As one of the most critical components, the gas turbine nozzle ring must have the characteristics of high temperature and pressure resistance and strong corrosion resistance, and the choice of material is directly related to the service life and mechanical properties of the parts and even the whole engine. Relatively speaking, nickel-based alloys are our best choice, especially inconel625, with its excellent strength and super corrosion resistance and oxidation resistance, becoming our ideal material. This article will describe our company’s precision production process for nozzle rings and the product advantages of the final product.
1. Precision manufacturing process of Inconel 625 nozzle ring
The manufacture of the Inconel 625 nozzle ring is a complex process that typically involves the following steps:
1) Material preparation
- Selection of material: The appropriate Inconel 625 raw material is selected according to the design requirements, usually in the form of bar, sheet or tube.
- Material inspection: to ensure that the material meets the specifications, chemical composition analysis and physical properties test.
2) Preliminary molding
- Heat treatment: Solution treatment of the billet to improve its mechanical properties, usually involving heating to a specific temperature followed by rapid cooling, such as water quenching.
- Cutting: According to the size requirements of the final product, using sawing or laser cutting to cut the blank from the raw material in the desired shape and size.
3) Molding processing
- Forging: For some applications requiring high strength and toughness, further forming may be required by hot or cold forging.
- Machining: Using CNC machine tools and other precision equipment to turn, mill, drill and other operations to achieve the exact size and surface finish requirements.
- Welding: If the design requires it, it may involve welding multiple parts together to form a complete nozzle ring structure. Inconel 625 has good weldability, but attention should be paid to controlling welding parameters to avoid cracks.
4) Precision machining and surface treatment
- Surface treatment: In order to improve the corrosion resistance and surface quality, polishing, sandblasting, electroplating and other methods can be used for surface treatment.
- Finishing: After the initial molding is completed, fine machining is required to ensure that all dimensions are within tolerances.
5) Quality inspection
- Non-destructive testing: Use X-ray, ultrasonic and other technology to check internal defects.
- Dimensional inspection: dimensional accuracy inspection of finished products is carried out by using coordinate measuring machine (CMM) and other tools.
- Performance test: According to the specific application requirements, the pressure resistance, temperature resistance, fatigue life and other aspects of the test.
6) Packaging and delivery
- Delivery: Delivery of the finished product to the designated location.
- Cleaning: Remove surface oil and other residue.
- Packing: properly pack according to customer’s requirements to prevent damage during transportation.
