| Abstract: | The defects in the guide six-vane combination cast by non-shaving precision casting,such as misrun,microshrinkage and crack,were studied.Through the experiments and investigation on processes such as pattern making,shell molding,gating system design,melting and pouring,stripping,and detection method,etc.,the rational and feasible process and parameters were obtained.The guide six-vane combinations that meet the operating requirements were successfully produced. |
