Abstract
To provide a method for melting metal raw materials, which can melt a large amount of metal raw materials by setting conditions for melting metal raw materials that partially or entirely contain reduced iron using a submerged arc furnace (SAF) and conducting stable current flow. A method for melting metal raw materials using an electric furnace, which contains molten iron, molten slag, metal raw materials, and auxiliary materials in a stacked manner inside the electric furnace and discharges the molten iron and molten slag, and when an electric current is supplied to the molten metal by an arc or via the molten slag and metal raw materials to heat them, the resistivity inside the electric furnace is set to a range of 0.01 to 0.02 (Ω·m).
