Subject aims expressed by acquired skills and competences

- student will be able to compare advantages of top and bottom blown converters - student will be able analyse charge composition by variant of converter, and to describe emerging wastes and possibilities of their treatment - student will be able to characterize the technology of steel and ferro-alloys production under conditions of electric arc/induction furnaces, to describe the arc characteristics, electrodes regulation, work of DC EAF, and new flexible processes in the frame of electro-metallurgy - student will be able to formulate the fundamental physical-chemical processes during the steel and ferro-alloys production in the EAF

Teaching methods

Individual consultations


The subject is focused on study of theoretical and technological aspects of steel production in oxygen converters and electrical arc furnaces including deepening of knowledge in theory an practise area of plain, alloying and stainless steel production and in area of steel production in hybrid and flexible metallurgical units.
