Electrode for electroslag remelting and process of producing alloy using the same

摘要

An object of the invention is to provide an ingot having improvement of and a prevention of occurrence of segregation when electroslag remelting method is used for producing a large size ingot and a super alloy which is sensitive to segregation. 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.
