METHOD FOR REGULATION OF TEMPERATURE CONDITIONS IN CONTINUOUS FURNACE FOR MELTING SULFIDE ORES AND CONCENTRATES OF NONFERROUS METALS Russian patent published in 1994 - IPC

Abstract RU 2020168 C1

FIELD: nonferrous metallurgy. SUBSTANCE: method includes charging of sulfide raw material through furnace arch, uniform supply of oxygen over furnace length into melt through lances, and measurement of melt temperature t_ch in zone of charge. During feed of raw material, melt cooling t_cool=t_opt-t_ch is determined and with ratio t_cool:t_opt>0,08, oxygen is additionally fed through lances located in charge zone to restore optimal temperature t_opt. EFFECT: higher efficiency of furnace and prevention of formation of wall accretion.
