Apparatus for melting down chips
First Claim
1. An apparatus for melting down chips for use with a melting furnace having a bath of molten metal, said apparatus comprising:
- a charging vessel adapted for immersion in the bath of molten metal of the melting furnace, said charging vessel having an opening kept above a surface of the bath, an inlet port through which the molten metal flows from the bath into said charging vessel, and an outlet port located below the surface of the bath;
a pump for conveying the molten metal, said pump having a suction side and a discharge side; and
a discharge pipe attached to the discharge side of said pump, said discharge pipe comprising a sidewall and having an intake port passing through said sidewall and connected with said outlet port of said charging vessel for returning the molten metal to the bath through said pipe.

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).
