Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Leitschaufelkranzes, insbesondere für eine Gasturbine, sowie einen Leitschaufelkranz.The Invention relates to a method for producing a vane ring, especially for one Gas turbine, as well as a vane ring.
Aus dem Stand der Technik ist es bekannt, mehrere einzelne präzisionsgeschmiedete Schaufeln oder Schaufelcluster herzustellen und diese anschließend zu einem ringförmigen Leitschaufelkranz zu verschweißen. Präzisionsgeschmiedete Schaufeln sind sehr teuer, und das Schweißverfahren ist technisch sehr aufwendig, da die Schaufeln sehr präzise zueinander positioniert werden müssen und insbesondere die Schaufelblätter vor Schweißspritzern geschützt werden müssen. Im Übergangsbereich zwischen benachbarten Schaufeln können Versetzungen der Schaufeln gegeneinander auftreten, wodurch im strömungsmechanisch relevanten Bereich des Leitschaufelkranzes sägezahnförmige Profile auftreten können, die zu strömungsmechanischen Leistungsverlusten führen.Out In the prior art it is known to have several individual precision forged Create blades or blade clusters and then to an annular Weld the ring vane. precision forged Shovels are very expensive, and the welding process is technically very consuming, because the blades positioned very precisely to each other Need to become and in particular the airfoils Protected against spatter have to. In the transition area between neighboring blades can Displacements of the blades occur against each other, causing in fluid mechanics relevant area of the vane ring sawtooth-shaped profiles may occur to fluidic power losses to lead.
Ziel der Erfindung ist es, ein kostengünstiges Verfahren zur Herstellung eines Leitschaufelkranzes zu schaffen.aim The invention is an inexpensive process for the production to create a vane ring.
Die Aufgabe der Erfindung wird durch ein Verfahren zur Herstellung eines Leitschaufelkranzes, insbesondere für eine Gasturbine, mit den folgenden Verfahrensschritten gelöst. In einem ersten Schritt werden Schaufelrohlinge bereitgestellt. Im nächsten Schritt werden die Schaufelrohlinge zu einem Leitschaufelkranz gefügt, und in einem anschließenden Schritt wird der zusammengefügte Leitschaufelkranz nachbearbeitet. Mit diesem Verfahren ist es nicht notwendig, präzisionsgeschmiedete Schaufeln zu verwenden, wodurch die Herstellungskosten reduziert werden. Das Fügen der Schaufelrohlinge, beispielsweise durch Schweißen, benötigt geringeren technischen Aufwand, da beispielsweise Schweißspritzer bei der darauffolgenden Nachbearbeitung auf einfache Weise entfernt werden können. Durch den geringeren technischen Aufwand werden die Kosten des Verfahrens weiter gesenkt.The The object of the invention is achieved by a method for producing a Guide vane ring, in particular for a gas turbine, with the solved following steps. In a first step will be Blade blanks provided. In the next step, the blade blanks joined to a vane ring, and in a subsequent step becomes the merged Regarding the vane ring reworked. It's not like this necessary, precision forged To use blades, thereby reducing the manufacturing cost. The joining the blade blanks, for example by welding, requires less technical effort, since, for example, spatter in the following Post-processing can be easily removed. By the lower technical effort will be the cost of the process lowered further.
Gemäß einer Verfahrensvariante erfolgt die Nachbearbeitung des Leitschaufelkranzes durch elektrochemisches Abtragen.According to one Process variant, the post-processing of the vane ring occurs by electrochemical removal.
Gemäß einer weiteren Verfahrensvariante kann die Nachbearbeitung des Leitschaufelkranzes durch Fräsen erfolgen.According to one Another variant of the method, the post-processing of the vane ring by mill respectively.
Die Nachbearbeitung des Leitschaufelkranzes erfolgt vorzugsweise im strömungsmechanisch relevanten Bereich des Leitschaufelkranzes. Auf diese Weise können die strömungsmechanischen Eigenschaften des Leitschaufelkranzes verbessert werden.The Post-processing of the vane ring is preferably carried out in relevant to fluid mechanics Area of the vane ring. In this way, the fluidic Properties of the vane ring can be improved.
Vorteilhafterweise erfolgt die Nachbearbeitung des Leitschaufelkranzes im Übergangsbereich zwischen benachbarten Schaufeln. Somit werden Versetzungen zwischen benachbarten Schaufeln kompensiert und Sägezahnprofile im Übergangsbereich verhindert.advantageously, the reworking of the vane ring takes place in the transition area between neighboring blades. Thus, dislocations between adjacent ones Buckets compensated and sawtooth profiles in the transition area prevented.
Vorzugsweise sind die Schaufelrohlinge geschmiedet. Dies ermöglicht gute Materialeigenschaften der Schaufeln, beispielsweise aufgrund des Faserverlaufs.Preferably are the blade blanks forged. This allows good material properties the blades, for example, due to the fiber flow.
Gemäß einer bevorzugten Verfahrensvariante werden die Schaufelrohlinge zu einem Leitschaufelkranz zusammengeschweißt. Auf diese Weise ist der Leitschaufelkranz integral verbunden.According to one preferred variant of the method, the blade blanks to a Vane ring welded together. That way is the Leitschaufelkranz integrally connected.
Die Erfindung betrifft des Weiteren einen Leitschaufelkranz, insbesondere für eine Gasturbine, der nach einem oben beschriebenen Verfahren hergestellt wurde.The The invention further relates to a vane ring, in particular for one Gas turbine produced by a method described above has been.
