Zusammenfassung:To provide a solidified metal ingot separating method capable of removing an ingot of a solidified molten metal so that a steel shell of a molten metal pot causes as less problems as possible, thereby making the molten metal pot easy to reuse.SOLUTION: A solidified metal ingot separating method for separating, from a steel shell, a solidified metal ingot A, which is an ingot of a molten metal solidified so as to be surrounded by a refractory 12 existing inside the steel shell of a molten metal pot 10, comprises a drilling step of forming holes 12a extending from an upper surface to a bottom part of the refractory 12 at intervals over an entire circumference of the refractory 12, and a pulling-up step of pulling up the solidified metal ingot A with respect to the steel shell and separating the solidified metal ingot A from the steel shell.SELECTED DRAWING: Figure 3 【課題】溶融金属用鍋の鉄皮になるべく不具合が生じないように固化した溶融金属の塊を除去することにより、溶融金属用鍋を再利用しやすい状態とすることが可能な固化金属塊分離方法を提供する。【解決手段】溶融金属用鍋10の鉄皮の内方に存在する耐火物12に取り囲まれて固化した溶融金属の塊である固化金属塊Aを鉄皮から分離する固化金属塊分離方法であって、耐火物12の全周に亘って、耐火物12の上面から底部に達するまで延びる孔12aを、間隔を開けて形成する削孔工程と、固化金属塊Aを鉄皮に対して引き上げて、固化金属塊Aと鉄皮とを分離する引上工程とを備える。【選択図】図3
