Embodiment Construction
[0012] The wheel components used in the following preferred modes and comparative samples are: C: 0.62, Si: 0.29, Mn: 0.74, P: 0.018, S: 0.003, and the rest: trace amount.
[0013] Preferred way 1: Place the train wheels in a high-temperature state maintained in the austenite region in a horizontal quenching table. During the rotation of the wheel, the tread is cooled by spraying water for 20-25 seconds. The temperature measured by the thermocouple embedded 5mm below the tread is cooled to a certain temperature range below the austenite transformation temperature of the steel. The exact Said to be 595-610 ℃, stop spraying water, at this time the surface temperature of the tread is between 550-565 ℃, and a layer of 5-8mm thick pearlite structure is formed on the surface of the wheel tread. After the water spraying is stopped, the wheel is left to stand for 60-70 seconds to use the heat conduction in the high-temperature zone inside the rim to make the surface temperature rise a...
