Zusammenfassung:The present invention relates to the crystallizer for casting under the action of magnetic field and the casting process thereby especially for alloy smelting and casting during the production of permanent rare earth-transition metal-boron magnet. Outside the metal crystallizer, is formed one magnetic field with magnetic force lines in the direction perpendicular to the direction of casting liquid metal. The power is turned on before slow casting and off after finishing casting.
