Smelting device and smelting method for processing iron-based multi-metal mineral material through short process

The invention provides a smelting method and a smelting device for processing an iron-based multi-metal mineral material through a short process. The smelting system adopted in the smelting method comprises a molten pool smelting device, wherein a partition wall is arranged in a molten pool of the molten pool smelting device so as to divide the molten pool into a melting area and an electric heating reduction area, and the bottom of the melting area communicates with the electric heating reduction area. The smelting method comprises the following steps that the iron-based multi-metal mineral material, fuel, a fusing agent and oxygen-enriched air are conveyed into the melting area for melting and partial reducing so as to obtain a molten liquid; and the molten liquid and a reducing agent are conveyed to the electric heating reduction area for reduction smelting treatment to obtain molten iron containing a vanadium element and titanium slag. According to the method and the device, on onehand, the occupied area
