ABSTRACT:
The invention provides apparatus for treating a molten metal or alloy using liquid and solid flux, the invention comprising apparatus for passing the metal or alloy through a column provided with an outlet siphon lined with solid granules and liquid flux, at least a proportion of the granules comprising a solid flux having a melting point which is higher than that of the liquid flux and which is higher than the temperature of the metal to be treated. The solid granules can be introduced in a removable interchangeable cartridge. The invention finds utility in the advanced purification of aluminum-based alloys by elimination of ultimate inclusions.
