Title:
ARC MELTING EQUIPMENT AND MOLTEN METAL MANUFACTURING METHOD USING ARC MELTING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2011/013726
Kind Code:
A1
Abstract:
Provided is arc melting equipment used for melting an iron source with a high heat efficiency and capable of controlling the supply of the iron source supplied from a preheat chamber to a melting chamber, and also provided is a molten metal operation method using the arc melting equipment. The arc melting equipment (1) comprises a melting chamber (2) for melting an iron source, a shaft-type preheat chamber (4) provided so as to be directly coupled to the melting chamber (2), and an electrode (3). In the arc melting equipment (1), at least part of the bottom surface of the preheat chamber (4) is formed as a sloped bottom surface (7a) having a slope descending toward the melting chamber (2). A shaft front dimension (H) is set to the optimum value for controlling the supply of the iron source. A pushing-out device (6) for moving the iron source in the preheat chamber (4) toward the melting chamber (2) is provided at a lower part of the preheat chamber (4). Driving the pushing-out device (6) allows the iron source to be supplied from the preheat chamber (4) to the melting chamber (2), and stopping the driving of the pushing-out device (6) stops the supply of the iron source supplied from the preheat chamber (4) to the melting chamber (2). The optimum value of the shaft front dimension (H) is set so that for the maximum length (A) of the iron source, the relationship A ≤ H ≤ 4A is satisfied.
