The turbine rotor is the core rotating component of a turbine, consisting of components such as the main shaft, the impeller, and the moving blades.

The turbine rotor is the core rotating component of a turbine, consisting of components such as the main shaft, the impeller, and the moving blades. Its main function is to convert the thermal energy and kinetic energy of steam into mechanical energy. The main shaft is responsible for supporting and torque transmission, the impeller is used to fix the moving blades, and the moving blades directly withstand the steam impact to achieve energy conversion.

We can produce turbine rotor shaft forging, locating ring forging, seal stop ring, sleeve and maintence ring forgings.

At the heart of the manufacturing process for the steam turbine rotor forging lies a combination of forging, quenching and tempering (Q+T), heat stress treatment (HST), rigorous inspection, and precision machining. Each stage is meticulously controlled to guarantee that the turbine rotor achieves optimal mechanical properties, dimensional accuracy, and structural integrity. The forging process itself involves deforming the raw material under high pressure to produce a dense, uniform grain structure with a forging ratio of ≥3.5, which significantly enhances the strength and fatigue resistance of the turbine rotor. This ensures that the rotor can withstand the intense thermal and mechanical stresses encountered during operation.

The material standards adhered to in the production of this turbine rotor forging are comprehensive and internationally recognized, including EN, ASTM, GB, and ISO specifications. These standards ensure that the materials used not only meet stringent chemical composition requirements but also exhibit superior mechanical properties such as tensile strength, toughness, and resistance to creep and corrosion. By conforming to these global standards, the turbine rotor forging is suitable for deployment in diverse geographic regions and power plant configurations, providing versatility and assurance of quality to end users.

Applications of the steam turbine rotor forging are primarily centered on steam turbines used in power plants, where they play a pivotal role in converting thermal energy from steam into mechanical energy for electricity generation.

Inspection procedures during the manufacturing process are comprehensive and include both non-destructive testing and dimensional verification to detect any internal or surface defects. This ensures that each turbine rotor forging meets stringent quality criteria before proceeding to the final machining phase. Precision machining then refines the component to exact specifications, ensuring perfect alignment and balance which are crucial for the turbine rotor’s optimal performance and longevity.

The steam turbine rotor forging is an indispensable component engineered to meet the highest standards of durability, performance, and safety. With a maximum weight of 70,000 kg, a forging ratio of at least 3.5, and adherence to EN, ASTM, GB, and ISO material standards.
