METAL SECTOR HAVING A CURVED INNER SURFACE AND COLD CRUCIBLE INDUCTION MELTER COMPRISING SAME

摘要

The present invention relates to a metal sector and a cold crucible induction melter comprising same, and the cold crucible induction melter according to the present invention comprises a wall, which is formed by insulating a plurality of sectors made from a metal material with an insulation material, wherein the sectors comprise an inner curved surface that protrudes inwardly thereby forming the inner surface of the wall, an outer flat surface portion which forms the exterior of the wall, and a side flat surface for connecting the curved inner surface and the outer flat surface, thereby effectively preventing the generation of an electric arc and improving driving efficiency of the melter.
