FIELD: metallurgy.
SUBSTANCE: invention refers to metallurgy and can be used in obtainment of silicon, ferrous and non-ferrous metal alloys in ore-thermal electric furnaces after repair, equipped with reactive power compensation aggregates. After halts for repair, a furnace for ore melting in the presence of reducing agents and reactive power compensation aggregate are activated simultaneously, and furnace power factor is raised gradually by activation of capacitor bank sections of the reactive power compensation aggregate with 2-8 hour interval for each boost of power factor, and the number of activated capacitor bank sections is gradually increased from 2 to 12.
EFFECT: reduced loss of active power of furnace during power gain after long-term standstills, resulting in increased performance of furnace.
