Description
Im Zuge der Herstellung von Metallbauteilen, insbesondere von mechanisch und thermisch hochbelasteten Metallbauteilen, ist häufig eine Vorprozeßerwärmung erforderlich, um die Metallbauteile danach beispielsweise mit einer Beschichtung versehen zu können. Das Erwärmen der Metallbauteile und ihre Beschichtung erfolgen in der Regel in einer abgeschlossenen Kammer, häufig in einer Vakuumkammer. Nach der Behandlung der Metallbauteile müssen diese abgekühlt werden, wozu es sich anbietet, die Kammer einfach zu öffnen und die Metallbauteile damit der Umgebungstemperatur auszusetzen. Dadurch wird aber ein unkontrollierter Thermoschock auf die Metallbauteile ausgeübt, weshalb es ratsam erscheint, die Bauteile in der Kammer mit einem inerten Kühlgas, das häufig auch als Quenchgas bezeichnet wird, abzukühlen, indem die Kammer mit dem inerten Kühlgas geflutet wird.In the course of the production of metal components, in particular of mechanically and thermally highly stressed metal components Pre-process heating is often required to the metal components then provided with a coating, for example to be able to. The heating of the metal components and their coating usually take place in a completed Chamber, often in a vacuum chamber. After treating the Metal components must be cooled, which is why offers to open the chamber easily and the metal components thereby exposing to the ambient temperature. This will, however an uncontrolled thermal shock applied to the metal components, which is why it seems advisable to place the components in the chamber with an inert cooling gas, often called quench gas is referred to cool by the chamber with the inert Cooling gas is flooded.

Dadurch lassen sich auch sehr komplex mit sehr unterschiedlicher Masseverteilung gestaltete Bauteile verhältnismäßig schnell unter Vermeidung von Thermospannungen abkühlen, wodurch auch eine bessere Ausnutzung von zur Durchführung des Verfahrens benötigten Behandlungseinrichtungen erreicht wird. Ein weiterer Vorteil ist darin zu sehen, daß durch die gezielte Abkühlung einzelner Bereiche insgesamt eine gleichmäßige Abkühlung des gesamten Metallbauteils eintritt, wodurch sich das erfindungsgemäße Verfahren gut und einfach in ein umfassendes Verfahren mit beispielsweise einer weiteren Wärmebehandlung integrieren läßt.There is a significant advantage of the method according to the invention in that through the targeted supply of inert Cooling gas to the areas of the metal components according to their Mass concentration a reduction of thermal stresses reached in the respective metal component during the cooling process becomes. This can also be very complex with very different mass distribution designed components proportionally quickly while avoiding thermal stress cool down, which also makes better use of Implementation of the procedure required treatment facilities is achieved. Another advantage is that that through the targeted cooling of individual areas as a whole uniform cooling of the entire metal component occurs, whereby the inventive method good and easy in a comprehensive process using for example a further heat treatment can be integrated.
Bei der Durchführung des erfindungsgemäßen Verfahrens kann die unterschiedlich starke Beaufschlagung der einzelnen Bereiche der zu behandelnden Metallbauteile mit dem inerten Kühlgas in unterschiedlicher Weise durchgeführt werden; beispielsweise ist es möglich, durch eine gezielte Anbringung von mehr oder weniger Gaszuführungsdüsen für das inerte Kühlgas in der Nähe der einzelnen Bereiche der Metallbauteile eine unterschiedlich starke Beaufschlagung mit dem Kühlgas zu erreichen. Die Einhäusungen lassen sich mit verhältnismä-ßig wenig Aufwand realisieren, insbesondere dann, wenn sie gleichzeitig zur Halterung der Metallbauteile in der Kammer verwendet werden.When carrying out the method according to the invention the different levels of exposure to the individual areas of the metal components to be treated with the inert Cooling gas can be carried out in different ways; for example it is possible through a targeted attachment of more or less gas supply nozzles for the inert cooling gas near the individual areas of the metal components a different amount of exposure to the cooling gas to reach. The housings can be compared with Realize little effort, especially if you at the same time to hold the metal components in the chamber be used.
Mit dem erfindungsgemäßen Verfahren lassen sich Metallbau-teile sehr unterschiedlicher Ausgestaltung und unterschiedlicher Massenverteilung kühlen. Bei Gasturbinenschaufeln darstellenden Metallbauteilen werden vorteilhafterweise Fuß und Kopfplatte der Gasturbinenschaufeln mit Einhäusungen versehen, da diese Teile im Vergleich zu dem zwischen ihnen liegenden Blatt der Turbinenschaufel eine relativ große Masse aufweisen.With the method according to the invention, metal components can be very different design and different Cool mass distribution. Representing gas turbine blades Metal components are advantageously foot and Provide the top plate of the gas turbine blades with housings, because these parts compared to what lies between them Blade of the turbine blade has a relatively large mass exhibit.

der Bereich 5 den Fuß und der Bereich 7 die Kopfplatte
der Turbinenschaufel; zwischen dem Fuß 5 und der Kopfplatte 7
erstreckt im Falle einer Gasturbinenschaufel das Blatt 8.
Sowohl der Bereich 5 bzw. der Fuß einer Gasturbinenschaufel
als auch der Bereich 7 bzw. die Kopfplatte einer Gasturbinenschaufel
haben im Vergleich zu dem dazwischen liegenden Bereich
8 bzw. dem Blatt relativ große Massen und sind deshalb
mit den Einhäusungen 4 und 6 versehen.To cool the

mit inertem Kühlgas zu beaufschlagen, wie es im Hinblick auf
die Massen der von den Einhäusungen 4 und 6 umgebenen Bereiche
5 bzw. 7 des Metallbauteils 3 zum Erreichen einer gleichmäßigen
Abkühlung erforderlich ist. Berücksichtigt man zusätzlich
das durch das inerte Gas in der Kammer 2 bewirkte
Abkühlen des Bereichs 8 des Metallbauteils 3, dann läßt sich
durch entsprechendes Betätigen der Gaszuführungsregeleinrichtungen
