Shanxi Jianing Forging has gathered real-world cases of wind power flange rings, ring gears, bearing rings, roller rings, and other ring landings, with a complete range of finished forging products for carbon steel, stainless steel, and alloy rings, providing reference for product selection and non-standard solutions.
A heavy factory at a mine in Ordos, Inner Mongolia, has high performance requirements for key ring forgings during production. The plant's equipment has long been exposed to heavy loads, frequent impact, and wear environments, causing frequent fatigue cracks and deformation issues in the original forgings, directly affecting production rhythm and overall equipment service life. Jianing Forging was invited to provide customized ring forging solutions to help extend the normal operating cycle of the equipment.
The main pain points faced by this heavy factory are as follows: First, the original ring forgings exhibited obvious plastic deformation and localized cracking under long-term high-load conditions, with frequent replacement and continuously rising maintenance costs. Second, existing suppliers fluctuate greatly in dimensional accuracy and material uniformity, requiring repeated adjustments during assembly and reducing production line efficiency. In addition, extreme working conditions impose stricter requirements on the impact toughness and fatigue resistance of forgings, making it difficult for conventional forging processes to meet the demands of continuous production.
To address these pain points, Jianing Forging optimizes the ring forgings on multiple dimensions. In terms of material selection, a customized alloy formula is adopted, and multiple heat treatment steps are used to make the internal structure of the forgings dense and grains fine, thereby enhancing fatigue resistance and impact resistance. At the process level, fine ring rolling and preforming technologies are introduced to control dimensional tolerances within stricter ranges, reducing machining allowances and promoting assembly consistency. At the same time, ultrasonic testing and mechanical performance sampling are conducted on each batch of products to avoid internal defects at the source. The delivered ring forgings in actual applications have an average service life about 50% longer than the original components, significantly reducing equipment downtime due to malfunctions, effectively lowering the customer's overall operating costs.
