Overview

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 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 interests

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.

A portfolio of research interests is given below:
  1. argon-oxygen decarburisation
  2. blast furnace
  3. basic oxygen furnace
  4. composition adjustment by sealed argon bubbling - oxygen blowing
  5. ferrochrome converter
  6. hot metal desulphurisation
  7. inclusions
  8. ladle
  9. vacuum tank degassing

Current research topics

Research activities as a researcher as of December 2018:
  1. Mathematical modelling of hot metal desulphurisation
  2. Physical modelling of hot metal desulphurisation
Research co-operation is conducted primarily with Aalto University, RWTH Aachen University, SSAB Europe Oy and Outokumpu Stainless Oy. On-going co-operative topics are listed below:
  1. Vibration-based measurements in the vacuum tank degassing and BOF processes.
  2. Computational fluid dynamics modelling of gas-injection in ladles.
  3. Experimental study of sulphur pick-up in hot metal desulphurisation.
  4. Further development of a continuous casting simulator and related thermodynamic database.

Service to academic community

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