摘要：
In Induction Skull Melting (ISM) Process, the liquid metal suffers the synthesis effects of electromagnetic field, thermal field and flow field. Lorenz force and Joule heat obviously impact the distribution of the thermal and how fields. Optimizing electromagnetic field is the key to better control the process of ISM. In this study, the electromagnetic, thermal and fluid fields during ISM of TiAl alloy are simulated. The effects of ampere-turn, frequency and relative position between crucible and coil on the distribution of thermal and flow fields are numerically studied. The simulation model is verified by experiments and the simulation results are discussed in detail.
