A control system for regulating the flow of liquid metal in a device for casting a metal. A detector measures a process variable. A control unit evaluates data from the detector. At least one process parameter is automatically varied in order to optimize casting conditions. The detector measures a characteristic of the meniscus at at least two points on the meniscus instantaneously throughout the casting process.

Control system, computer program product, device and method

A method and a device for continuous or semi-continuous casting of metal. A primary flow (P) of hot metallic melt supplied into a mold is acted upon by at least one static or periodically low-frequency magnetic field to brake and split the primary flow and form a controlled secondary flow pattern in the non-solidified parts of the cast strand. The magnetic flux density of the magnetic field is controlled based on casting conditions. The secondary flow (M, U, C C c c G G g g O O o o ) in the mold is monitored throughout the casting and upon detection of a change in the flow, information on the detected change monitored flow is fed into a control unit ( ) where the change is evaluated and the magnetic flux density is regulated based on this evaluation to maintain or adjust the controlled secondary flow.
