METHOD OF CONTROLLING TECHNOLOGY OF ELECTRIC-ARC REDUCTION SMELTING Russian patent published in 2006 - IPC H05B7/148 F27B3/08 F27B3/28

Abstract RU 2268556 C1

FIELD: metallurgy.

SUBSTANCE: method of controlling technology of electric-arc reduction smelting has adjustment of charge, electric and electrode modes due to periodical change in excess or deficiency of carbon in charge, switch of steps of voltage, and electrode switch and transfer. Electric parameters of state of phases and areas of working space of charge, arc and melt are determined as well as deviation of the parameters from preset ones for current moment of reduction cycle. Charge, electric and electrode modes are adjusted accordingly to found deviation.

EFFECT: improved productivity of furnace; reduced energy consumption.
