Customize blade airfoil profile, fir-tree root geometry, tip shroud structure, dimensional tolerance and surface protection solution based on OEM drawings or field-measured data. Perfectly match existing rotor assembly, minimize on-site modification workload for spare-part replacement or retrofit projects.
Key Features
Advanced 3D-Optimized Twisted-Blade Aerodynamic Design
Multi-stage CFD simulation minimizes exhaust loss, tip leakage loss and secondary flow loss. Optimized long-blade profile improves LP-stage cycle efficiency, reduces unit heat-rate and coal consumption, enhances exhaust performance under both base-load and deep-peak-shaving operation.
Superior Water-Droplet-Erosion-Resistant Performance
Working in severe wet-steam environment, blades adopt professional anti-erosion treatment on leading edge (Stellite hard-facing / laser hardening / HVOF coating options available). Effectively restrain droplet impact erosion, avoid profile degradation and extend service life of critical long-blades.
High-Strength Fir-Tree Root & Precision Five-Axis Machining
Low-stress fir-tree root structure with strict tolerance control, bears huge centrifugal load during high-speed rotation. Excellent vibration-damping capability, effectively suppress resonance risk; adapt to frequent start-stop and cyclic-load working modes of modern power plants.
Optimized Whole-Lifecycle Economic Value
Improve unit availability, cut unplanned outage risks caused by blade erosion & fatigue damage. Prolong overhaul intervals, reduce maintenance frequency and lifecycle OPEX for your 600 MW power assets.
Performance Benefits
Upgrade your 600 MW steam turbine low-pressure end with our custom-made last-stage moving blades. Achieve higher exhaust-stage efficiency, outstanding anti-erosion capacity and enhanced operational security. Whether you need OEM-equivalent spare parts or performance-improved flow-path renovation solutions, we supply reliable custom-manufactured long rotor blades for large thermal-power facilities.
