ABSTRACT:
A process for producing a turbine rotor using an ingot in which segregation is prevented effectively when ESR is used to produce a large-sized ingot. A hole is formed along an axial direction in the core of an electrode. The molten pool is made shallow and flat and segregation is prevented from occurring. Consequently, an ESR ingot of good quality offering an excellent surface is obtainable as it is free from segregation. Moreover, an electrode melting rate is increased and efficiency is improved so that a high quality turbine can be manufactured from the ingot.
