The company has developed a heat treatment method for medium-carbon low-alloy steel road wheels, which includes quenching and heating the rolled and slow-cooled railway wheels at 840-860°C, water spray cooling, tempering at 500±10°C, and working at 890-910°C. The purpose of the frequency induction heating and compressed air cooling process is to make the wheel, on the basis of maintaining the original mechanical properties, significantly reduce the depth of the abnormal tissue area near the surface of the tread, or completely eliminate the abnormal tissue layer, so as to improve the performance of the wheel and reduce the cutting processing cost.
