Numerical Model of Induction Heating under Quenching Taking into Account the Austenization Process in Carbon Steels

In the present work the task was to develop an algorithm and, on its basis, to create a numerical model, which for cylindrical-shaped parts at a given frequency, part diameter and quenching depth finds the required power and heating time, taking into account the achievement of the required homogenization temperatures on the surface and the austenization temperature at the hardening depth. The required temperatures must be coordinated with the heating rate, which varies significantly on the surface of the part and the depth of hardening. The paper presents numerical modeling results for steel 45 cylindrical-shaped bodies taking into account different criteria for setting the hardening depth. A hardening modes comparison taking into account different hardening layer architecture is also presented.
