Development of Heat Transfer Predicting Model for Cold forging Steel(SCr420) During Quenching Process

냉간 단조용 SCr420 강의 퀜칭 시 열전달 예측모델 개발

Heat treatment is one of the critical manufacturing processes that determine the quality of a product. This paper presents experimental and analytical results for the quench of a ring gear in stagnant oil. The goal of this study is to develop heat transfer predicting model in an overall analysis of the quenching process. Thermal conductivities which are dependant on temperatures and convection coefficients which are obtained by inverse method are used to develop the accurate heat transfer model. The results of heat transfer model have a good agreement with experimental results.
