Technical Field

Background
The quenching of steel is a heat treatment process of heating the steel to a temperature above a critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), preserving the heat for a period of time to make the steel fully or partially austenitized, and then rapidly cooling the steel to a temperature below Ms (or isothermal near Ms) at a cooling speed greater than a critical cooling speed to perform martensite (or bainite) transformation. The solution treatment or heat treatment process with a rapid cooling process of materials such as aluminum alloys, copper alloys, titanium alloys, tempered glass, etc. is also generally called quenching.
The heat treatment is a method for improving the comprehensive mechanical property of the material, if the conventional production and the reheating treatment of the wheel are carried out, the problems of insufficient processing capability of equipment, poor welding performance, concentrated cold processing stress and the like can be solved, but the deformation control difficulty of the heat treatment of the whole wheel is high, the cost of the material suitable for the heat treatment is high, and the heat treatment process specially designed for the wheel production is blank, so the method is not adopted by wheel manufacturers.
It is well known that the dimensional and shape changes of steel during quenching are one of the most difficult problems faced by heat treatment. Compared with the common wheel, the lightweight wheel has thinner wall thickness and relatively weaker deformation resistance. The phase change stress is the main reason of heat treatment deformation, and the thermal stress generated by the difference of the inner layer cooling speed and the outer layer cooling speed during quenching is reasonably utilized, so that the deformation caused by the phase change stress can be counteracted to the maximum extent, and a group of quenching devices with the technological parameters of quenching temperature, cooling speed, cooling amplitude and the like needs to be found. In addition, solving the problem of uneven heating and cooling, selecting an appropriate cooling medium, and improving the conventional wheel production equipment are new problems of the wheel heat treatment production equipment.
