Title: Crucible for floatation dissolution
Inventor: TAKE TATSUO
IPC: F27B14/04
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To facilitate assembling to insulate heat between the crucible heat inner wall and molten bath by forming an electrically insulated layer, by flame spraying, on a facing surface to an adjoining segment with a longitudinal copper- made segment arranged in a peripheral direction to constitute a crucible. SOLUTION: Both side surfaces, adopted as surfaces opposite to the segments 5 adjoining a longitudinal copper-made segment 5, prevent the short circuit between the adjoining segments 5 formed of an electrically insulated layer 7, by frame spraying ceramic, e.g. aluminum. Moreover, an insulator hardly fuses, even if it comes into contact with molten bath, by the stronger electrically insulated layer 7, so that it is prevent from mixing into the molten bath. It is preferable that a thermal insulating layer is formed on a surface, for forming the crucible inner peripheral surface of the longitudinal copper-made segment 5, by fuse spraying, and moreover the thermal insulating layer is composed of material doubling as the electrically insulated layer 7.  Forming the thermal insulating layer insulates heat to the molten bath, to prevent a short circuit even the molten bath bestridly contacts between the segments 5 by thermal and electric insulation characteristic.
