MATHEMATICAL MODELING OF SURFACE INDUCTION HEATING

The paper presents possibilities of controlling temperature field distribution in induction heated charge. The change of the distribution was obtained with use of sequential two-frequency heating. The study was conducted as multi-variant computer simulations of strongly coupled to each other field: the electromagnetic and the temperature fields. For the analysis, the professional calculation package using the finite element method Flux 3D was used. The problem of obtaining an appropriate temperature distribution in a heated charge of, a complex shape is very important in many practical applications. A typical example is a quenching of gears. For such applications, it is required to obtain a surface and in desired depth, uniform temperature distribution on the tooth face and top land and on the bottom land of the gear. The obtained temperature should have proper distribution and value. Achieving such a defined distribution is very difficult. During the study over a dozen different calculation variants were examined.
