Influence of the geometry and current of the inductor on the process of chemical heat treatment of titanium in a container with a carbon-containing medium

This study presents the results of modeling the process of chemical heat treatment (CHT) of titanium disk-shaped samples located in a container with a carbon-containing medium. The main parameters of the considered process were the inductor current and the geometry of the "inductor – container – sample" system, namely, the number of turns, the height and internal diameter of the inductor at constant values of the height and external diameter of the container for CHT. The operating temperature of the outer surface of the container varied in the range from 1100 °C to 1350 °C, which was achieved at an inductor current from 3.4 kA to 5.0 kA in a narrow frequency range of 88±2 kHz. The obtained plots of the distribution of temperature fields made it possible to assess the heating efficiency of inductors of various designs.
