Abstract
A method for producing aluminum-containing honeycomb bodies includes providing at least partly structured aluminum-based metal foils. The at least partly structured metal foils are stacked and/or wound to form a honeycomb structure having passages. The metal foils are heated from an open end face of the passages with at least one radiant heater. The honeycomb structure is heated in at least one subregion in such a way that the at least one subregion has a temperature between approximately 450° C. and approximately 600° C. after approximately 2 seconds to approximately 30 seconds. The metal foils are connected together in the at least one subregion by technical joining.
Claims20
A process for producing aluminum-containing honeycomb bodies, which process comprises the following steps:
- providing at least partially structured metal foils based on aluminum;
- at least one of stacking or winding the at least partially structured metal foils to form a honeycomb structure with passages having an open end face;
- heating the metal foils with at least one radiant heater from the open end face of the passages, to heat the honeycomb structure, at least in a subregion, and cause the at least one subregion, after approximately 2 seconds to approximately 30 seconds, to have a temperature of approximately 450° C. to approximately 600° C.;
- and
- connecting the metal foils to one another by technical joining in the at least one subregion.
