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 factory in Panjin, Liaoning, has long used wheel forgings that frequently experience rapid wear, localized cracks, and insufficient load-bearing capacity during operation, seriously affecting the vehicle's normal operating cycle and maintenance costs. The plant was eager to find a wheel forging solution that could improve wear resistance, extend service life, and contribute to safety.
The metallurgical vehicle plant faces the following core challenges in actual operation: First, wheel forgings experience abnormal wear rates under high-frequency and high-load operation, with high replacement frequencies and high replacement frequencies, increasing losses from production stoppages; Second, poor internal stress control in the forgings leads to crack propagation and poses safety hazards; Third, the original process has shortcomings in terms of material purity and structural uniformity, making it difficult to meet the stable requirements of heavy-load, high-temperature differential conditions.
To address these pain points, we offer customized wheel forging solutions. By optimizing forging process parameters and selecting high-quality alloy steel materials, the density and mechanical properties of the forgings are enhanced. Specific measures include: using multi-directional forging technology to improve metal flow distribution and enhance fatigue resistance; Implement fine heat treatment processes to refine grains and eliminate residual stress; Combined with strict ultrasonic flaw detection and dimensional inspection processes, each product meets the wear-resistant, crack-resistant, and load-bearing requirements of metallurgical vehicle conditions. Actual installation validation shows that the average service life of wheel forgings has increased by about 40% compared to the original plan, with a reduced crack occurrence rate, helping the customer optimize equipment operation cycles and maintenance costs.
