| Abstract: | The principle of water elutriation process was discussed.The water flowing velocity was calculated by ceramic dropping velocity in the water by means of the frictional numeral groups method, and the maximum size of FGH95 alloy powder elutriated was determined under certain water flowing velocity. In order to justify the efficiency during the water elutriation process of separating ceramic inclusions from FGH95 alloy powder, the maximum theoretical and experimental size of FGH95 powder elutriated was compared at different water flowing velocity. |
