description: The topic of the final qualification work: "Development and research of a thyristor parallel current inverter for induction hardening of steel drill pipes with a diameter of 60 mmâ This bachelor's work begins with the fact that it is told what induction heating is. It describes where induction heating can be used, its advantages, disadvantages, and also takes into account the comments. After that, there is an analytical calculation of the heating of the drill rod for induction surface quenching. Where the initial data are initially presented and Figure (2.1) is shown, the inductor â part system for induction surface hardening of the rod. Then the frequency is selected. After that, there is a thermal calculation of the drilling rod heating for quenching, which is completely performed in the Mathcad program. All the necessary parameters were obtained and entered in Appendix 1. After all of the above, in the COMSOL Multiphysics program, a part-inductor model was built with a demonstration of the full geometry. The drawings also demonstrated how the part is immersed at different points in time and how the temperature changes over time.
