Abstract
A ladle for a molten metal includes a main body having a hollow interior and an opening for receiving the molten metal. The main body has a sidewall with a nozzle formed therein. The nozzle defines an axis of rotation for the main body. The nozzle contacts, seals and is in fluid communication with the mold. The nozzle is configured to deliver the molten metal to a mold when the main body is rotated from a first position to a second position.
Claims7
A method of transferring molten metal to a mold, the method comprising:
- providing a ladle for a molten metal, the ladle including a main body having a hollow interior and an opening for receiving the molten metal, the main body having a sidewall with a nozzle formed therein, the nozzle defining an axis of rotation for the main body and configured to deliver the molten metal when the main body is rotated from a first position to a second position, the axis of rotation lying parallel to the direction that the molten metal is delivered through the nozzle;
- providing a mold having an inlet and a cavity formed therein for receiving the molten metal, the nozzle of the ladle in fluid communication with the inlet, the ladle rotatable about the axis of rotation to deliver the molten metal from the nozzle of the ladle into the cavity of the mold when the ladle is rotated from the first position to the second position;
- filling the ladle with the molten metal;
- placing the nozzle of the ladle in fluid communication with the inlet of the mold;
- and
- rotating the ladle from the first position to the second position to deliver the molten metal from the ladle into the cavity of the mold.
