Document Type and Number:
Japanese Patent JP4226884
Kind Code:
B2
Abstract:
A metal catalyst carrier has a core comprising a corrugated sheet (11) and a flat sheet (12) with a plurality of slots (11a, 12a) in a shape elongated in a direction perpendicular to a cell passage direction. The slots (11a) are formed before a sheet metal is corrugated and have predetermined intervals (X, Y) apart from one another. The plural slots (11a) disposed along the direction perpendicular to the cell passage direction are arranged to form a plurality of slot arrays arranged in the cell passage direction, and an interval Y in the cell passage direction and an interval X in the direction perpendicular to the cell passage direction, between the opening peripheral edge portions of the slots (11a) adjacent to each other in the slot arrays adjacent to each other, are set under the conditions satisfying X ≥ 0 mm and X ≥ -(5/2)Y + 10 mm, thereby preventing the occurrence of distortions and cracks in the process of corrugating the sheet metal.
