DYNAMIC TEMPERATURE FIELD IN THE FERROMAGNETIC PLATE INDUCED BY MOVING HIGH FREQUENCY INDUCTOR
2014
The subject of the paper is the temperature distribution in the thin metallic
ferromagnetic plate influenced by moving linear high frequency induction
heater. As a result of high frequency electromagnetic field, conducting
currents appear in the part of the plate. Distribution of the eddy-current
power across the plate thickness is obtained by use of complex analysis. The
influences of the heater frequency, magnetic field intensity and plate
thickness on the heat power density were discussed. By treating this power as
a moving heat source, differential equations governing distribution of the
temperature field are formulated. Temperature across the plate thickness is
assumed to be in linear form. Differential equations are analytically solved
by using integral-transform technique, Fourier finite-sine and finite-cosine
transform and Laplace transform. The influence of the heater velocity to the
plate temperature is presented on numerical examples based on theoretically
obtained results. [Projekat Ministarstva nauke Republike Srbije, br. TR 35040
