Способ изготовлени спеченного сотового элемента

摘要

A method for producing a metallic honeycomb configuration is described. The method includes forming a honeycomb body by stacking and/or winding layers of steel sheet containing chromium and aluminum resulting in the honeycomb body having channels through which a fluid can flow. The honeycomb body is introduced into a tubular jacket. Connections are formed between neighboring layers of steel sheet by thermal treatment. The honeycomb body is then cooled down. It is preferred for the layers of steel sheet to be provided with a rolling oil having a high carbon content before the forming of the honeycomb body, with the effect that a layer of carbon enhancing the sintering process is formed in the thermal treatment. The number of connections produced in individual regions can be further influenced by selective introduction of stresses or by stress relief.
