Custom Design Alloy Steel Steam Turbine Rotor with Precision Control for Power Plants
Product Details
The steam turbine rotor serves as the core rotating component of steam turbine equipment, transforming steam thermal energy into rotational mechanical power. Our fully customized steam turbine rotors are tailor-engineered to match diverse working conditions, unit parameters, and client design drawings.
We deliver one-stop customized solutions including design optimization, alloy steel smelting, heavy open-die forging, precise heat treatment, multi-axis CNC finishing, dynamic balancing, and full non-destructive testing. Each rotor is manufactured strictly in accordance with ASTM, DIN, GB, and API industrial standards to guarantee long-cycle safe operation under extreme temperature, pressure, centrifugal force, and alternating thermal loads.
Develop rotor solutions based on customer drawings, steam parameters, rotating speed, power rating, and layout requirements. Support single-flow, double-flow, welded rotor, and monoblock solid forging structures.
Select premium creep-resistant alloy steels upon demand: 25Cr2Ni4MoV, 30Cr2Ni2Mo, 34CrNi3Mo, 1.6985 (28CrMoNiV4-9), 9-12Cr heat-resistant steel, and other high-temperature alloys suitable for subcritical, supercritical, and ultra-supercritical steam service conditions.
Cover small industrial turbine rotors to large utility-grade rotors: maximum workpiece weight up to 150 tons; machinable length up to 18 meters; customized rotor diameter, journal size, wheel groove structure, blade mounting grooves, and sealing geometry.
Precision turning, milling, grinding, surface strengthening, stress relief, high-speed dynamic balancing, anti-corrosion coating, and blade installation service.
Vacuum refined ingots + controlled hot open-die forging to realize continuous, streamline grain flow. Effectively reduce internal porosity, segregation, and inclusions, delivering superior toughness, fatigue resistance, and high-temperature creep performance.
Computer-controlled quenching & tempering heat treatment ensures stable mechanical properties. Advanced heavy-duty CNC machining maintains tight dimensional tolerances; precision dynamic balancing minimizes vibration during high-speed rotation.
Full-range non-destructive testing (UT, MT, PT) implemented after forging, heat treatment, and finishing. Complete material certificates, mechanical test reports, and inspection records are supplied for every rotor.
Avoid over-design or insufficient performance caused by standardized products. We adjust material grade, structural strength, and machining scheme according to actual startup-shutdown frequency, temperature fluctuation, and medium environment to extend service life and lower maintenance cost.
Our engineering team provides front-end technical consultation, design review, manufacturing progress tracking, and on-site technical cooperation. We also support rotor refurbishment, retrofitting, and spare rotor customization for old unit upgrade projects.
