Abstract

In this paper, the heat transfer coefficient on the A356 alloy METAL-MOULD INTERFACE for HI3 steel and Gray Iron moulds was measured and modeled. Conditions as same as the low-pressure casting conditions were imposed by adding a piston, into the sprue channel. In order to establish one dimensional heat transfer condition, a cylindrical chalky sleeve was placed around of the mould cavity, and then metallic chills (H13 and Gray Iron) are placed at the bottom and the top of the mould cavity. Once purring, the time-temperature (T-t) curves at the interface of chill-mould were saved and plotted by a data acquisition system. Then a mathematical model was introduced for the heat transfer coefficient of the metal mould interface based on the experimental data by utilizing of "inverse heat problems" method. A simulation code of heat transfer was developed by finite difference method (FDM) that it could simulated distribution of heat transfer into at the mold and the cast part. The results of this code showed a sufficient agreement between the simulation and the experimental data.
