Abstract
An apparatus for melting down chips of, e.g., aluminum into a molten bath of a melting furnace for, e.g., aluminum. A charging vessel (10) is installed in the molten bath (2) of the melting furnace (1), and has an opening (11) kept above the surface (3) of the molten bath, an inlet port (12) through which molten metal (2) flows from the melting furnace (1 ) into the charging vessel (10), and an outlet port (13) located below the surface (3) of the molten bath. A discharge pipe (20) is attached to the discharge side of a pump (30) for conveying the molten metal (2), and has a sidewall provided with an intake port (24) connected with the outlet port (13) of the charging vessel (10) for returning the molten metal (2) into the melting furnace (1) through the discharge pipe (20). The apparatus can realize a drastically improved efficiency in melting chips (5), while preventing the oxidation of the chips (5).
