Document Type and Number:
Japanese Patent JP5606320
Kind Code:
B2
Abstract:
The object of the present invention is to provide a process for producing molten iron through the efficient reduction of iron oxide 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 being used in cases where the amount of iron necessary per furnace is not so large as in blast furnace processes. Specifically, the present invention provides a process for producing molten iron comprising the steps of: supplying carbon-containing molten iron to a holding container, heating the molten iron using heat of a combustion reaction of a gas mixture containing a fuel gas and a combustion-supporting gas, thereby storing the heat therein, and adding a carbon source and an iron-containing material that contains iron oxide and/or scrap iron to the heated and heat-stored molten iron, thereby converting the iron-containing material to molten iron.
