Embodiment Construction

[0042] FIG. 1 shows a schematic perspective view of an aluminum-comprising honeycomb body 1 with laminated metal sheets 2 wound in an S-shape. The honeycomb body 1 has channels 5 formed using smooth and corrugated metal sheets 2 . The channels 5 and the metal foils 2 form a corresponding honeycomb structure 3 . The honeycomb structure 3 is surrounded by a tubular jacket 6 which protrudes beyond the end face 7 of the honeycomb body 1 . Here, the open end faces 26 of the individual channels 5 are arranged substantially within the flat end faces 7 of the honeycomb body 1 .

[0043] The production of the aluminum-comprising honeycomb body 1 shown includes, for example, the following steps:

[0044] - selection of at least partially structured aluminum-based foils;

[0045] - stacking and S-winding the at least partially structured metal sheets to form a honeycomb structure 3 with channels 5 extending substantially parallel to the axis 4 (not shown);

[0046] - inserting the me...

Abstract

The invention relates to a method for producing an aluminum-comprising honeycomb body (1), comprising the steps of: selecting at least partially structured aluminum-based metal sheets; stacking and / or winding the at least partially structured metal sheets (2 ) to form a honeycomb structure (3) containing channels (5); by means of at least one radiant heater (8) heating the metal sheet (2) from the open end face (26) of the channel (5), the honeycomb structure (3) in At least one zone (9) is heated such that the at least one zone (9) is in a temperature range of about 450° C. to about 600° C. after about 2 seconds to about 30 seconds; 9) The metal sheets (2) are connected together by bonding technology.

Description

technical field [0001] The invention relates to a method for producing an aluminum-comprising honeycomb body, in which at least partially structured metal foils (Metallfolies) are laminated and / or wound to form a honeycomb structure with channels extending essentially parallel to the axis, the metal foils being at least Partially embedded in the tubular casing and connected to each other at least in the subregions using joining techniques. Such metal honeycomb bodies are used, for example, as catalyst supports for purifying exhaust gases of internal combustion engines. Background technique [0002] Known honeycomb bodies, in particular metal catalyst supports, have a honeycomb structure with thin-walled, smooth and / or corrugated metal sheets wound, for example, in a helical or S-shape, in a cylindrical or elliptical cylinder The tube-shaped shells are connected to each other by welding, brazing, sintering, bonding and other joining techniques. [0003] In order to increase...
