OverviewMy 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 term. In the last few decades, great progress has been made in reducing the environmental load of steel per tons produced. Several factors have contributed to this aim, and include the rise of modern computational models, new measurement technology and accumulating knowledge of the underlying phenomena.

Research interestsIn 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.
A portfolio of research interests is given below:
- argon-oxygen decarburisation
- blast furnace
- basic oxygen furnace
- composition adjustment by sealed argon bubbling - oxygen blowing
- ferrochrome converter
- hot metal desulphurisation
- vacuum tank degassing
Current research topicsResearch activities as a researcher as of December 2018:
- Mathematical modelling of hot metal desulphurisation
- Physical modelling of hot metal desulphurisation
- Vibration-based measurements in the vacuum tank degassing and BOF processes.
- Computational fluid dynamics modelling of gas-injection in ladles.
- Experimental study of sulphur pick-up in hot metal desulphurisation.
- Further development of a continuous casting simulator and related thermodynamic database.
