Forging a wheel blank from a steel block,forging operation formsthe rough contour of the wheel,wheel rolling,this complicatedgeometric shape including configure different parts made bysimultaneous various rolls.heat treated,1650°F temperaturehardening the furnace of entire wheel heating and spinning wheelwith a water-spray quench.Final and most importantstep:ultrasonically inspection to evalutae the internal quality ofwheels.
A good wheel must have the feature of perfect combination ofhardness 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 highestquality, most reliable rail wheels for the long haul accordingly.
Wheels tough enough ,72% longer wheel life . lower freight caroperating expenses, less time for wheel maintenance to 72%reduction in wheel-set removals translates into. enhanced “fluidityof the service.” Made from a patented material that providesincreased resistance to thermal degradation, our various wheel cantake the heat at higher temperatures. Available wheel in variousdiameters for rail -road vehicle and even locomotives.

We all know that wheel exchanging frictional forces with the railwill cause the regular wear of railroad wheels.So when these occuron the wheel: traction, braking and especially curve negotiation.wear is produced by longitudinal tractive/braking efforts and tendsto concentrate on the central portion of the wheel tread when intraction and braking, the process of wear formation during curvenegotiation is more complicated involves both longitudinalfrictional forces. There are the rolling radius difference betweenthe inner and outer wheels and transversal frictional forces causedby the wheelset travelling along the curve with a non-zero angle ofattack.
We are located in the city Maanshan which is a steel city with ourhigh-quality steels, so that is the base suitation for us toproduce top-class forged wheels with the standrads that meet theneeds of a high-speed rail network.
