TEMPERATURE SIMULATION OF ELECTROMAGNETIC CONTINUOUS CASTING OF AZ61 MAGNESIUM BILLETS
A mathematical model of the electromagnetic continuous casting process for magnesium billets has been developed to predict the temperature in the billet and dummy block using Microsoft Visual C++ 6.0 and Finite Difference Method (FDM). The induction heat will heat up the molten metal and influence the temperature field of the billet to some extent in the process of electromagnetic continuous casting. It is very important to predict the amount and the distribution of the induction heat. According to the experimental analysis of temperature distribution in the Mg billet, the induced thermal profile in horizontal and vertical direction was studied. Finally, the power of the induction heating was calculated and incorporated into the calculation procedure of the temperature field Boundary conditions used for the primary, secondary cooling and interfacial cooling between the billet and dummy block were mostly defined based on the literature. By comparing the predicted results with the measured data, it is proved that the programmed model could be used to investigate the casting process. The effects of the casting parameters on the billet temperature distribution were studied, which is helpful to optimize the casting recipe.
