PROCEDURE FOR MELTING STEEL IN ARC STEEL MELTING FURNACE OF THREE PHASE CURRENT Russian patent published in 2011 - IPC C21C5/52

Abstract RU 2420597 C1

FIELD: metallurgy.

SUBSTANCE: procedure for melting steel in arc steel melting furnace of three-phase current consists in melting scrap and in metallised pellets successive supply and melting. Metal pellets are supplied and melted when consumption of electric power reaches 220-230 KWth/t and temperature of bath is 1615-1625°C.

EFFECT: reduced specific consumption of electric power at reduced duration of melt, raised efficiency.
