<p>Provided is a process for producing molten iron through the efficient reduction of iron oxides having various chemical compositions and various shapes or through the efficient melting of scrap iron or reduced iron having various shapes and various chemical compositions. The process is intended to be used in the case where the amount of iron necessary per furnace is not so large as in blast furnace processes. The process for molten-iron production comprises: a step in which carbon-containing molten iron is fed to a container; a step in which the molten iron is heated by the heat of combustion reaction of a gaseous mixture of a fuel gas and a combustion-supporting gas, and the heat is stored therein; and a step in which a ferrous material comprising iron oxides and/or scrap iron and a carbon source are added to the molten iron in which heat has been stored by the heating, whereby the ferrous material is converted to molten iron.</p> |
