A Study on the Induction Heating Analysis of Round bar for TR forging
TR단조를 위한 환봉의 유도가열 해석에 관한 연구

Abstract
The TR forging is a kind of continuous grain flow forging. The preform of crank shaft for TR forging process was a round bar with a ring groove. In the first stage, the preform was partly heated by induction heating and then forged by vertical and horizontal force in sequence. In this study, the simulation process of induction heating was proposed to evaluate the temperature distribution of preform for TR forging. The equivalent circuit method was adopted to find coil current of the preform with a various dimensions and power levels. With these results, the coupled electromagnetic and transient thermal analysis for induction heating was performed to evaluate the temperature distribution at the preform of crank shaft during induction heating process. This FE analysis technique with equivalent circuit method was verified by comparing the analysis results with the experimental results.
