Abstract

1401527 Vacuum refining of metal ARDAL OG SUNNDAL VERK AS 14 July 1972 [16 July 1971 5 May 1972] 33066/72 Heading C7D Light metal alloys such as aluminium alloys magnesium alloys or titanium alloys are produced in a vacuum furnace 1A from unrefined metal which is passed along a transfer channel 3, through a porous refractory filter unit 6 and nozzles 2 and into the evacuated chamber 1, the drawing of the molten metal through the nozzle 2 being caused by the low pressure in the chamber 1. The resultant jet from nozzle 2 of the metal passing into chamber 1 promotes a large surface area contact between the metal and its low pressure surroundings thus promoting degassing of the metal. Alloying additions of, e.g. Mg, Mn, Fe, Si may be made to the chamber 1 before the molten metal is drawn in, the resultant bath formed and its agitation by the jet of metal ensuring good mixing of the metal and alloy additions. A non reactive gas may be passed into the chamber 1 to remove sodium vapours and other unwanted removable products of the refining process. The gas may be introduced above the melt bath in the chamber 1 through the melt bath by means of feed holes 8 or feed tubes 7 terminating in each of the nozzles.
