[0035] The internal liquid supply mechanism comprises an internal liquid supply pipe 31 and a pressure pipe 32, the pressure pipe 32 is communicated with the membrane breaking cavity 11, and the amount of liquid entering the membrane breaking cavity 11 per unit time is greater than or equal to the amount of liquid discharged from the membrane breaking groove 14 per unit time. The flow channel I 41, the flow channel II 42 and the flow channel III 43 are all communicated with the internal liquid supply pipe 31.
[0036] The rotating impeller 51 is a water pump impeller in this embodiment, and can also be other impellers in other embodiments, which can be driven by water flow.

During immersion quenching, because the atomization process of the quenching liquid is in the quenching liquid, the cooling rate of the surface layer metal of the inner and outer surfaces of the pin sleeve decreases, and the large-flow quenching water can ensure that the surface layer metal is always at a relatively low temperature of 120-140℃, so as to ensure the temperature drop rate of the inner layer metal of the tread. The temperature drop rate difference between the surface layer metal and the inner layer metal is reduced. At the same time, the temperature drop rate of the surface layer metal is reduced, which can improve the abnormal organization thickness layer of the surface layer metal of the wheel tread.
