Train wheel forgings are prone to fatigue cracks and rapid wear during long-term heavy loads and high-speed operation, directly affecting train safety and maintenance costs. Jianing Forging improves wheel fatigue life and wear resistance by optimizing alloy composition and fine forging processes, addressing safety and efficiency challenges from the source.
Train wheel forgings are prone to fatigue cracks and rapid wear during long-term heavy loads and high-speed operation, directly affecting train safety and maintenance costs. Jianing Forging improves wheel fatigue life and wear resistance by optimizing alloy composition and fine forging processes, addressing safety and efficiency challenges from the source.
The train wheel forgings produced by Jianing use relatively high-strength alloy steel billets and undergo multiple heating, pre-forging, final forging, and heat treatment processes, which help the structure be dense and the flow lines complete. The products are suitable for railway locomotives, freight cars, and urban rail transit vehicles, with relatively accurate dimensions and excellent dynamic balancing performance, meeting the requirements for continuous operation under harsh working conditions.
High fatigue strength: Uses microalloying design with finely refined grains, anti-fatigue cycle count superior to conventional processes.
Uniform hardness distribution: Through temperature and speed control, the hardness gradients of rims, spokes, and hubs are reasonably designed to prevent premature wear.
Dimensional stability: Fine molds and CNC machining post-processing, with dimensional tolerances controlled within ±0.5mm, high installation adaptability.
Peel resistance: Optimizes local heat treatment processes for tread, reduces the probability of hot cracks, and extends milling cycles.
Train wheel forgings are customized products, and the final price depends on material grade, specifications, quantity, and special technical requirements. Please provide detailed requirements or drawings, and we will provide you with a one-on-one and more accurate quotation.
