Manufacturing Record
A quenched-and-tempered rotor engineered for centrifugal force, alternating stress and high-temperature thermal-power operation.
Engineering case
Component application, material and performance requirements are translated into defined manufacturing controls and documented verification.
Thermal, combined-cycle and biomass power units
34CrMo1A alloy steel
For Thermal, combined-cycle and biomass power units, the 34CrMo1A Thermal-Power Rotor must use 34CrMo1A alloy steel at project-specific dimensions and weight while meeting Tensile strength >= 980 MPa; Yield strength >= 830 MPa; Elongation >= 12%; 260-300 HBW. The engineering challenge is coordinated control of metal flow, section uniformity and internal integrity.
The forming strategy controls metal flow, section uniformity and internal integrity. Heating practice, deformation sequence, forging reduction, heat treatment and machining allowance are coordinated with defined material, dimensional, NDT and property release points.
Delivery basis: Machined condition. Tensile strength >= 980 MPa; Yield strength >= 830 MPa; Elongation >= 12%; 260-300 HBW are incorporated into the project inspection plan, with final inspection records and the quality dossier supporting acceptance and release.
Spectrometric chemistry verification with elemental accuracy of +/-0.001%
UT and MT for internal and surface integrity
Mechanical testing up to the approved rotor specification
Material certificate and heat/lot traceability
Heat-treatment and inspection records
Final dimensional report and release dossier
