Abstract
A method for adding alloying material to a molten metal media, such as molten aluminum, is disclosed. The method includes converting the alloying material into a spray of superheated alloy material and directing the spray into the molten metal media at a depth below the media's surface to enhance dissolution and dispersion of the alloying material in the molten media.
Claims15
A process for adding a material to molten media, said process being capable of adding said material in substantial quantity, comprising the steps of:
- (a) providing a chamber having a discharge positioned within said molten media;
- (b) introducing into said chamber a gas comprising an ionizable gas under sufficient pressure to maintain an interior molten media surface substantially at said chamber's discharge region;
- (c) providing a plasma within said chamber, the plasma substantially extending at least from said interior molten media surface to a site within said chamber and spaced from said interior media surface;
- (d) supplying to said site within said chamber said material in molten form and converting said material into superheated spray substantially within said plasma and carried toward said interior molten media surface;
- and
- (e) conducting a gas from said chamber into said media to aid entry of said material into said media.
A process for adding a material comprising a first metal to molten media comprising a second metal, said process being capable of adding said material in substantial quantity, comprising the steps of:
- (a) providing a chamber having a discharge positioned within said molten media;
- (b) introducing into said chamber a gas comprising an ionizable gas under sufficient pressure to maintain an interior molten media surface substantially at said chamber's discharge region;
- (c) providing a plasma within said chamber, the plasma substantially extending at least from said interior molten media surface to a site within said chamber and spaced from said interior media surface;
- (d) supplying to said site within said chamber said material in molten form and converting said material into superheated spray substantially within said plasma and carried toward said interior molten media surface;
- and
- (e) conducting a gas from said chamber into said media to aid entry of said material into said media.
