SIMULATION OF QUENCHING PROCESS BY NUMERICAL HEAT TRANSFER MODEL

Abstract

In quenching process many parameters have an effect on this process such as steel type, quenching medium type, quenching medium temperature and the volume of the workpiece. In order to give a workpiece free of defect, it’s very important to understand the effect of these parameters on this process. In the present work a mathematical heat transfer model have been used to simulate the heat treatment (quenching process). This model used to investigate the temperature distribution in the workpiece at different time. A numerical scheme based on a control volume formulation and a computer program with C++ language was used to solve the set of heat transfer equations. The developed model was used also to evaluate the effect heat treatment parameters such as quenching media, carbon steel type and cross sectional area of the workpiece. The model also can be used to simulate the heat treatment process (quenching process) of various materials and alloys with different conditions. The results of the model were compared with experimental published data give good agreement.
