| description | A coupled-field electromagnetic-thermal simulation model was developed to design suitable induction coils for the electromagnetic levitation melting of metals. The model was validated against both analytical solution and experimental observations. Dependence of coil parameters and sample weight (size) on the sample position, temperature and lifting force exerted on sample were assessed. It was found that the cylindrical/flat coils could provide more lifting force and temperature, compared to the conical ones. The more number of coil turns resulted in a higher temperature, but coil overheating may happen. The sample weight should be in a specific range for having a successful levitation process. |
