8. Abstract : based on equivalent liquid surface descending method ( elsdm ) and isolated melting zone method , a multi - hot - spot and simultaneous shrinkage - feeding method was established to predict the shrinkage cavities of steel casting during solidification simulation . the shrinkage in each hot spot can be simulated and fed dynamically and simultaneously by itself using this method . then two practical steel castings were analyzed by this method
