SMELTING METHOD AND SMELTING DEVICE FOR PROCESSING IRON-BASED POLYMETALLIC MINERAL MATERIALS USING SHORT PROCESS

摘要

Disclosed is a smelting method and smelting device for processing an iron-based polymetallic mineral using a short process. The smelting system used in the smelting method includes a bath smelting device. A dividing wall (30) is provided in the bath of the bath smelting device. The dividing wall divides the bath into a melting zone (10) and an electrothermal reduction zone (20), and the bottom of the melting zone (10) is connected to the electrothermal reduction zone (20). The smelting method includes transporting the iron-based polymetallic minerals, fuel, flux and oxygen-enriched air to the melting zone, and performing melting and partial reduction to obtain molten liquid; transporting the molten liquid and a reducing agent to the electrothermal reduction zone and performing reduction smelting treatment to obtain vanadium-containing molten iron and titanium slag.
