A method of recycling aluminum scrap by using a molten salt having a larger specific gravity than a liquid phase of aluminum, the method comprising:
- separating a phase of a molten material of an aluminum-containing component included in the aluminum scrap from a phase of the molten salt containing impurities included in the aluminum scrap.
An apparatus for recycling aluminum scrap, comprising:
- a melting furnace containing a molten salt having a larger specific gravity than a liquid phase of aluminum;
- a funnel-shaped container having a tubular portion placed into the molten salt;
- a charger for charging a molten material of aluminum scrap into the funnel-shaped container;
- and
- a cooler for cooling the molten material of the aluminum scrap charged into the funnel-shaped container so that impurities included in the aluminum scrap crystallize, and then the crystallized impurities fall into the molten salt.
An apparatus for recycling aluminum scrap, comprising:
- a cooler for cooling a molten material of aluminum scrap so that solidification after impurities included in the aluminum scrap crystallize yields a solidified material;
- a melting furnace containing a molten salt having a larger specific gravity than a liquid phase of aluminum;
- and
- a charger for charging the solidified material into the molten salt,
- the melting furnace heating the solidified material charged into the molten salt so that an aluminum-containing component included in the aluminum scrap melt and floats on the molten salt.
An apparatus of recycling aluminum scrap, comprising:
- a melting furnace having a bottom and containing a molten salt having a larger specific gravity than a liquid phase of aluminum and aluminum melt in this order from the bottom;
- and
- a charger for charging aluminum scrap into the aluminum melt,
- the melting furnace heating the aluminum scrap charged into the aluminum melt so that an aluminum-containing component included in the aluminum scrap melts, and impurities included in the aluminum scrap fall into the molten salt.
