ABSTRACT:
The present invention relates to a process and apparatus for controlling an electromagnetic casting system. The process and apparatus utilize at least one sense loop and an electrical parameter relating to the sense loop, e.g. the mutual inductance between the sense loop and a containment inductor, to control during casting the height of the contained head of molten material and/or the ingot size. In a first embodiment, a sense loop is positioned in the air gap between the containment inductor and the outer surface of the forming ingot or the molten metal head, preferably in a location in the vicinity of the liquid-solid interface. In a second embodiment, a plurality of sense loops are used to control the casting system.
