rail wheel axle from china good quality railway wheel set steel rail wheels 42crmo steel from rail wheels factories

Detailed specification of rail wheel axle from china good quality railway wheel set steel rail wheels 42crmo steel from rail wheels factories

Forging a wheel blank from a steel block,forging operation forms the rough contour of the wheel,wheel rolling,this complicated geometric shape including configure different parts made by simultaneous various rolls.heat treated,1650°F temperature hardening the furnace of entire wheel heating and spinning wheel with a water-spray quench.Final and most important step:ultrasonically inspection to evalutae the internal quality of wheels.

A good wheel must have the feature of perfect combination of hardness for wear resistance , the strenght and toughness!

In the heavy haul industry,we have many comprehensive product lines . Whatever your requirements, our Kingrail can deliver the highest quality, most reliable rail wheels for the long haul accordingly.

Wheels tough enough ,72% longer wheel life . lower freight car operating expenses, less time for wheel maintenance to 72% reduction in wheel-set removals translates into. enhanced “fluidity of the service.” Made from a patented material that provides increased resistance to thermal degradation, our various wheel can take the heat at higher temperatures. Available wheel in various diameters for rail -road vehicle and even locomotives.

STANDARD OF CHEMICAL COMPOSITION FOR STAINLESS STEEL MATERIAL(%)

we produce wheels with such close tolerances that they are better balanced than other wheels, contributing to maximum traction and longer wheel life.

when your railcars rolling in some of the tough railroad environments, the wheels made by our experience, dedication and efficiency in heavy haul operations is unequaled,which to be machined and restored to its original shape multiple times during its lifetime.

Main Testing and Inspection Device

We all know that wheel exchanging frictional forces with the rail will cause the regular wear of railroad wheels.So when these occur on the wheel: traction, braking and especially curve negotiation. wear is produced by longitudinal tractive/braking efforts and tends to concentrate on the central portion of the wheel tread when in traction and braking, the process of wear formation during curve negotiation is more complicated involves both longitudinal frictional forces. There are the rolling radius difference between the inner and outer wheels and transversal frictional forces caused by the wheelset travelling along the curve with a non-zero angle of attack.

We are located in the city Maanshan which is a steel city with our high-quality steels, so that is the base suitation for us to produce top-class forged wheels with the standrads that meet the needs of a high-speed rail network.
