ABSTRACT:
An object of the present invention is to provide an ingot wherein occurrence is prevented when an electroslag remelting method is used for producing a large ingot and which a super alloy is sensitive to segragation. According to the present invention, the electrode for electroslag remelting method has a hole formed along an axial direction in the core of an electrode. Therefore, the molten pool is made shallow so that flat and segregation is prevented from occurring. Consequently, an ESR ingot of good quality is accomplished with an excellent surface and is free from segregation. Moreover, an electrode melting rate is increasing and efficiency is improved.
