Abstract

This study was peformed to determine optimum induction heating conditions for a round bar of crankshaft. Four induction heating conditions were proposed and evaluated, employing numerical method, based on electromagnetic and sequential heat transfer analyses, resulting in optimum induction heating conditions which are finally proposed based on peak temperatures at heating zone and minimum temperature gradient through thickness of a round bar after 1 hour induction heating.

본 연구는 중형 크랭크샤프트 제작 과정에서 환봉을 가열하기 위한 최적의 유도가열조건을 결정하기 위한 것으로, 4가지 가열조건(가열코일 개수, 위치 등)에 대하여 수치해석적인 방법을 사용하여 전자기장 및 열전달해석을 순차적으로 수행하였다. 이러한 수치해석 결과로부터 일정시간 가열 후 크랭크샤프트 환봉 가열부에 발생하는 최고온도와 두께에 따른 내, 외부 최소 온도차를 평가하여 현장에 적용 가능한 가열코일의 위치 및 개수 등의 유도가열조건을 결정하였다.
