Targeted customization for 350 MW control-stage severe working conditions. Customize airfoil profile, fork-type blade root, dimensional tolerance and surface strengthening treatment per drawings or renovation schemes. Perfectly match original rotor wheel groove, minimizing on-site modification workload.

• 3D-Aerodynamic Optimization for Wide-Range Variable-Load Operation
  Multi-stage CFD simulation optimizes blade profile for control-stage partial-admission characteristics. Effectively reduce flow loss and improve control-stage efficiency under wide operating load range.
• Excellent High-Temperature Strength & Anti-Fatigue Performance
  Premium heat-resistant alloy material with outstanding resistance against high-temperature creep, steam oxidation, thermal fatigue and solid-particle erosion. Reliable performance under frequent start-stop, peak-shaving and variable-load operation.
• High-Precision Machined Robust Blade Root
  Strict tolerance control for fork-type blade root, realizing stable and reliable blade-rotor connection. Good vibration-suppression performance, avoiding resonance risk and lowering high-speed rotating fatigue risk for long-term stable operation.
• Strict Full-Process Quality Assurance
  Raw-material certification, multi-item NDT non-destructive testing, dimensional inspection and surface integrity verification. Fully comply with large-power-generation equipment standards for both base-load and cycling-mode service.
• Superior Lifecycle Economic Benefits
  Improve unit availability, reduce unplanned outage risks, extend blade service cycle, and cut maintenance frequency and overall OPEX for 350 MW power-generation assets.
