  • Publication number: 20080142188
    Abstract: A method for producing a consumable electrode for remelting and an end face cutter for use in the method in which an ingot made in a consumable electrode arc remelting process is used as a material for the consumable electrode, are characterized in that said ingot can be set so that its centerline axis in a longitudinal direction lies horizontally and an end face of said ingot is machined by milling to be flat, the end face being connected with a stub, the stub holding the consumable electrode. In melting the consumable electrode, the present invention makes it easier to machine the bottom face of ingot that is to be mounted onto the stub or to perform conditioning such as cleaning the surface, which results in cutting man-hours and processing steps required for those operations and improving a product yield, thus enabling it to be widely used as a method for producing an ingot by the VAR process and contributing to the development of the relevant technology.
