摘要： 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.

摘要： Techniques are disclosed for reducing macrosegregation in cast metals. Techniques include providing an eductor nozzle capable of increasing mixing in the fluid region of an ingot being cast. Techniques also include providing a non-contacting flow control device to mix and/or apply pressure to the molten metal that is being introduced to the mold cavity. The non-contacting flow control device can be permanent magnet or electromagnet based. Techniques additionally can include actively cooling and mixing the molten metal before introducing the molten metal to the mold cavity.
