Research topics

My research focuses on process metallurgy; a discipline, which studies the refining of molten metals. Global megatrends, such as urbanisation and climate change, require extensive research on new types of steels and new methods to manufacture them. In the last few decades, great progress has been made in reducing the environmental load of steel per tons produced. This has been enabled to great extent by the use of modern computational methods, new measurement technology and new operating practices.

In my research work, I work mostly with chemical thermodynamics, chemical kinetics and transport phenomena in converter and ladle metallurgy of steelmaking. I conduct and instruct research with a boad range of methods, including mathematical modelling, physical modelling, computational thermodynamics modelling, computational fluid dynamics modelling, online measurements and high-temperature experiments.

Current research topics

Own research activities:
  • Mathematical modelling of hot metal desulphurisation
  • Physical modelling of hot metal desulphurisation
  • Refractory wear in ferrochrome converters
  • Reuse of used refractory materials
On-going co-operative research:
  • Computational fluid dynamics modelling of hot metal desulphurisation
  • Data-driven modelling of desulphurisation using calcium carbide
  • Quality indices in continuous casting of steel
  • Thermodynamics of steel solidification
  • Vibration-based measurements in the vacuum tank degassing and BOF processes
The research is often made in cooperation with companies and foreign research institutes. So far, I have participated in joint research with Aalto University (Finland), Luxmet Oy (Finland), Northeastern University (China), RWTH Aachen University (Germany), SSAB Europe Oy (Finland), Outokumpu Stainless Oy (Finland) and Weierstraß-Institut für Angewandte Analysis und Stochastik (Germany).

Service to academic community

I frequently serve as a peer-reviewer for academic journals, such as Applied Mathematical Modelling (Elsevier), Entropy (MDPI), Metallurgical and Materials Transactions B (Springer), Metals (MDPI), Steel Research International (Wiley-WCH), and Vacuum (MPDI). I've also served as a session chairman at European Steel Technology and Application Days 2017.
