Tiina Riskilä, Graduate Student at SSAB's Raahe mill

Winter 2015

Tiina Riskilä

How did you end up doing your master thesis for SSAB?
I worked as a Development Engineer Trainee for the summer. Afterwards I was offered a possibility to write my Master Thesis for SSAB. I have studied process metallurgy at the University of Oulu, so SSAB was a natural choice.

Describe the subject of your thesis
In my thesis I researched if it is possible to use coke fines and charcoal in coal blend and how they will affect the quality of the coke. I made small-scale coking experiments with different kinds of coal blends. Using coke fines in coal blend would raise the recycling rate which is indeed a good thing.

What steps did you do during this thesis writing process?
I learned a lot about the coking process and the phenomena of it. After making the research plan I did coking experiments and during the writing process I saw how the theory works in practice.

What was the hardest or most difficult part of the thesis process?
My subject was extensive, which made this as a challenging project. Also staying on schedule was very important.

Who helped you and who did you work with?
My supervisors helped me at SSAB and at the university. I worked also with laboratory employees at the research center and the coking laboratory.

What are you future plans?
First I will graduate and afterwards I hope to I find a job!
