Ring forgings are precision and high-performance components that are widely used in aerospace, automotive, machinery, and other industries. In the manufacturing process of ring forgings, there are many common problems that, if not addressed, may affect the quality and performance of the product. This article will introduce the common problems and solutions in the manufacturing process of ring forgings.
Cracks
Cracking is one of the most common problems in the production process of ring forgings. The reason for its occurrence is related to material cracks, excessive deformation, etc. The solution includes increasing pre-processing steps, raising pressure and temperature, introducing advanced ultrasonic detection technology, and strictly controlling process parameters to reduce the possibility of cracks.
Non-conforming dimensions
Non-conforming dimensions of ring forgings are another common problem. The main reason is the shape change after forging and the shrinkage during heat treatment. The solution includes optimizing design and selecting appropriate materials, strengthening the slope protection design, and implementing strict dimension inspection.
Surface and internal defects
Surface and internal defects are one of the most serious problems in the production process of ring forgings. The main reason is the impurities in the material and the unevenness generated during the processing. The measures to ensure the surface and internal structure quality include increasing mechanical processing or other cleaning technologies, raising pressure and temperature, and reducing process lubricants.
Bending and deformation
Bending and deformation often occur in the manufacturing process of ring forgings, mainly due to incorrect temperature, material, and design parameters. The solution includes adjusting process parameters, strengthening ring forging fixation and management to keep it stable during shaping.
Improper heat treatment
Heat treatment has a crucial impact on the performance of ring forgings. If the time, temperature, or cooling speed of heat treatment goes beyond the scope, it will result in uneven hardness and strength of the product. The solution includes optimizing the heat treatment plan, strictly controlling the heat treatment time and temperature, and controlling the situation during the manufacturing process when problems occur.
In conclusion, the above lists five main common problems that encounter in the manufacturing process of ring forgings along with their corresponding solutions. The quality of ring forgings depends on strict control and inspection of all production stages. By constantly improving the quality of the manufacturing process, technological level, innovation, using appropriate materials, and implementing scientific heat treatment methods can significantly enhance the quality and performance of ring forging products.
