摘要:
A technique has been developed for fabricating electromagnetic induction coils in a reproducible manner. The process utilizes a split mandrel that can be disassembled to remove the mandrel from the coil. The technique has increased coil production rates by a factor of 8 over the freehand winding method. The success rate for producing a functional levitation coil has been increased from 50% to 95%. The levitation coil designed during this work has successfully levitated and melted a variety of alloys including Cu, Ag, Ag–Ni, Cu–Fe, Fe–C, and Nb–Ge. W was also levitated but not melted at temperatures as high as 2700 °C. The highest sample melt temperature achieved was 2400 °C for the Nb–Ge samples.
