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.

Mold corner heating during casting

Systems and associated methods are provided for controlling the shape of an ingot head during formation. At the end of a cast, prior to forming the ingot head, chill bars or other cooling structure may be lowered into an ingot mold and define a reduced casting footprint for forming the ingot head. Supplemental molten metal may be fed into the reduced casting footprint, and the chill bars may be moved laterally towards the center of the ingot, further reducing the casting footprint. As additional molten metal fills the reduced mold footprint, the ingot may be lowered relative to the chill bars to further increase the height of the ingot head. Additional molten metal may be added until the desired shape of the ingot head is formed.
