Abstract

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Gussteils (6) einer thermischen Turbomaschine mit einem bekannten Gussverfahren. Zwischen einer Modellform (9) und einem keramischen Einsatz (2) befinden sich an dem keramischen Einsatz (2) Vorsprünge (3), wobei die Vorsprünge einen Winkel (α, β) zwischen der Mittellinie (10) und der Aussenkante der Vorsprünge (3) von kleiner 30° besitzen und wobei die Vorsprünge (3) sowohl zur Fixierung des Einsatzes (2) während des Gussverfahren als auch zur Reduktion des Kerbfaktors in den Aussparungen (8), welche am Gussteil (6) entstehen, dienen.

Figure 00000001
The invention relates to a method for producing a casting (6) of a thermal turbomachine using a known casting method. There are projections (3) on the ceramic insert (2) between a model form (9) and a ceramic insert (2), the projections forming an angle (α, β) between the center line (10) and the outer edge of the projections (3 ) of less than 30 ° and the projections (3) serve both to fix the insert (2) during the casting process and to reduce the notch factor in the recesses (8) which are formed on the casting (6).
