Title:

ARC MELTING FURNACE DEVICE

Document Type and Number:

WIPO Patent Application WO/2011/155155

Kind Code:

A1

Abstract:

Disclosed is an arc melting furnace device that reduces the burden on the operator and the amount of time required to perform work. Said arc melting furnace device (1) is provided with: a housing (2) in which a melting chamber (2a) is formed; a hearth (4) that is installed inside the melting chamber (2a) and has concavities (4a); a heating mechanism (10) that heats and melts a metal material loaded into the concavities (4), thereby creating alloy ingots; a flipping member (23) that is rotatably supported by support members (21) provided vertically inside the melting chamber (2a); and auxiliary flipping members (24) that are provided above the top edges of the concavities (4a) and act as springs. The outer edges of the flipping member (23) rotate and move along the inner surfaces of concavities (4a), thereby lifting the alloy ingots created in said concavities (4a) above the hearth (4) and rotating said ingots. The auxiliary flipping members (24) are designed so as to bend a prescribed amount upon contact with alloy ingots, and by returning from the bent state to the original state, the auxiliary flipping members bias said alloy ingots and cause the alloy ingots to fall into the concavities (4a).
