Manufacturing a steam turbine rotor is a meticulous process. It commences with the selection of high-grade steel alloys renowned for their strength and heat resistance.
Through forging, the raw material is shaped and aligned, ensuring optimal structural integrity. Precision machining follows, utilizing CNC technology to carve out intricate features. Dynamic balancing prevents undue stress and vibrations.
Heat treatment enhances mechanical properties, while blade attachment demands precise welding or fastening. Surface treatments like nitriding fortify against corrosion. Rigorous quality checks, including non-destructive testing, guarantee flawlessness. Post-inspection, the rotor is assembled into the turbine.
Comprehensive testing for vibration, temperature, pressure, and speed culminates in a meticulously crafted rotor, a vital component in the realm of power generation.
