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 mining truck equipment factory in Huzhou, Zhejiang, has long used wheel forgings. Under complex conditions in the mining area, the original forgings frequently experience early fatigue cracking and insufficient wear resistance, resulting in high maintenance costs for equipment downtime. To solve this problem, the plant has entered into technical cooperation with Jianing Forging.
Mining trucks operate under heavy loads, bumps, and dusty environments, and wheel forgings must endure both significant impact loads and continuous wear. The customer's original forgings had shortcomings in hardness uniformity and internal density, with service life only half of expectations and frequent replacements, seriously affecting the mine's attendance efficiency and operational economy.
Jianing Forging has systematically optimized everything from material selection and forging processes to heat treatment according to the specific working conditions of its customers. By adopting a customized alloy steel formula combined with multi-directional die forging technology, the internal circulation distribution of the forging is more reasonable, improving fatigue resistance. At the same time, through precise temperature-controlled heat treatment, a good balance of hardness and toughness is achieved. After actual vehicle installation and verification, the service life of wheel forgings has increased by more than 60% compared to before, significantly reducing customers' overall maintenance costs.
