Abstract

The casting process design of rotor spider was investigated.The filling process was simulated by using the ProCAST software.Based on the simulated results

the origination of slag inclusion was analyzed

then the gating system with filter and casting process design of chill and riser were proposed to improve the casting quality.Numerical simulation was used to analyze the filling process of the gating system with filter and the casting process of chill and riser design.The results reveal that the gating system with filter can absorb the inclusion and stabilize the liquid flow.The casting process design of chill and riser can improve the feeding effect and eliminate the shrinkage cavity and porosity defects.The production verification by using the optimized technology was carried out

and desirable quality of rotor spider could be obtained

which could meet the technical requirement.
