A sectioned rotor, a steam turbine having a sectioned rotor and a method for producing a sectioned rotor

摘要

A sectioned rotor (13) is disclosed that includes a high temperature section (210). The high temperature section (210) includes a first high temperature material section (240), a second high temperature material section (245); and a sectioned high temperature material section (247) formed of a plurality of high temperature material subsection components (248). The sectioned high temperature material section (247) is joined to the first high temperature material section (240) and the second high temperature section (245). The plurality of the high temperature subsection components (248) are independently formed of a nickel-based superalloy. A steam turbine (10) having a sectioned rotor (13) and a method for manufacturing a sectioned rotor (13) are also disclosed.
