Description
本発明の前記目的は、誘導コイルからの誘導加熱により金属を溶解する誘導加熱炉用坩堝であって、金属を収容する耐火物からなる容器状の内側層と、前記内側層の少なくとも側壁部を覆い、誘導加熱により発熱する発熱体からなる外側層と、を備え、前記外側層は、前記内側層の外周面に黒鉛シート、炭素繊維ペーパー又は炭素繊維フェルトを貼り付ける、もしくは、カーボン及び黒鉛からなる群より選ばれる少なくとも１種を主に含むスラリーを前記内側層の外周面に塗布することによって形成される誘導加熱炉用坩堝により達成される。 The object of the present invention is an induction furnace crucible for melting metal by induction heating from an induction coil, wherein a container-shaped inner layer made of a refractory material containing metal and at least a side wall portion of the inner layer are provided. And an outer layer made of a heating element that generates heat by induction heating, and the outer layer is made of a graphite sheet, carbon fiber paper or carbon fiber felt attached to the outer peripheral surface of the inner layer, or from carbon and graphite. It is achieved by an induction furnace crucible formed by applying a slurry mainly containing at least one selected from the group consisting of to the outer peripheral surface of the inner layer .
