Description
Die vorliegende Erfindung betrifft ein Gehäuse einer Abgasbehandlungskomponente, wie beispielsweise eines Katalysators, eines Adsorbers, eines Filters, einer Partikelfalle oder dergleichen, zum Einsatz in einer Abgasbehandlungsanlage, insbesondere der eines Kraftfahrzeugs.The The present invention relates to a housing of an exhaust treatment component, such as a catalyst, an adsorber, a filter, a particulate trap or the like, for use in an exhaust gas treatment plant, in particular that of a motor vehicle.
Derzeit sind sowohl ferritische als auch austenitische Legierungen als Basis für ein solches Gehäuse bekannt. Derartige Gehäuse müssen insbesondere geeignet sein, eine vorgegebene mechanische Festigkeit auch bis zu Temperaturen bis 800°C und darüber hinaus aufzuweisen, um eine dauerhafte Fixierung auch unter beachtlichen dynamischen Beanspruchungen der Abgasbehandlungskomponente zu gewährleisten.Currently are based on both ferritic and austenitic alloys for a such housing known. Such housing have to be particularly suitable, a given mechanical strength also up to temperatures up to 800 ° C and about that To show a permanent fixation even under considerable to ensure dynamic stresses of the exhaust gas treatment component.
Aufgabe der vorliegenden Erfindung ist es, eine Zusammensetzung für ein Gehäuse einer Abgasbehandlungskomponente anzugeben, das den vorstehend genannten Anforderungen genügt.task The present invention is a composition for a housing of a To provide exhaust treatment component, the above-mentioned Requirements are sufficient.
Diese Aufgabe wird gelöst mit einem Gehäuse gemäß den Merkmalen des Patentanspruchs 1. Vorteilhafte Weiterbildungen des erfindungsgemäßen Gehäuses gehen aus den abhängig formulierten Patentansprüchen hervor.These Task is solved with a housing according to the characteristics of claim 1. Advantageous developments of the housing according to the invention go out of the dependent formulated claims out.
Das erfindungsgemäße Gehäuse einer Abgasbehandlungskomponente umfasst erfindungsgemäß ein Material mit folgender Zusammensetzung:
- – Eisen: 50 bis 60 Gew.-%,
- – Nickel: 16 bis 24 Gew.-%,
- – Chrom: 15 bis 18 Gew.-%,
- – Aluminium: 4 bis 8 Gew.-%,
- – Silizium: 0,5 bis 1,5 Gew.-%.
- Iron: 50 to 60% by weight,
- Nickel: 16 to 24% by weight,
- Chromium: 15 to 18% by weight,
- Aluminum: 4 to 8% by weight,
- - Silicon: 0.5 to 1.5 wt .-%.
Der hier vorgeschlagene Nickel-Aluminium-haltige, austenitische Stahl weist einen relativ hohen Nickelgehalt auf. Diese Zusammensetzung ist insbesondere geeignet, metallische und gelötete Wabenkörper aufzunehmen, da diese ein ähnliches Material umfassen wie die Lotbereiche selbst, so dass insgesamt ein ausgezeichnetes Oxidationsverhalten erreicht wird. Dies gilt insbesondere für den Fall, dass die metallischen Folien mit einem Lotmaterial gefügt werden, das zu einem Lotbereich führt, in dem circa 70 % Nickel, 18 % Chrom und 10 % Silizium anzutreffen sind. Gerade bei der beanspruchten Zusammensetzung treten intermetallische Nickel-Aluminium-Ausscheidungen auf, die die mechanischen Festigkeitseigenschaften zumindest bis hin zu Temperaturen von circa 800°C stark erhöhen, insbesondere gegenüber einem einfachen austenitischen Stahl-Werkstoff, so dass die Wandstärke des Katalysatormantels herabgesetzt werden kann. Durch diese Möglichkeit der Wandstärkenreduzierung ergibt sich zudem die Möglichkeit, solche Gehäuse mit einer Kosten- und Gewichtsersparnis bereitzustellen.Of the here proposed nickel-aluminum-containing austenitic steel has a relatively high nickel content. This composition is particularly suitable to receive metallic and soldered honeycomb body, since these a similar Material include as the solder areas themselves, so that total an excellent oxidation behavior is achieved. this applies especially for the case where the metallic foils are joined with a brazing material, that leads to a soldering area, in which about 70% nickel, 18% chromium and 10% silicon can be found are. Especially in the claimed composition occur intermetallic Nickel-aluminum precipitates on the mechanical strength properties at least up to temperatures of about 800 ° C increase greatly, especially compared to one simple austenitic steel material, so that the wall thickness of the Catalyst shell can be reduced. By this possibility the wall thickness reduction there is also the possibility such housing to provide with a cost and weight savings.
Ein bevorzugtes Gehäuse, bei dem die vorstehend aufgeführte Zusammensetzung bezüglich wenigstens eines der nachfolgenden Bestandteile verändert ist:
- – Eisen: 54 bis 58 Gew.-%,
- – Nickel: 18 bis 22 Gew.-%,

- – Aluminium: 5 bis 7 Gew.-%,
- – Silizium: 0,8 bis 1,2 Gew.-%.
- Iron: 54 to 58% by weight,
- Nickel: 18 to 22% by weight,
- Chromium: 16 to 18% by weight,
- Aluminum: 5 to 7% by weight,
- - Silicon: 0.8 to 1.2 wt .-%.
Damit ist insbesondere gemeint, dass einer oder mindestens zwei der aufgeführten Bestandteile in dem engeren Bereich ausgewählt wird.In order to is meant in particular that one or at least two of the listed ingredients in selected in the narrower range becomes.
Ganz besonders bevorzugt ist ein Gehäuse, bei dem die Zusammensetzung bezüglich wenigstens eines der nachfolgenden Bestandteile verändert ist:

- – Silizium: 1 %,
- Iron: 56%,
- Nickel: 20%,
- - Chrome: 17%
- - aluminum: 6%,
- Silicon: 1%,
Bevorzugt findet das Gehäuse Einsatz mit einer Dicke, die kleiner 1 mm (Millimeter) ist, insbesondere kleiner 0,8 mm. Das Gehäuse dient dabei insbesondere zur Aufnahme eines metallischen Wabenkörpers, der mit dem Gehäuse hochtemperatur-verlötet ist. Dazu kann der Wabenkörper mit metallischen Folien aufgebaut sein, die zumindest teilweise strukturiert sind, so dass für das Abgas durchströmbare Kanäle gebildet sind. Bevorzugt sind alle Folien (mit beiden Enden) umfangsseitig an das Gehäuse angelötet.Prefers finds the case Insert with a thickness that is less than 1 mm (millimeters), in particular smaller 0.8 mm. The housing serves in particular for receiving a metallic honeycomb body, the with the housing high-temperature soldering is. This can be the honeycomb body be constructed with metallic films that at least partially structured are, so for the exhaust gas can flow through channels are formed. Preferably, all films (with both ends) circumferentially soldered to the housing.
