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 heavy mining truck factory located in Huairou, Beijing, has long been engaged in the production and maintenance of wheel components for mining dump trucks. The wheel forgings produced by this factory must withstand relatively high strength impacts and complex working conditions, requiring extremely high material performance and machining precision. Due to the limitations of traditional processes, wheel forgings frequently experience cracking, deformation, and other issues during use, severely limiting equipment operational efficiency and safety.
The factory's original wheel forgings had the following shortcomings: First, the material lacks toughness, making fatigue cracks prone to formation under heavy loads and harsh road conditions; 2. Low internal tissue density, leading to a decrease in overall strength; 3. Unstable control of machining allowance, resulting in time-consuming and low pass rates for subsequent finishing; 4. Short product lifespan and high replacement frequency, increasing maintenance costs and downtime. These pain points directly affect the attendance rate and operational efficiency of mining trucks.
To address these pain points, Caring Forging has customized high-performance wheel forgings solutions for this mining truck heavy factory. By optimizing the forging temperature curve and deformation process, the grain structure of the material is improved, enhancing the fatigue resistance and overall strength of the forging. At the same time, precision die forging technology is used to keep machining allowances within an extremely small range, reducing subsequent machining volume and improving material utilization. After multiple process validations and on-site tests, the service life of this wheel forging under the same operating conditions has been extended by more than 30% compared to the original product, effectively reducing the risk of breakage and helping customers achieve more stable production cycles and lower overall costs.
