15 Okt - Identifying industrial symbiosis opportunities using metallurgical process modelling

📅 15 oktober 2025 kl. 10:15–11:00 på Teams
🎤 Joakim Lundgren & Erland Nylund
💡 Transitioning from blast furnace to EAF steelmaking alters by-product and energy flows. This study models new symbiosis opportunities for waste and energy recovery in a fossil-free steelmaking ecosystem.

22 Okt - Optimization of Biocarbon Production for Steelmaking

📅 22 oktober 2025 kl. 10:15–11:00 på Teams
🎤 Kentaro Umeki & Yusuf Tolunay Kilic
💡 Future fossil-free steelmaking processes will rely heavily on hydrogen as a reducing agent, significantly reducing the need for carbon. However, carbon-containing solids remain indispensable in certain production steps. A key challenge lies in ensuring that the biocarbon meets stringent quality requirements, particularly regarding the removal of critical ash-forming elements, such as potassium (K) and phosphorus (P), commonly found in biomass resources like forest residues and bark. Work involves developing a novel method to remove these elements before the biocarbon enters the steel production process.

5 Nov - Understanding interaction between the DRI-based-EAF slag and the biochars

📅 5 november 2025 kl. 10:15–11:00 på Teams
🎤 Lena Sundqvist-Öqvist & Gangadharan Seenivasan
💡 The seminar discusses how different biochars interact with DRI-based EAF slags compared to anthracite. Using thermal and microstructural analyses, the study evaluates performance and slag reduction characteristics, supporting fossil-free carbon use.

12 Nov - Exploring future use of hydrogen in the steel industry

📅 1 november 2025 kl. 10:15–11:00 på Teams
🎤 Mikael Larsson & Malin Blomqvist
💡 This initiative explores various applications where hydrogen plays a critical role, focusing on key challenges in process development and industrial implementation. The scope includes the use of hydrogen in electric arc furnaces and its integration into heating furnaces. It also examines how hydrogen can contribute to the forestry value chain by enabling the production of renewable hydrocarbons, which can be used in both electric arc and heating furnaces.
