Non-contacting molten metal flow control

Systems and methods are disclosed for using magnetic fields (e.g., changing magnetic fields) to control metal flow conditions during casting (e.g., casting of an ingot, billet, or slab). The magnetic fields can be introduced using rotating permanent magnets or electromagnets. The magnetic fields can be used to induce movement of the molten metal in a desired direction, such as in a rotating pattern around the surface of the molten sump. The magnetic fields can be used to induce metal flow conditions in the molten sump to increase homogeneity in the molten sump and resultant ingot.

Transferring molten metal from one structure to another

A system and method for transferring molten metal from a vessel and into one or more of a ladle, ingot mold, launder, feed die cast machine or other structure is disclosed. The system includes at least a vessel for containing molten metal, an overflow (or dividing) wall, and a device or structure, such as a molten metal pump, for generating a stream of molten metal. The dividing wall divides the vessel into a first chamber and a second chamber, wherein part of the second chamber has a height H2. The device for generating a stream of molten metal, which is preferably a molten metal pump, is preferably positioned in the first chamber. When the device operates, it generates a stream of molten metal from the first chamber and into the second chamber. When the level of molten metal in the second chamber exceeds H2, molten metal flows out of the vessel and into another structure, such as into one or more ladles and/or one or more launders.

Vibratory System And Method For Molten Steel Transfer
20240165698 · 2024-05-23 ·

A vibratory system and method for use in transferring molten metal. The vibratory system includes a vibrator which generates vibrational energy used to dislodge particulate positioned in a ladle for storing molten metal in an industrial molten metal transfer and manufacturing process. In one example, the vibratory system includes a transfer device for guiding the molten metal from the ladle and the vibrator is connected to the transfer device. In an example of a method for dislodging the particulate from the ladle, particulate is added to the ladle and vibrational energy is applied or transferred to the ladle to dislodge the particulate from the ladle allowing a flow of the molten metal to exit the ladle unobstructed by the particulate.
