Abstract
This invention relates to an improved method of melting metal, particularly reactive metals, such as aluminum, wherein heated molten metal is withdrawn from a first chamber and a portion of the withdrawn molten metal is transferred to a second chamber containing solid metal so as to melt same and a portion of the withdrawn metal is recirculated to the first chamber so as to maintain melt homogenuity therein.
Claims10
A method of melting metal comprising
- a. maintaining a body of molten metal in a heating chamber;
- b. withdrawing molten metal from said heating chamber;
- c. pumping a portion of said withdrawn molten metal to a melting chamber containing solid metal so as to melt said solid metal;
- d. pumping a portion of said withdrawn molten metal to said heating chamber so as to maintain a substantially homogeneous melt in said heating chamber;
- and
- e. returning molten metal from said melting chamber to said heating chamber.
