Shanxi Jianing Forging has collected real-world engineering cases of long shafts, short shafts, drive shafts, and marine nuclear power shaft forgings, fully showcasing the forging process of shaft forgings, finished product precision, and practical application scenarios for heavy equipment.
During the production line upgrade, a building materials machinery factory in Weinan needed a batch of reliable energy shaft forgings for key transmission components. The factory sets high requirements for the strength, wear resistance, and dimensional accuracy of forgings to help ensure continuous equipment operation. Jianing Forging (hereinafter referred to as "our company") undertook the custom task for this batch of shaft forgings, providing customers with supporting solutions through technical integration and process optimization.
The original shaft forgings exhibit increased surface wear and fatigue fracture after a period of use, leading to increased equipment downtime and higher maintenance costs. At the same time, the quality of forgings varies greatly between batches, making it difficult to meet the stability requirements of continuous production. Customers urgently need a shaft forging that balances strength and toughness, offers good quality consistency, and offers a longer service life.
To address customer pain points, our company focuses on three stages: material selection, forging process, and heat treatment control: selecting high-quality alloy steel billets and strictly controlling chemical composition; Uses multi-directional forging technology to refine grain structure and eliminate internal defects; Subsequently, combined with quenching and tempering treatment, it achieves comprehensive mechanical properties with good toughness and good compatibility. Finished shaft forgings undergo non-destructive testing and full dimensional inspection, helping to eliminate defects such as cracks and shrinkage cavities. After actual installation, the equipment runs smoothly, wear rates have decreased, and replacement cycles have been extended to more than twice that of the original product, helping customers effectively lower overall operating costs.
