| Outline of Final Research Achievements |
Fundamental studies to develop high speed aluminum metal melting technology using HTS coils were performed in this study. A numerical model to analyze the induction heating of aluminum metal by rotating it in DC magnetic field was developed. The heating experiment of aluminum specimen was done and the temperature increase of the aluminum specimen was measured. It was shown that the numerical results were well agree with the experimental results. A test device for aluminum metal melting by the induction heating using HTS coils was designed using the numerical electromagnetic and thermal analysis. The results of electromagnetic design illustrated the feasibility of HTS coils using the commercial HTS wire. The time-varying reaction magnetic field due to the eddy current in the aluminum material was analyzed. The numerical results showed that, by placing the electromagnetic shield, the reaction magnetic field could be reduced to the level not to affect the stability of HTS coils.
