Abstract (en)
A process for the degassing, refining or filtering treatment of liquid metals or alloys wherein the metallic liquid is treated with a solid treatment agent. The process comprises the steps consisting of providing the treatment agent in the form of solid granules (10) in a closed container (1) having two counterposed walls in the shape of perforated diaphragms (2a, 2b), with holes having such dimensions as to retain said granules, and having further lateral walls; interposing said container in the pouring channel, at the base thereof; and passing said metallic liquid through said container through said diaphragms to make contact with said treatment agent in said container. An apparatus for performing the process is also described.
