Abstract

In order to ensure the size and precision of investment casting turbine blade, it is necessary to take shrinkage compensation of castings into consideration while designing the die cavity model. Traditionally, the method of uniformity compensation is adopted, that is, applying the same shrinkage ratio on any part of the blade; assuming that the only decisive factor of shrinkage ratio is blade alloy material. In fact, due to the different blade cooling rate of each part, the shrinkage deformation is different; and it is closely related to the section size, constraint condition and casting process.
