摘要
The paper presents the experimental and numerical results obtained by the induction heating a steel disk. This study has been aimed at realizing the local uniform heating the disk at minimum temperature departure from 4513 degrees C. The system-of-interest included 3-turn inducers and a steel disk heated up. The computer-based investigation results were implemented at a laboratory mock-up. The temperature distribution over the disk material and its changes were recorded by a thermal imager. Simulation of electromagnetic and thermal processes occurring in heating a rotating disk-shaped work piece was carried out using ANSYS APDL base. A comparison between the obtained numerical data and experimental one showed a disagreement of about 5 %. It pointed to an adequacy of simulation carried out. A detailed analysis of the disagreement sources was made.
