摘要： Systems and methods may utilize magnetic rotors to heat molten metal in the corner regions of a mold during casting (e.g., casting of an ingot, billet, or slab). The magnetic rotors are positioned adjacent to the corners of the mold and heat the molten metal in the corner region to increase the temperature of the molten metal adjacent the corners. The increased temperature of the molten metal in the mold corners can prevent intermetallics from forming in the molten metal or otherwise reduce such formation.

摘要： A pump system for a metal furnace includes a tank and a magnetic stirrer. The tank includes a tank chamber that is configured to receive a fluid, such as a molten material. The tank is positioned above magnetic stirrer and such that the magnetic stirrer is outside of the tank chamber. The magnetic stirrer includes a rotating permanent magnet configured to generate a moving magnetic field in the molten material in the tank chamber that induces movement in the molten material.

摘要： A direct chill casting mold system includes a mold and at least one coolant bar. The mold defines a casting cavity having a casting axis along which a metal product moves during a casting process. The at least one coolant bar includes a plurality of nozzles, and the at least one coolant bar is configured to dispense a coolant via the plurality of nozzles onto a periphery of the metal product after the metal product has passed through the mold. In various aspects, the at least one coolant bar is movable relative to the casting axis.
