The thermophysical property parameters and alloy phase diagram of the Fe-W alloy were calculated and analyzed by the Jmatpro software, and the initial pouring temperature was determined. The sand mold gravity casting process for Fe-W alloy shielding castings was simulated by finite element analysis software ProCAST. Based on the simulated results, the temperature field and velocity field of filling and solidification process were analyzed, and the shrinkage porosity defect area was predicted. With adding cold irons and adjusting related parameters, the defect areas were successfully transferre...
