摘要：
A new levitation-melting apparatus with flux concentration cap is developed to get a stable levitation. The cap is also a concentrator that has a slit and a hole. In this paper, the relationship between the diameter of the cap's hole and the high-frequency power is measured, and the flux distribution of this apparatus is investigated by using the approximate-axisymmetric boundary element analysis including the terminal voltage. As a result, it is shown that this apparatus is useful to stationary levitation. In this system, it is not necessary to control so carefully the exciting current for a light weight sample.
