Abstract
A skim tool and method for removing impurities from molten alloys in furnaces generally includes a collection portion and an arm. The collection portion has an interior and a blade member having a plurality of apertures configured to capture impurities during application and direct the impurities into the interior. The skim tool further includes a conduit having a first end with an inlet and a second end having a plurality of fingers that extend in various directions along the front side of the blade member. Each of the fingers define an outlet end that are in fluid communication with the inlet. The inlet for receiving a source of nitrogen to be blown through the conduit into the molten metal in the form of a gas.
Claims17
A skim tool comprising:
- a housing having an extending portion and a collection portion, wherein said housing is a hollow structure that houses an arm and a collection member, and wherein said arm is disposed in the extending portion and said collection member is disposed in the collection portion, and wherein said collection portion defines an interior configured for collecting impurities during application, said collection portion defines a front side and a back sides, exterior ends and a lower end, and wherein said collection member is disposed on the front side of the collection portion such that said interior is formed between the collection member and said back side, and wherein said collection member defines a plurality of apertures configured to capture or gather impurities during application and direct the impurities into said interior,
- an extending conduit is positioned on an exterior surface of said arm, said conduit extends along the length of the arm and has a first end that includes an inlet, and a second end having a plurality of fingers that extend in various directions along the front side of said collection member, and wherein each of said plurality of fingers extending to said exterior ends and said lower side of the collection portion.
A skim tool comprising:
- a housing having an extending portion and a collection portion, wherein said housing is a hollow structure that houses an arm and a collection member, and wherein said arm is disposed in the extending portion and said collection member is disposed in the collection portion, and wherein said collection portion defines an interior configured for collecting impurities during application, said collection portion defines a front side and a back sides, exterior ends and a lower end, and wherein said collection member is disposed on the front side of the collection portion such that said interior is formed between the collection member and said back side, and wherein said collection member defines a plurality of apertures configured to capture or gather impurities during application and direct the impurities into said interior,
- a conduit having a first end having an inlet and said conduit including a location where said conduit defines a plurality of fingers that extend in various directions, each of said plurality of fingers extending from said location to said exterior ends and said lower side, each of said plurality of fingers further defining an outlet end, and wherein said inlet is in fluid communication with a source of nitrogen and wherein said inlet is in fluid communications with the outlet end of each of said plurality of fingers.
A skim tool comprising:
- an arm that is in communication with a collection portion,
- said collection portion defines a back side, exterior ends and a lower end, and a blade member disposed in said collection portion such that an interior is formed between said blade and said back side, and wherein said blade defines a plurality of apertures configured to capture or gather impurities during application and direct the impurities into said interior,
- a conduit having a first end having an inlet and said conduit defining a location where said conduit defines a plurality of fingers, each of said plurality of fingers extending from said location to said exterior ends and said lower side, each of said plurality of fingers further defining an outlet end, and wherein said inlet is in fluid communication with the outlet end of each of said plurality of fingers.
