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 construction machinery factory in Harbin, Heilongjiang (hereinafter referred to as the "Client") is a company that has long been engaged in the production of construction machinery components. To improve the load-bearing performance of key equipment components, the plant needs to purchase a batch of high-standard ring forgings for assembling large slewing support structures. After extensive comparison, the client ultimately chose Jianing Forging as its ring forging supplier, and the two parties completed this customized production task through cooperation.
Customers face the following issues during their original production processes:
1. Insufficient dimensional accuracy of annular forgings leads to frequent clearance deviations during assembly, affecting equipment operational stability.
2. Internal micropores and loose defects in the internal structure are prone to fatigue cracks under heavy load conditions, shortening the service life of components.
3. Conventional forging processes cannot meet the higher requirements for material density and flow distribution, limiting the overall improvement of equipment performance.
4. Multiple suppliers' delivery cycles are unstable, making it difficult to match customers' tight production schedules.
To address these pain points, Jianing Forging offers the following solutions:
1. Uses fine ring rolling technology, strictly controlling rolling parameters and die precision, helping to stabilize the inner and outer diameter and height tolerances of ring forgings within ±0.5mm, meeting customer assembly requirements.
2. Optimized forging ratio and heating regime, combined with multi-pass deformation processes, effectively eliminates internal micro-pores, achieving dense and uniform material microstructure, thereby improving fatigue life.
3. Using computer numerical simulation (CAE) to assist in designing the metal flow direction, the fiber flow is distributed along an annular profile, enhancing bearing capacity and reducing stress concentration.
4. Establish a flexible production scheduling mechanism to shorten the regular delivery cycle to 20 days and provide expedited services to support smooth progress of customers' production plans.
In this collaboration, the ring forgings delivered by Jianing Forging were tested by a third party, and all performance indicators met the customer's technical agreement requirements. The customer reported an approximately 15% improvement in equipment assembly efficiency, and after six consecutive months of operation, no early failures occurred.
