In the vacuum melting superalloy time, different process parameters obtained in the center of shrinkage shrinkage effect is different, in order to guarantee the quality of the workpiece can make the best shrinkage, you know how to do it?

Tests show that during the solidification of superalloy vacuum casting, the reasonable applied 50Hz, 60A electromagnetic stirring; or to refine and increase the superalloy master alloy ingot equiaxed like to reduce the size of the center Shrinkage and distribution has a significant role, but also significantly reduce the extent of dendritic segregation, so that the intrinsic quality of superalloy master alloy ingot has been significantly improved.
Since the cast superalloy typically contain a variety of alloying elements, and components and more active elements of the content of impurities have strict requirements, so superalloy recommended to use two vacuum casting process, contribute to the perfect cast molding.
