Features & advantages

1. Full-Ring Casting for Large-Diameter Components
The steam turbine partition sleeve features a large diameter and relatively thin wall, making the casting process more demanding than conventional steel castings. Tenfaye applies a full-ring casting process developed from our experience in manufacturing large girth gears, helping improve structural consistency and reduce dimensional deviations caused by segmented casting.
2. Controlled Deformation During Heat Treatment
Thin-wall, large-diameter turbine components are particularly sensitive to deformation during heat treatment. Tenfaye uses dedicated heat treatment procedures, including full-ring heat treatment, to reduce deformation and maintain dimensional stability throughout the manufacturing process.
3. Optimized Foundry Process and Materials
The casting process is developed according to the component's service conditions and inspection requirements. High-quality molding materials are selected for critical areas, including imported chromite sand, to support surface quality and casting stability. Process simulation and production experience are combined to optimize the casting design and process parameters before production.
4. Precision Machining for Large Ring Components
After heat treatment, the partition sleeve undergoes controlled machining procedures from turning to boring and milling. Dedicated machining processes are established for different operations, with experienced personnel responsible for dimensional control. Large vertical lathes and boring and milling machines are available for machining large-diameter components.
5. Suitable for Multi-Model and Batch Production
Steam turbine components often involve multiple models and repeated production requirements. Tenfaye has established dedicated production and machining resources for turbine components, supporting the manufacture of different sizes and specifications while maintaining consistent process control across batch orders.
6. Integrated Manufacturing and Inspection
Tenfaye provides an integrated production process covering casting, heat treatment, machining, finishing and inspection. This reduces the need for multiple external processing stages and allows dimensional and quality control to be followed throughout the manufacturing process.
