Zusammenfassung:The present invention provides a method for sand-casting with externally applied magnetic field. The method comprising: providing a sand mold; setting a first side coil at a first side of the sand mold; setting a second side coil at a second side of the sand mold, corresponding to the first side coil; pouring the casting material into the sand mold; outputting a voltage to form a magnetic field between the sand mold via the first side coil and the second side coil during the solidification of castings; and keeping the output voltage until the solidification of castings is done.
