Abstract
A method of controlling vertical folds during casting includes determining a fold control parameter of a skim dam of a casting system. The method also includes introducing molten metal into a mold cavity of a casting mold of the casting system and forming a molten sump while controlling the skim dam to have the fold control parameter. A skim dam system for a casting system includes a skim dam and a control system for selectively controlling a skim dam submergence depth of the skim dam in a molten sump.
Claims20
A method of controlling vertical folds during casting, the method comprising:
- determining a fold control parameter of a skim dam of a casting system;
- and
- introducing molten metal into a mold cavity of a casting mold of the casting system and forming a molten sump while controlling the skim dam to have the fold control parameter.
A skim dam system for a casting system, the skim dam system comprising:
- a skim dam;
- and
- a control system configured to selectively control a skim dam submergence depth of the skim dam in a molten sump.
A DC casting system comprising:
- the skim dam system of claim 23;
- and
- a casting mold for receiving molten metal in the molten sump, wherein the skim dam is positionable within the casting mold.
A casting system comprising:
- a plurality of casting molds for receiving molten metal;
- a plurality of skim dams, wherein each skim dam is positionable within a corresponding casting mold;
- and
- a control system configured to jointly control a skim dam submergence depth of each skim dam in a molten sump in the corresponding casting mold.
