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 metallurgical vehicle parts factory has long produced wheel forgings for high-temperature and heavy-duty environments in steel mills. During commissioning, the factory found that existing products exhibited deformation and early fatigue cracks under continuous high-load operation, seriously affecting equipment operation stability and maintenance costs. Jianing Forging provided customized wheel forging solutions, improving the overall performance of wheel forgings by adjusting forging processes and material ratios.
Metallurgical vehicles frequently start and stop in high-temperature workshops and operate under heavy loads, which places high demands on the strength, heat resistance, and fatigue resistance of wheel forgings. The forgings supplied by the original supplier showed localized plastic deformation after 8 months of continuous operation, resulting in wheel roundness loss and increased track wear and replacement frequency. At the same time, the lifespan of welded and repaired forgings is greatly shortened, and overall operating costs remain high. Customers urgently need wheel forgings that can maintain dimensional stability and long-term reliability under high temperature and heavy load conditions.
Jianing Forging addresses customer pain points by optimizing materials and using microalloying formulas to enhance high-temperature strength; At the same time, the forging flow distribution is optimized, allowing metal fibers to be arranged continuously along the radial direction of the wheels, enhancing fatigue resistance. By controlling forging temperature and cooling rate, grains are refined to avoid concentrated thermal stress. Finished wheel forgings have been verified on actual loading and have been continuously operated for 18 months under the same conditions without deformation, with service life more than doubling compared to before. In addition, Jianing Forging provides complete dimensional inspection reports and flaw detection records, helping each product meet the installation requirements of metallurgical vehicle parts factories.
