Production process and method for industrial pure iron

The invention belongs to the technical field of metallurgy, and relates to a production process and method for industrial pure iron. The production process comprises four steps of direct reduction, electric furnace smelting, external refining and molten steel forming, specifically, raw materials such as vanadium-titanium iron concentrate, a binder, and a reducing agent are selectively reduced in adirect reduction device to obtain vanadium-titanium metalized pellets, the vanadium-titanium metalized pellets are heated and melted in an electric furnace smelting device firstly, vanadium slag andmolten separated liquid steel are obtained by controlling the melting separation process, and then decarburization heating of the molten separated liquid steel is achieved through slagging smelting toobtain high-purity liquid steel; and the high-purity liquid steel is subjected to desulfurization and vacuum decarburization treatment in an external refining device, and the refined qualified liquidsteel is subjected to conti
