Metal-made carrier body for exhaust gas cleaning catalyst |
摘要 |
A metal-made carrier body is provided for an exhaust gas cleaning catalyst. The carrier body includes a cylindrical metal casing and a metal-made multi-layered composite body. The composite body has been obtained by superposing one over the ther at least one planar metal band made of a thin metal sheet and at least one corrugated metal band made of another thin metal sheet and then rolling both the bands together into a spiral form, so that the composite body defines many network-patterned gas flow passages along the central axis thereof. The composite body is enclosed within the metal casing. A gas-permeable insert is centrally and axially embedded within the multi-layered composite body of the planar metal band and the corrugated metal band.
