| description | To provide a molten metal cleanness inspection method capable of detecting inclusions over a whole surface of a broken surface so as to enable a molten metal cleanness inspection with high precision.SOLUTION: A molten metal cleanness inspection method is the method for inspecting molten metal cleanness and includes the steps for: pouring molten metal into a casting mold so as to obtain a casting; dividing the casting by breaking means so as to obtain an observation piece; photographing a broken surface of the observation piece so as to obtain a broken surface photographed image; evaluating the broken surface photographed image by a model generated with the use of deep layer learning so as to detect inclusions present on the broken surface; and evaluating the molten metal cleanness from an area of the broken surface and the number of the detected inclusions.SELECTED DRAWING: Figure 1
【課題】破断面の全面に渡って介在物検出が可能であり、ひいては高い精度での溶湯清浄度検査を可能とする金属溶湯清浄度の検査方法を提供すること。【解決手段】金属溶湯清浄度の検査方法は、金属溶湯清浄度の検査方法であって、鋳型に金属溶湯を流し込み、鋳物を得る工程と、前記鋳物を破断手段により分割し、観察片を得る工程と、前記観察片の破断面を撮影手段により撮影し、破断面撮影画像を得る工程と、深層学習を用いて作成したモデルが、前記破断面撮影画像を評価することにより、前記破断面に存在する介在物を検出する工程と、前記破断面の面積と検出された前記介在物の数から溶湯清浄度を評価する工程と、を有する。【選択図】図１ |
