Advanced Melt Metallurgy

Demands for advanced steels have increased the complexity of secondary metallurgy. This requires very good control of steelmaking processes. To ensure fast implementation of a new steel grade to profitable production a holistic model of secondary processes with fundamental based sub-models are needed. The aim of this project is
a) to treat the set of holistic process oriented models describing dominating phenomena (e.g. behavior of supersonic oxygen jet, foaming etc) similar to all secondary metallurgy process units and
b) to develop new concepts to produce advanced steels and ferroalloys with secondary metallurgy units and simulate process procedures in case specific studies (vacuum, AOD, CAS-OB and BOF processes).

Participants of the project are Rautaruukki Metals Oy, Outokumpu Stainless Oy, Process Metallurgy and Heat and Mass Transfer laboratories of University of Oulu, Aalto University and VTT. Total budget of research partners is 2,5 Meuro.
