INFLUENCE OF THE TECHNOLOGICAL PARAMETERS ON THE DISTRIBUTION OF THE TEMPERATURE FIELD AND THE DEPTH OF THE HARDENED LAYER DURING THE INDUCTION HEATING OF THE INTERNAL CYLINDRICAL SURFACE OF SHIP STEEL BUSHINGS

The induction heating is widely used owing to the high quality performance, versatility and precise control means of the heating process. Hardening of internal cylindrical surfaces of ferromagnetic details and achieving preset depth of the hardened layer requires the provision of certain speed of heating and cooling, determinate surface temperature and distribution in depth. The purpose of this paper is to present a concrete solution for the shape of the inductor, heating the internal surface of a cylindrical detail, such as ship bushing, and simulation of the processes occurring in the system inductor-detail to study the influence of the process parameters on the depth of the hardened layer.
