Process for manufacturing a soldered honeycombed body by using stratified sheet metal |
摘要 |
A process for the production of a brazed honeycomb body with sheets having a layer-like configuration, includes stacking and/or winding sheet metal layers at least partially having a structure for forming passages through which a fluid can flow. At least a portion of the sheet metal layers is initially formed of a layered material having at least one layer of chromium-containing steel and at least one substantially aluminum-containing layer. The aluminum-containing layer is substantially homogenized in a later heat treatment and the heat treatment is effected firstly under a vacuum or in a reducing and then an oxidizing atmosphere. The heat treatment is part of a brazing procedure in which contact locations between the sheet metal layers are brazed together at least in partial regions by the addition of brazing material. |
