FIELD: metallurgy.
SUBSTANCE: method comprises steps of sampling intensity of constant magnetic field of solenoid supplied from HF-generator and electric current of arc discharge; inspecting natural frequency of crystallizer during melting process and changing magnetic field intensity according to given mathematical expression; lowering electric current of electric arc discharge and increasing power of HF-generator in proportion to change of natural frequency of crystallizer poured with melt during melting process.
EFFECT: enhanced quality of metal, lowered electric energy consumption.
