Beschreibung
Zusammenfassung:	The invention relates to the field of ferrous metallurgy. The method for ferroalloys manufacture in an ore-smelting furnace involves charging of charge materials into the furnace bath, smelting of an alloy with set electric and thermal modes which are corrected by displacement of electrodes and switching of voltage degrees of the transformer, thus equalize thermal modes under each electrode, reasoning from values temperature on a furnace mantle opposite to electrodes on the distance of 0.30-0.35 heights of a furnace bath from its buttom, the discharge of liquid alloy from the furnace, at that melting is carried out at the determined ratio of electric parameters of a mode with calculation thermal load under the electrodes deregulation directly after the start-up of the furnace in manufacture. The invention allows to lead melting at optimum thermal load which is fed to the electrodes of an ore-smelting furnace.
