An extruded rotor, a steam turbine having an extruded rotor and a method for producing an extruded rotor

摘要

A steam turbine, a rotor and a method for making an extruded rotor (300) are disclosed as having a rotor bore (200) formed of an extruded high temperature alloy. The method includes providing a high temperature alloy, melting the high temperature alloy, extruding the high temperature alloy to form a bore (200), and forming the bore (200) into a rotor (300).
