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.
The service target for this service was a petrochemical equipment factory in Qiqihar, Heilongjiang. The company needs to use high-performance shaft forgings in its refining unit to rotate the core transmission components of the equipment. With mature forging technology and extensive industry experience, Jianing Forging provided the company with a complete set of custom shaft forging solutions, helping to improve the stability of equipment operation.
This petrochemical equipment factory faces multiple challenges in shaft forgings procurement: on one hand, the equipment is long-term in high temperature, high pressure, and heavy-duty conditions, requiring high strength, fatigue resistance, and dimensional accuracy for shaft forgings; On the other hand, products delivered by original suppliers suffered from large performance fluctuations between batches and insufficient internal microstructure, leading to frequent equipment vibrations and sealing failures, affecting production continuity. In addition, shaft forgings have complex shapes and difficulty in controlling machining allowances, making it difficult for traditional processes to balance efficiency and quality.
To address these pain points, Jianing Forging provides systematic solutions from three dimensions: materials, processes, and inspection. On the material side, selecting high-quality alloy steel and optimizing composition control helps improve material purity and uniformity; In the forging stage, a multi-directional forging + temperature-controlled speed process is used to effectively eliminate internal looseness, refine grains, and increase forging density; Subsequent heat treatment is performed through precise quenching and tempering parameters to achieve uniform hardness and excellent overall mechanical properties of the shaft forgings. Combined with precision machining and non-destructive testing, the final delivered shaft forgings have dimensional tolerances within ±0.05mm, and the surface quality meets high-precision assembly requirements. This solution not only solved the customer's original fault issues but also increased the service life of shaft forgings by more than 30%, earning high recognition from the customer.
