Abstract:
An arc-melting apparatus for melting a cold iron source comprising:(a) a melting chamber which is used as a space for melting the cold iron source; (b) a preheating shaft directly connected to an upper part of one side of the melting chamber, to preheat the cold iron source by introducing exhaust gas generated in the melting chamber, wherein the preheating shaft and the melting chamber form an integral structure; (c) an arc electrode for supplying heat for melting the cold iron source in the melting chamber; (d) a cold iron source supply device for supplying the cold iron source to the preheating shaft, so as to continuously maintain the cold iron source in the melting chamber and in the preheating shaft, so that the scraps in the preheating shaft are continuously maintained in contact with the surface of the molting metal in the melting furnace; (e) a tapping portion having a tapping hole, projecting outwardly from the melting chamber; and (f) a tilting device for tilting the melting chamber toward the tapping portion, simultaneously for tilting the preheating shaft toward the tapping portion, by the integral structure.
