Research group: Process Metallurgy
Research subject: Application of Timegated Raman spectroscopy for characterising synthetic non-metallic inclusions
Researcher profile: Coming soon
Who are you?
I am Francis Gyakwaa, metallurgist by profession, currently with Process Metallurgy Research Unit under the Faculty of Science and Technology, University of Oulu.
Where you come from?
I was born in Ghana, West Africa and a Ghanaian citizen.
What you have done before coming to Oulu?
Before coming to Oulu, I had BSc. Mineral engineering from the University of Mines and Technology - Tarkwa, Ghana. I have working experience in the gold mining industry in Ghana as a metallurgist. My current highest level is Master of Science in Engineering- Applied Measurement Science from the University of Tartu, Estonia.
Why did you decide to come to Oulu?
My decision to move to Oulu was based on the innovative and very productive process metallurgy research group within the University of Oulu. So far, I am glad to say enjoy working with this research unit.
What is the name of your research project?
Characterisation of non-metallic inclusions in iron and steelmaking in metallurgical processes using Raman spectroscopy.
What is the expected main outcome from your research project
The increasing use of metals such as iron and steel in industrial, constructional work and everyday life, therefore demand high quality metals. Assessing steel cleanliness and quality depends on the amount of non-metallic inclusions as because it is known to pose some quality challenges on its properties such as fatigue, toughness and other product defects. To achieve an efficient and continuous improvement in metallurgical processes, my research is aim using a versatile and non-destructive approach Raman spectroscopy for characterisation of non-metallic inclusion. My research project will aim to contribute to ensuring quality iron and steel products as we use these metals in places such as our home, offices and constructional works.
What you would like to do after you have got PhD degree?
After successful completion of my doctoral studies, my interest is to advance in the current research field, related metallurgical sectors or take up a position any industrial or quality monitoring sector. I think the success of this research project will place me in a better position to apply the knowledge and skills innovatively in any industrial and research activity related to this research project.
What I4FUTURE program has so far given to you? What has been good? Have you missed something?
I think the I4FUTURE program has been well structured since its programs members are from interdisciplinary fields of research which make it quite easy for have some basic knowledge of other research works. Additionally, the programs designed such intensive courses and coffee visit to different research unit makes the I4FUTURE very interactive.
What kind of the atmosphere /weather in Oulu has been in your opinion?
The atmosphere in Oulu in terms of the weather, I will say is on balance, while I enjoy seeing snow during winter, it is also challenging at times getting used to the freezing temperatures.
Have you already published results? If yes, where?
Currently, I have one published article in the Iron and steel institute of Japan, ISIJ International. The title is “Applicability of Time-Gated Raman Spectroscopy in the Characterisation of Calcium-Aluminate Inclusions” available in https://doi.org/10.2355/isijinternational.ISIJINT-2019-122
On my own words
I am with Process Metallurgy Research Unit under Faculty of Science and Technology. ‘Online in situ measurement of slag composition in metallurgical processes’ is my research topic and Luxmet Oy and TimeGate Oy partner organizations. It duration is from January, 2017 to January, 2021.
I had BSc. Mineral engineering from University of Mines and Technology - Tarkwa, Ghana with three work experience in gold mining industry as a metallurgy and Master of Science in Engineering- Applied Measurement Science from University of Tartu, Estonia.
My expectation for this program is to develop an innovative measurement procedure for on-line in situ analysis of slag composition characterisation applicable to the metallurgical industries.
