric arc furnace (EAF) steelmaking: slag is a key part of the process, even if it is not part of the product. “Good” slag influences energy consumption, refining quality, and overall process stability. However, recent findings strengthen the impression that today’s slag analysis methods often do not...
