Title:
ARC MELTING FACILITY, AND METHOD FOR MANUFACTURING MOLTEN METAL USING THE ARC MELTING FACILITY
Document Type and Number:
WIPO Patent Application WO/2011/024982
Kind Code:
A1
Abstract:
In order to maintain molten metal in an arc furnace in a stable state by detecting a change in the state of an iron source supplied into the arc furnace when the iron source is continuously supplied to the furnace and melted, provided is an arc melting facility (22) provided with a melting chamber (1) for melting an iron source (20) by arc discharge generated from an electrode (2), and an iron source supply device (8) for continuously supplying the iron source to the melting chamber, the arc melting facility being characterized by comprising a state change detection unit (12a, 12b, 12c) for detecting a change in the state of the melting chamber when the arc discharge is generated from the electrode, and a control device (6) for adjusting the supply speed when the iron source is supplied to the melting chamber by the iron source supply device on the basis of the result of detection by the state change detection unit.
