【Abstract】 Using the numerical simulation model with quasi-three-dimensions and the modified coupled current method presented in the previous work, the influences of structure of cold crucible, the power frequency and the electricity property of melting charge on the electromagnetic field in the levitation melting processes are analyzed, and the fundamentals for the technique design of levitation melting with cold crucible are presented. It is shown that the levitation melting with cold crucible is a self-balanced and self-stable process, and the cold crucible can be segmented into 16-20 sectors for high frequency electromagnetic field and/or 4-8 sectors for lower frequency one. It is also shown that to change the power frequency greatly influences the magnetic flux density on the surface of metallic charge, but for nonmetallic charge, the main influence on the magnetic flux density is the segmented number of cold crucible.更多还原
