PROCESS OF REFINING CARBON-CONTAINING FERROSILICIUM

FIELD: metallurgy. ^ SUBSTANCE: invention relates to processes of decarbonizing ferrosilicium in ore-thermal furnaces. Smelted ferrosilicium melt is treated by feeding it to silica-containing material jet at a rate of 0.5 to 12 kg/min per 1 t melt and at treatment time within a range of 5 to 20 min....

Beschreibung
Zusammenfassung:	FIELD: metallurgy. ^ SUBSTANCE: invention relates to processes of decarbonizing ferrosilicium in ore-thermal furnaces. Smelted ferrosilicium melt is treated by feeding it to silica-containing material jet at a rate of 0.5 to 12 kg/min per 1 t melt and at treatment time within a range of 5 to 20 min. Silica-containing material is, namely, silica-containing dust from dry cloth gas treatment ovens serving for ferrosilicium and/or silicon smelting. ^ EFFECT: reduced silicon combustion and power consumption and increased economical efficiency of ferrosilicium refinement process. ^ 2 cl, 1 tbl
