PROBLEM TO BE SOLVED: To produce molten iron in an electric furnace by melting a cold iron source to produce molten iron without using special equipment or an expensive heat source, as compared with a conventional method. SOLUTION: In an electric furnace provided with a melting chamber 1 for melting a cold iron source by arc heating and a preheating chamber 2 for preheating the cold iron source supplied to the melting chamber 1, the exhaust gas generated in the melting chamber 1 To preheat the cold iron source by passing it through the preheating chamber 2 to which the cold iron source is supplied, supply the preheated cold iron source to the melting chamber 1, and melt in the melting chamber 1 to obtain molten iron. Therefore, waste oil is mixed with the cold iron source, and the cold iron source mixed with the waste oil is preheated in the preheating chamber 2. Since heat can be added to the cold iron source and the molten iron side by the waste oil mixed with the cold iron source, the electric power basic unit for melting the cold iron source to obtain molten iron can be reduced.
