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.
A construction machinery factory in Xuchang, Henan, faced the dual challenges of improving product performance and controlling costs during the production of key shaft forgings. The factory's original shaft forgings had internal uneven microstructures and fluctuations in service life, affecting the assembly quality of the entire machine and customer satisfaction. To address this challenge, the factory collaborated with professional forging suppliers, optimizing forging processes and material selection, and successfully developed shaft forging products that meet high-load operating conditions.
Customers mainly encounter the following issues when using shaft forgings: First, microcracks and looseness inside the forging, leading to insufficient fatigue life; Second, poor quality stability between batches, with some shaft forgings exceeding deformation standards after heat treatment; Third, the material utilization rate under traditional processes is relatively low, increasing manufacturing costs. These issues directly affect the reliability of equipment operation and maintenance cycles.
To address these pain points, the partners provided a systematic solution: using fine forging technology to control the deformation process and eliminate internal defects; By optimizing heating and cooling parameters, it helps refine grains and uniform microstructure; Simulation methods are introduced to predict deformation trends in advance and adjust mold designs. The final delivered shaft forgings meet design standards in key indicators such as hardness, tensile strength, and impact toughness, with improved batch pass rates and reduced subsequent machining allowances, lowering overall costs.
