The steam turbine main shaft serves as the core load-bearing rotating component of the entire turbine unit. Assembled with turbine disks, impellers, and coupling hubs, it transmits power from turbine rotors to generators or driven machinery while withstanding significant torque, bending loads, alternating thermal stress, and vibration. Material quality, forging integrity, and machining precision directly determine the turbine's safety, stability, and service life.
We provide fully customized manufacturing solutions for turbine main shafts, covering applications in large thermal power turbines, medium and small industrial turbines, waste heat turbines, back-pressure turbines, and condensing turbines. Our production includes integral forged main shafts and extended composite main shafts manufactured strictly according to customer drawings and power industry standards. Services support both new unit manufacturing and overhaul replacement, with optional Stellite hardfacing on shaft journal and sealing areas.
30Cr2Ni4MoV, 25Cr2MoV, 42CrMo, 34CrNiMo6, and other high-strength dedicated rotor alloy steels. Material selection depends on operating temperature, rotating speed, torque, and medium conditions.
Utilize qualified heavy forgings with standardized multi-stage heat treatment for uniform grain distribution, excellent toughness, creep resistance, and fatigue resistance, effectively preventing crack risks under long-term high-speed rotation and alternating loads.
Precision turning and grinding ensure low concentricity error and stable dimensional accuracy of shaft journals, reducing vibration during operation, protecting bearing bushes, and extending the service cycle of the entire unit.
Custom production based on customer drawings with various overall lengths, shaft diameters, wheel fitting positions, and connection flange forms. We also provide structural optimization schemes for old turbine transformation projects.
Full set of certification files including raw material test reports, forging records, heat treatment curves, machining inspection data, NDT certificates, and dynamic balancing reports, meeting international power industry standards.
Suitable for power generation turbines, waste heat utilization turbines, and mechanical drive turbines widely used in chemical industry, metallurgy, and papermaking applications.
