Description

Verfahren zur Herstellung von Düsen, Schaufeln, Rädern und Trommeln. Bei den bisher bekannten Gasturbinen werden Düsen, Schaufeln, Räder und Trommeln aus geschmiedeten oder gegossenen Materialien (Bronze, Stahlguß, Gußeisen u. a.) oder hochwertigen Legierungen hergestellt, um die infolge der Zentrifugalkräfte und hohen Temperaturen auftretenden großen Spannungen aufnehmen zu können. Es ist bekannt, um der Hitze und chemischen Einflüssen Widerstand zu leisten, Materialien wie Porzellan, Glasarten, Quarz u. a. Mineralien zu verwenden, deren Festigkeit durch eingelegte Tragorgane in Form von Drähten, Drahtnetzen, Platten usw. aus Metall erhöht wurde.Process for the manufacture of nozzles, blades, wheels and drums. In the previously known gas turbines, nozzles, blades, wheels and drums are used made of forged or cast materials (bronze, cast steel, cast iron, etc.) or high-quality alloys manufactured to reduce the impact of centrifugal forces and to be able to absorb high voltages occurring at high temperatures. It is known to withstand heat and chemical influences, materials such as porcelain, types of glass, quartz, etc. Use minerals, their strength by inlaid support elements in the form of wires, wire nets, plates, etc. made of metal was increased.

Die auf diese Art- hergestellten Gasturbinenteile genügen den Anforderungen der Praxis nicht. Die vorliegende Erfindung stellt diese Teile aus einem Eisen- oder Metallgerippe- her, um das feuerfeste Erden oder künstliche Steine unter Druck aufgebracht werden. Dadurch wird erreicht, daß diese Materialien ein möglichst dichtes Gefüge erhalten und ihr spezifisches Gewicht dem der Naturgesteine nahe- oder gleichkommt. Bei diesem Verfahren ist es ferner möglich, zwischen das Traggerippe und die den hohen Temperaturen ausgesetzten Wandungen eine Isolierschicht (Kieselgur, Asbest u. a.) derartig einzufügen, daß die Isolierschicht, -welche gleichfalls unter Druck aufgebracht wird, mit der Außenmaterialschicht eine innige Verbindung eingeht.The gas turbine parts produced in this way meet the requirements not in practice. The present invention provides these parts from an iron or metal frameworks, around the refractory earth or artificial stones under pressure be applied. This ensures that these materials are as dense as possible Maintain structure and their specific weight is close to or equal to that of natural rocks. In this method, it is also possible between the support structure and the walls exposed to high temperatures an insulating layer (kieselguhr, asbestos inter alia) to be inserted in such a way that the insulating layer, which is also under pressure is applied, with the outer material layer enters into an intimate connection.
