Abstract

The invention provides a metal carrier, wherein, the wound final end of the metal carrier is provided with stairs and the metal carrier has no small-chamber shaped local deformation even being pressed into a shell. The metal carrier (1) is produced by superposing a metal flat sheet (3) and a metal corrugated sheet (2) on each other and winding them. The invention is characterized in that at the wound end when the corrugated sheet (2) and the flat sheet (3) are wound, the corrugation height of the corrugated sheet (2) is gradually lowered.

Description

technical field

[0001] The present invention relates to a metal carrier for purifying exhaust gas exhausted from internal combustion engines of automobiles and the like, and a method for producing the same. Background technique

[0002] In the past, as a purification device with a built-in metal carrier, for example, as shown in the cross-sectional view of FIG. housing 102 . In this purification device, a corrugated foil 101a and a flat foil 101b are diffusion bonded, and a case 102 and a metal carrier 101 are brazed, and a catalyst is applied to the metal carrier 101 in this state. Further, diffusers 104 are welded to both ends of the case 102 to serve as inlets and outlets for introducing / leading exhaust gas to the catalyst unit (refer to Japanese Patent No. 2779516).

[0003] In addition, as shown in the front view of FIG. 17 and the enlarged view of the main part of FIG. 18, the metal carrier 101 of the honeycomb structure is formed by alternately stacking strip-shaped...
