FIELD: metallurgy.
SUBSTANCE: proposed method comprises feeding power for smelting, feeding working gas via flow channel 8 and directing it by at least of plasma burner 10. Plasma is generated by at least one induction heating coil 18 enveloping said flow channel 8 to form heating zone 17. Proposed furnace comprises at least one heater 6 to supply smelting power. Said heater 6 comprises tubular case 7 that cover flow channel 8. Lengthwise section of tubular case 7 is made similarly to plasma burner 10. Note here it has at last one induction heating coil 18 enveloping said flow channel 8 to form heating zone 17.
EFFECT: lower costs.
