For some mining or subway, need to use special safety wheels, we have various Special wheels for mining or safety wheels.
For such wheels, always difficulty on machining since easier to transformation.
Our wheels are rolled or forged, from ingot till package and delivery, all make in one wareshop, which save much cost and easier to control quality.
Special wheels for mining or safety wheels are produced as per customer drawings and specifications, 100% inspection before shipment, inspection items such as UT, MT, size test, mechnical capacity, element composition test, issue quality documents for each batch, marking on each wheels to better tracking.
The wheels are banned as per wear to scrap line or broken, but always re machining for first several wearings.
Most train wheels have a conical geometry, which is the primary means of keeping the train's motion aligned with the track. Train wheels have a flange on one side to keep the wheels, and hence the train, running on the rails when the limits of the geometry-based alignment are reached, e.g. due to some emergency or defect, which always need safety wheels for protection. Some wheels have a cylindrical geometry, where flanges are essential to keep the train on the rail track.
