<p>A process for continuous vacuum purification of a molten metal, which comprises agitating a molten metal (1) in a melt agitation portion (B) in a vacuum treatment chamber having a reduced pressure and being preheated, to thereby vaporize and remove impurities in the molten metal, sending the resulting molten metal from the agitation portion (B) to a melt discharge portion (C) through connecting holes, introducing the molten metal into containers in purified melt recovery chambers (10a)(10b) having a reduced pressure through recovery paths (8a)(8b) connected to the melt discharge portion (C), increasing the pressure in the recovery chambers (10a)(10b) back to atmospheric pressure, and recovering a purified molten metal (9), wherein a plurality of paths and a plurality of recovery chambers connected to respective paths are provided and each of the plurality of recovery chambers is used alternately for receiving the purified molten metal; and an apparatus for practicing the process.</p> |
