Possibility of a wide choice of original charge and variation of oxidation potential in melting process makes the electric arc furnace (EAF) a general-purpose unit in foundries. Energy-intensive classical technology with insufficient specific power of the transformer, irregular operation with forced downtime predetermine a low energy efficiency of foundry class furnaces [1,2]. Flat and shallow bath of the EAF enhances the problem.
