Beschreibung
Zusammenfassung:	To reduce production costs by increasing molten iron heating efficiency, a production method using an electric furnace is provided with a preheating chamber, a melting chamber, a cold iron source supporter operable to partition the preheating chamber into a first and a second preheating chamber, an extruder, and a video device operable to observe the second preheating chamber is used, the method including a melting process, a heating process, a preheating process, and a tapping process are performed. In the heating process, heating of the molten iron is started after the cold iron source supporter is closed, and based on the visual information obtained via the video device of the second preheating chamber.
