“…The third one is inaccuracy of temperature characteristics of material properties and heat transfer coefficients [8]. An incorrect value of such properties like electric conductivity, density, thermal conductivity and specific heat could cause differences of calculated final temperature of about 100 K [9]. And finally a way of cooling and the cooling rate.…”

The overview of the induction surface hardening methods were presented in the paper. Two examples are considered: continual hardening of cylinders made of steel 38Mn6 and dual frequency hardening of gear wheels made of steel 40 HNMA. Results of measurements provided at the experimental stand were presented. Acceptable accordance between measurements and numerical computations were obtained. Final conclusions were formulated. (Hartowanie indukcyjne powierzchniowe-porównanie różnych metod) Streszczenie. W pracy dokonano przeglądu metod hartowania indukcyjnego powierzchniowego elementów stalowych. Rozpatrzono dwa przypadki: hartowania przelotowego wałków ze stali 38Mn6 oraz hartowania dwuczęstotliwościowego kół zębatych ze stali 40HNMA. Przedstawiono wyniki pomiarów na stanowisku doświadczalnym. Uzyskano zadowalającą zbieżność między wynikami pomiarów i obliczeń numerycznych. Przegląd metod hartowania indukcyjnego powierzchniowego elementów stalowych

“…Computations have been realized by means of the 3D Flux software for calculation of the coupled electromagnetic and temperature field during induction heating and cooling as well as QT steel software, supported by several personally developed procedures for calculation of hardness and microstructure fields [16]. The influence of dependences of material properties on temperature and magnetic field intensity was described, for instance, in [10,17,18]. The time dependence of temperature for the whole tooth during the process (induction heating, very short austenitization (hundreds milliseconds or less) and cooling) has been calculated and recorded.…”

Induction surface hardening means the hardening of a thin zone of the material only, while its core remains soft. The paper deals with the modelling of the Consecutive Dual Frequency Induction Hardening (CDFIH) of gear wheels and its validation. For gear wheels with modulus m smaller than 6 mm a contour profile of hardness distribution could be obtained. The investigated gear wheel is heated first by a medium frequency inductor to the temperature approximately equal to the modified lower temperature Ac 1m . It means beginning of the austenite transformation. Then the gear wheel is heated by the high frequency inductor to the hardening temperature making it possible to complete the austenite transformation and immediately cooled. In order to design the process it is necessary to identify modified critical temperatures and to obtain expected temperature distribution within the whole tooth.
