The company has developed a device to eliminate the gas-cut hardened layer of railway wheel samples, and heat and anneal the cut and hardened surfaces of the wheel samples, including the sample fixture and heating structure for holding the wheel samples. The wheel samples are: The test block obtained by gas cutting of wheel spokes, the device is provided with a water tank, the sample holder is placed in the water tank, and the gas-cut hardened layer of the wheel sample is higher than the water surface level in the water tank. The present invention also provides a process method adopted by the above device. By adopting the above technical solution, the hardness of the gas-cut hardened layer can be reliably reduced, thereby significantly improving the work efficiency of the subsequent sawing process of the gas-cut hardened layer, reducing the consumption of saw blades, and being easy to operate; it can also ensure the mechanical properties of the wheel spokes. Not affected by this processing, thus ensuring the authenticity of the test results.
