The quality control of circular forging parts is a key link to ensure their quality and performance. The following are some commonly used quality control measures:
1. Quality control of raw materials: Select high-quality raw materials and conduct quality inspections to ensure that the quality of raw materials meets the requirements.
2. Forging quality control: During the forging process, process parameters such as temperature, pressure, and time should be controlled to ensure the quality and dimensional accuracy of the forgings. At the same time, defects generated during the forging process should be detected and controlled, such as cracks, pores, inclusions, etc.
3. Quality control of heat treatment: Heat treatment is an important part of the manufacturing of circular forgings, and process parameters such as heating speed, heating temperature, and insulation time should be controlled to ensure the quality and effectiveness of heat treatment. At the same time, defects generated during the heat treatment process should be detected and controlled, such as oxidation, decarburization, deformation, etc.
4. Mechanical processing quality control: For ring forgings that require high precision requirements, mechanical processing should be carried out. During the machining process, process parameters such as cutting speed, cutting depth, and feed rate should be controlled to ensure the quality and accuracy of the machining.
5. Quality control of surface treatment: Surface treatment is a key step in improving the corrosion resistance and aesthetics of circular forgings. The process and quality of surface treatment should be controlled to ensure the effectiveness and uniformity of surface treatment.
6. Quality inspection and control: Conduct quality inspection and control on circular forgings, including visual inspection, dimensional measurement, mechanical performance testing, etc., to ensure that the quality and performance of the final product meet the requirements. At the same time, non-conforming products should be traced and processed to prevent them from entering the market.
Overall, the quality control of circular forging parts requires the full process control from raw materials to the final product, including process parameter control, defect detection and control, quality inspection and control, and other aspects. By implementing strict quality control measures, it is possible to ensure that the quality and performance of circular forging parts meet the requirements, thereby improving the reliability and service life of the products.
