Faculty of Technology, Process Metallurgy

The University of Oulu is a multidisciplinary, international research university, with about 3,600 employees who produce new knowledge based on high-standards research and provide research based education to build a more sustainable, smarter, and more humane world. The University of Oulu community has about 17,000 people in total. Our northern scientific community operates globally and creates conditions for the emergence of innovations.  

We are now looking for a

Doctoral Researcher

in the Process Metallurgy Research Unit at the Faculty of Technology.

The Process Metallurgy Research Unit focuses on pyrometallurgical metal production and other high-temperature processes with the main emphasis on the production of iron, steel, and ferroalloys. Research is executed in close cooperation with the metallurgical industry. MET also has a wide national and international network with leading research institutes and universities working in the field of metallurgy and related disciplines. At the moment, the key areas of research are circular economy and the reduction of carbon dioxide emissions in metal production by hydrogen reduction, electrified processes, and biofuels. The main external funding sources include Business Finland, the Academy of Finland, RFCS funds, and Horizon EU programs.

About the job

The doctoral researcher will work on the project Simulation, Modelling and Monitoring of Plasma and Arc Based Processes for Green Metal Production – PlasmArc4Green. The aim of the PlasmArc4Green is to develop digitalization methods for plasma-based processes that are relevant for the transformation towards CO2 neutral metal production. Specifically, development of new measurement techniques and numerical simulations of arc dynamics for better process control are in the core of the project. Testing and validation of the various methods will be demonstrated with lab-scale and pilot-scale hydrogen plasma smelting reduction (HPSR) experiments.

Doctoral researcher’s work will focus on using optical emission spectroscopy (OES) and plasma images to perform H2-plasma characterization. The work includes laboratory and pilot-scale experiments in collaboration with the project’s partners. Due to the vast amount of data that will be generated, part of the work will be to test various statistical data analysis methods and machine learning for efficient data analysis (e.g. regression analysis and image recognition). Based on the OES, image, and reactor data, the doctoral researcher will

  1. use (physics-based) plasma characterization to create a deeper understanding of the HPSR process
  2. find out how the material’s reduction/metallization degree can be assessed from the data
  3. create analysis algorithms, to use them for on-line (real-time) analysis
  4. create and provide data for HPSR process model development
