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.

摘要： Molten metal can be introduced into a liquid sump during direct chill (DC) casting, such as DC casting of aluminum, through a feed tube having a nozzle with an opening. The opening of the nozzle can be shaped and/or sized to generate a jet of molten metal within the liquid sump. The jet of molten metal can exhibit Reynolds number at or above a threshold amount. Such a jet can achieve improved metallurgical properties over standard casting techniques, such as improved grain refinement. A sufficiently high Reynolds number can be achieved by supplying the molten metal at a sufficiently high velocity. When supplying molten metal at a constant volumetric flow rate (e.g., to avoid fluctuations in casting speed), the nozzle can be crafted to have a smaller-than-standard diameter opening, thus generating a higher-than-standard velocity jet.

摘要： A liquid metal jet supplying molten metal during a direct chill casting operation can be optimized to erode the slurry region of the molten sump, but not the solidified metal, at a rate equal to the casting speed. A model of the erosion of solidifying grains in the slurry region of the molten sump can be non-dimensionalized to be used to generate casting parameters (e.g., optimally sized nozzle openings and optimal molten metal flow rates) that would provide the optimized liquid metal jet during the casting process. An ingot cast using such an optimized liquid metal jet would have improved macrosegregation properties (e.g., reduced macrosegregation or more evenly distributed macrosegregation), such as having ingot solute concentrations varying from the molten metal supply concentration approximately 10% or less or 5% or less across the width or height of the ingot.
