FIELD: metallurgy.
SUBSTANCE: procedure for control over electric mode of ore-smelting furnace consists in measuring secondary phase voltage and current of electrodes, in additional recording ratio of active and reactive constituents of phase voltage, in determination of position of maximums of useful power by electrical resistance of active losses and reactive resistance of phase, in determination of power consuming and power saving fields relative to electrical modes, and in changing current of electrodes and voltage to eliminate deviations from maximal useful power.
EFFECT: raised efficiency of electrical furnace and reduced specific consumption of electrical power.
