5th European Academic Symposium on EAF Steelmaking (EASES) in Oulu

This year the Euro­pean Aca­de­mic Sym­po­si­um on EAF Steel­ma­king (EASES) took place in Oulu, Fin­land. Alre­a­dy for the fifth time, PhD stu­dents, post­docs and other sci­en­tists from Euro­pean uni­ver­si­ties came tog­e­ther from July 05–07, 2023, to pre­sent and dis­cuss cur­rent results of their rese­arch pro­jects on elec­tric steel­ma­king. The IOB was repre­sen­ted as offi­ci­al co-orga­ni­zer by Tho­mas Ech­ter­hof, Sid­dha­rth Nach­an­kar and Amit Sharma.

The sym­po­si­um star­ted on Mon­day, July 05, 2023, with a mee­ting at the famous Tori­pol­li­isi sta­tue in the cen­ter of Oulu, fol­lo­wed by a city tour and an infor­mal din­ner. The next two days were fil­led with a pro­gram of a total of 29 lec­tures topics rela­ted to elec­tric steel­ma­king in the elec­tric arc fur­nace. The lec­tures on July 06 focu­sed on pro­cess con­trol and sen­sor tech­no­lo­gy as well as pro­cess mode­ling and simu­la­ti­on. The pro­gram on July 07 included ses­si­ons on slag and by-pro­ducts, pro­ces­sing and valo­riza­ti­on, reduc­tion of CO2 emis­si­ons and envi­ron­men­tal impact, and fos­sil-free raw mate­ri­als in electrolysis.

As part of the pro­gram, the near­ly 60 par­ti­ci­pan­ts also took part in a labo­ra­to­ry tour of the Uni­ver­si­ty of Oulu’s Pro­cess Metall­ur­gy Rese­arch Depart­ment, whe­re some of the mel­ting and test­ing equip­ment was pre­sen­ted. The cur­rent rese­arch sta­tus of their work was pre­sen­ted by our col­le­agues in the fol­lo­wing presentations:

  • Deter­mi­na­ti­on of the Hot Heel in an Elec­tric Arc Fur­nace Using Com­pu­ter Visi­on
    Amit Shar­ma, Tho­mas Ech­ter­hof, Her­bert Pfeifer
  • A Review of Ther­mo­dy­na­mic and Kine­tic Models for the beha­vi­or of Nitro­gen in an Elec­tric Arc Fur­nace
    Sid­dha­rth Nach­an­kar, Tho­mas Ech­ter­hof, Her­bert Pfeifer
  • Decre­asing the envi­ron­men­tal impact of the elec­tric steel making pro­cess through imple­men­ta­ti­on of retro­fit­ting solu­ti­ons
    Felix Kai­ser, Tim Rei­chel, Tho­mas Ech­ter­hof, Dia­na Mier, Iñi­go Unamu­no, Her­bert Pfeifer
  • Appli­ca­ti­on of Hydro­gen-Fue­led Bur­ners in Elec­tric Arc Fur­naces
    Lil­ly Schüt­ten­sack, Tho­mas Ech­ter­hof, Her­bert Pfeifer

One of the high­lights of the con­fe­rence was the din­ner on Tues­day. It was held at Patis­se­rie Ravin­to­la Rau­ha­la and gave a fur­ther insight into aca­de­mic life at the Uni­ver­si­ty of Oulu. During the din­ner, the pri­ze for the best paper was award­ed to Davi­de Mom­bel­li from Poli­tec­ni­co di Mila­no. In addi­ti­on, the best paper by a doc­to­ral can­di­da­te went to our col­le­ague Lil­ly Schüt­ten­sack for her paper on the “Appli­ca­ti­on of Hydro­gen-Fue­led Bur­ners in Elec­tric Arc Fur­naces”. The din­ner was roun­ded off by a per­for­mance of the band Teek­ka­ri­tor­vet, com­po­sed of stu­dents from the uni­ver­si­ty, who per­for­med a num­ber of jazz classics.

At the end of the con­fe­rence, co-orga­ni­zer Tho­mas Ech­ter­hof than­ked ever­yo­ne who con­tri­bu­ted to a suc­cessful EASES 2023. Spe­cial thanks went to Ville-Valt­te­ri Visu­ri and his col­le­agues from the Uni­ver­si­ty of Oulu for hos­ting EASES 2023 and for the excel­lent orga­niza­ti­on of the event. Final­ly, it was announ­ced that the Uni­ver­si­ty of Ljublja­na in Slove­nia will host EASES 2025. We are alre­a­dy loo­king for­ward to the sixth symposium!
