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.
In the ring forging project of a certain metallurgical heavy plant, the client set strict requirements for the overall performance and manufacturing precision of large ring parts. The company has long been engaged in metallurgical equipment manufacturing, and the quality of its core component—the ring forging—directly affects the operational stability and lifespan of the equipment. After taking on this task, Jianing Forging implemented full-process control from material analysis to finished product delivery, with the final products meeting all customer technical specifications.
Customers mainly face three challenges in ring forging processing: first, large forgings and uneven wall thicknesses, making it difficult for traditional processes to achieve concentricity and roundness in both inner and outer diameters; Second, the material is relatively high-strength alloy steel, with a narrow hot working window, making cracks or uneven microstructure prone to occurring; Third, tight schedules, requiring completion of all processes from blank to finishing within the specified timeframe, while also controlling costs. Several suppliers who tried before failed to meet demand due to low qualification rates or delivery delays.
To address these pain points, Jianing Forging has adopted the following solutions: using multi-directional upsetting and punching processes, combined with specialized tooling, to effectively control the deformation of ring-shaped parts, which helps with concentricity and roundness; By optimizing the heating curve and forging ratio, the internal structure of alloy steel is uniformly refined and the risk of surface cracks is eliminated; At the same time, using programmable temperature control systems during heat treatment helps maintain consistent performance. Additionally, the project team intervened in design review in advance, keeping machining allowances within reasonable limits, which not only shortened subsequent machining time but also reduced material waste. The final delivered ring forgings have been tested by a third party, and all mechanical properties and dimensional tolerances meet customer standards.
