METHOD FOR INSPECTING A COLUMNAR HONEYCOMB MOLDING BEFORE CALCINATION OR AFTER CALCINATION
To provide an inspection method of a columnar honeycomb molding before calcination and after calcination which can be performed in a nondestructive manner, and can be substituted to a rigidity inspection.SOLUTION: There is provided a method for inspecting a columnar honeycomb molding before calcination and after calcination having a columnar honeycomb structure part having an external peripheral side wall, and a bulkhead arranged at an internal peripheral side of the external peripheral side wall, and partitioning a plurality of cells which form a flow passage from a first bottom face up to a second bottom face. The method includes; a process for photographing at least either of images of the first bottom face or the second bottom face of the columnar honeycomb molding before calcination and after calcination by a camera; a process for measuring areas of openings of the plurality of cells in the image; and a process for specifying abnormal cells having openings having areas which allow a deviation from a preset allowable range from the plurality of cells, and measuring the number of the abnormal cells.SELECTED DRAWING: Figure 5
【課題】非破壊で実施可能であり、強度検査に代替可能な焼成前又は焼成後の柱状ハニカム成形体の検査方法を提供する。【解決手段】外周側壁と、外周側壁の内周側に配設され、第一底面から第二底面まで流路を形成する複数のセルを区画形成する隔壁とを備えた柱状ハニカム構造部を有する焼成前又は焼成後の柱状ハニカム成形体を検査する方法であって、前記焼成前又は焼成後の柱状ハニカム成形体の第一底面又は第二底面の少なくとも一方をカメラで撮像し、第一底面又は第二底面の少なくとも一方の画像を生成する工程と、前記画像において、前記複数のセルの開口の大きさを測定する工程と、前記開口の大きさの測定結果に基づき、予め定めた許容範囲から逸脱する大きさの開口をもつ異常セルを前記複数のセルの中から特定し、異常セルの数を計測する工程と、を含む方法。【選択図】図５
