Abstract (en)
[origin: EP1344589A2] Production of a melt of an alloy for casting comprises: (a) placing the melt having a temperature lying above the liquidus temperature of the alloy in a crystallization vessel (14) heated to a temperature lying below the liquidus temperature; (b) adding an alloy as a powder; and (c) mixing the melt and powder using electrical and/or magnetic forces. An Independent claim is also included for a device for carrying out the process. Preferred Features: The melt is introduced into the crystallization vessel as a beam extending between two electrodes (17, 23) to which an electrical voltage is applied. A magnetic field is formed in the crystallization vessel. The melt is suctioned into the vessel under pressure and with the introduction of a protective gas.
