Abstract
An electric arc melting facility includes a melting chamber configured to melt a source iron therein by electric arc discharge generated from an electrode, and a source iron feeder configured to continuously feed the source iron to the melting chamber. The facility further includes a state change detector configured to detect a state change of the melting chamber when the electric arc discharge is generated from the electrode, and a controller configured to adjust a feed rate at which the source iron feeder feeds the source iron to the melting chamber, based on a detection result of the state change detectors.
