Abstract

To provide a method for melting a metal raw material that can perform a process of melting a large amount of metal raw material by appropriately setting the conditions for performing a process of melting a metal raw material composed partially or entirely of reduced iron, using a submerged arc furnace (SAF), and by passing a stable current. Specifically, provided is a method for melting a metal raw material using an electric furnace comprising accommodating molten iron, molten slag, a metal raw material, and an auxiliary raw material in stacked layers in the electric furnace, and discharging the molten iron and the molten slag, in which the resistivity within the electric furnace is set within a range of 0.01 to 0.02 (Ω·m) when a current is supplied to the molten metal to heat the molten metal through an arc or via the molten slag and the metal raw material.
