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 parts factory in Handan, Hebei has long been engaged in the production of mining truck parts. Its wheel forgings frequently suffer from uneven wear and short service life under complex mining conditions, seriously affecting vehicle operating efficiency and maintenance costs. To solve this problem, the factory sought cooperation with enterprises with extensive forging experience to enhance the overall performance of wheel forgings.
Mining trucks operate in harsh environments with heavy loads, high impact, and dusty environments. The original wheel forgings have the following prominent issues: First, insufficient material strength, which easily causes surface fatigue cracks during frequent braking and bumpy road sections; Second, unstable heat treatment processes lead to uneven hardness distribution and premature local wear; Third, poor product dimensional consistency, requiring repeated adjustments during installation, which reduces assembly efficiency. These pain points directly increase equipment downtime and maintenance costs, urgently requiring systematic optimization from materials and processes to finished products.
To address these pain points, Jianing Forging offers customized wheel forging solutions. First, high-quality alloy steel raw materials are used, and the grain structure is refined through multiple forging processes, increasing the internal density of the forging and enhancing fatigue resistance. Second, the heat treatment curve is optimized to achieve hardness uniformity within the HRC±2 range, balancing wear resistance and toughness. Additionally, the introduction of fine molds and CNC machining helps key dimensions such as outer diameter, inner holes, and end face runout meet drawing requirements, resulting in high consistency in mass production and direct installation without additional modifications. After actual installation and verification by customers, this solution extends the average service life of wheel forgings by about 40%, significantly reduces equipment failure rates, and has received high recognition from mining truck parts manufacturers.
