The number of teeth of the gear shaft is 85 and the weight is 1.5kg, The structure of gear shaft after normalizing is: F+S for hypoeutectoid steel, S for eutectoid steel, S+ secondary cementite for eutectoid steel, and it is discontinuous.
1. Normalize the heating temperature
Usually, the heating temperature of hypoeutectoid steel is usually 30 ~ 50℃ above Ac3, and the normalizing temperature of medium carbon alloy steel is usually 50 ~ 100℃ above Ac3. After a certain period of heat preservation, the cooling method is called high temperature normalizing. FIG. 6 shows the heating temperature of 42CrMo
2. Normalize heating and holding time
Heat preservation time, this problem is more complex, generally determined by the test, but there is an empirical formula: T = αKD T - heat preservation time (min) α - heating coefficient (min/mm) K - workpiece heating correction coefficient D - effective thickness of the workpiece (mm).
