Abstract

The present disclosure relates to a method for manufacturing molten iron for manufacturing stainless steel, comprising: a step of forming a melt pool by charging and melting iron ore in a furnace body using an electric melting furnace comprising the furnace body, an electrode rod generating an arc, a raw material charging unit, a slag tapping port, and a metal tapping port; a step of charging a chrome ore and a nickel ore, a slag modifier, and a reducing agent from an upper part of the electric melting furnace along a central axis of the electrode rod into an arc generation region between a lower end portion of the electrode rod and the melt pool; and a step of reacting the charged chrome ore and nickel ore, slag modifier, and reducing agent with the melt pool to melt and reduce.
