Zusammenfassung: | Provided is a method of manufacturing molten iron by charging a raw material and a reducing material into a melting and gasifying furnace, blowing oxygen to manufacture molten iron, and supplying a reducing gas to a reducing furnace to reduce iron ore, comprises: a raw material preparation step of preparing a raw material; a reducing material preparation step of preparing a first reducing material which is pre-dried and a second reducing material which is not pre-dried without being mixed with each other as a reducing material; and a charging step of charging the raw material and the reducing material into the melting and gasifying furnace, wherein the charging step comprises a separation charging step of charging the first reducing material and the second reducing material into the melting and gasifying furnace without being mixed with each other, for improving the coal charging structure in the melting and gasifying furnace to stabilize the flow of the molten material and the reducing gas. |
