Low Curie temperature material for induction heating self-temperature controlling system

This paper presents low Curie temperature magnetic materials for induction heating. These materials are alloys based on SUS430. The magnetization decreases with increasing amount of additives. In order to increase the saturation magnetization, while keeping the Curie temperature constant, rare earth materials were added in this study. The compositions of alloys were investigated to realize a suitable Curie temperature. The temperature self-controlling function was also investigated in measurement of temperature distribution by using thermograph apparatus. Furthermore, thermoelectromagnetic field analysis was carried out as a numerical examination.
