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 metallurgical equipment factory has long faced issues such as difficulty in controlling dimensional tolerances, insufficient material uniformity, and unstable delivery cycles in the procurement process of ring forgings. In traditional processes, large-sized ring parts often exhibit excessive ovality and uneven grain size, leading to increased machining allowances and higher defect rates, seriously affecting assembly efficiency and equipment reliability.
The ring-shaped forgings originally supplied by the plant tend to develop local hardness differences after heat treatment, and the finished product surface has a risk of fine cracks, requiring additional flaw detection and repair procedures. At the same time, the weight consistency of multiple batches of ring parts is poor, adding extra burden to dynamic balance correction. Insufficient supply chain response speed, frequent delays in urgent orders, and constraints on equipment delivery cycles.
To address these issues, Jianing Forging relies on multi-station precision forging lines and implements a full-process temperature-controlled rolling process, ensuring that the dimensional accuracy of the inner and outer diameters of ring parts is stably controlled within IT9 level. By optimizing upsetting and punching parameters and eliminating central loose defects, the ultrasonic flaw detection pass rate exceeds 99%. The material uses a customized alloy formula, and after quenching and tempering, the hardness fluctuation range narrows to ±2HRC, reducing the difficulty of subsequent processing. In addition, the company has established a rapid production scheduling mechanism, enabling delivery of standard specifications within 7~15 days, effectively supporting customers' production schedules.
