The Shanxi Jianing Forging Forging Train Wheel, Mine Overhead Wheel, and Heavy-Duty Overhead Wheel Forging Project features mature forging technology for high-strength wheels, excellent load-bearing performance, and suitable for heavy-duty conditions in rail transit and mines.
A forklift factory in Pu'er, Yunnan, has long been engaged in material transfer operations in mining areas. Its forklift wheels endure harsh conditions such as high loads, heavy gravel, and frequent start-and-stop conditions. The company's original wheel forgings were processed from ordinary steel, but after continuous use of relatively high strength, issues such as insufficient wear resistance and susceptibility to fatigue cracks became exposed, seriously affecting operational efficiency and equipment safety. To improve the overall wheel performance, the factory sought professional forging suppliers for technical upgrades.
The core pain points faced by the factory include: short wheel service life, requiring replacement every 300 hours on average; The presence of tiny pores and uneven microstructure inside the forging leads to early cracking at the rim; The raw material strength cannot match the impact load of gravel pavements in mining areas, causing frequent deformation; At the same time, due to unstable delivery cycles from original suppliers, spare parts inventory pressure is high, affecting production schedules.
To address these pain points, Jianing Forging provides customized wheel forging solutions. By selecting high-quality alloy structural steel, optimizing forging ratios and heat treatment processes, forgings are refined and density is increased. The new solution not only improves dimensional accuracy but also raises tensile strength to over 850 MPa and yield strength to 700 MPa, enhancing fatigue resistance. Additionally, it uses fine die forging technology, resulting in smoother transitions at the rim rounded corners, effectively dispersing and concentrating stress. After on-site installation and verification, the average service life of new forgings has increased to over 1200 hours, with a failure rate reduced by about 60%, and delivery cycles compressed to under 15 days, helping customers lower overall operating costs.
