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.
In the field of metallurgical heavy industry, shaft forgings, as key transmission components, directly affect the operational stability and service life of equipment. During a production line upgrade, a certain metallurgical heavy factory needed to purchase a batch of shaft forgings with high load capacity and long fatigue life to meet the demands of stringent continuous operation. Caring Forging, leveraging its deep understanding of heavy industry scenarios, undertook this specialized supply task.
The customer's original forgings developed fatigue cracks under long-term high-load conditions, and excessive replacement frequency led to production line downtime losses. At the same time, the dimensional consistency of shaft forgings after hot working is insufficient, requiring additional machining adjustments during assembly, which increases costs. Additionally, the client demanded strict supply cycles within 45 days, while traditional processes struggled to balance quality and timeliness.
Jianing Forging has solved the internal material microstructure and density issues by optimizing forging ratios and heat treatment curves, thereby improving fatigue resistance. Using precision control heating and multi-heat forging processes, dimensional tolerances are kept within ±1.5mm, reducing the allowance for subsequent processing. At the same time, relying on its own forging production line and rapid die-changing technology, we achieve delivery from raw materials to finished products within 28 days, meeting customers' tight deadlines.
The project selects high-quality alloy steel billets and undergoes forging, normalizing, tempering, and quenching and tempering treatments to achieve the uniformity of hardness of the forgings reaching HRC±2. The entire process is carried out according to the ISO 9001 quality management system. Every shaft forging undergoes ultrasonic flaw detection and magnetic particle inspection, ensuring no internal cracks, inclusions, or other defects. The final delivered products have an operational lifespan at the customer's site that is over 40% longer than the original solution, receiving written approval from the client's technical department.
