A computer program product for controlling an apparatus for continuous
casting of metals. The computer program product includes a computer
readable medium and computer program instructions recorded on the
computer readable medium executable by a processor for performing the
steps of supplying a molten metal to a casting mold with an elongated
horizontal cross section, applying at least one magnetic field to the to
exert an influence on the movement of the molten metal, generating a
stationary magnetic field with a variable strength across the elongated
cross section of the casting mold in the vicinity of, or below, where the
molten metal is supplied, and generating a variable magnetic field in an
area of the upper surface of molten metal in a region that is centrally
located with respect to the elongated cross section and in the vicinity
of where the molten metal is supplied.
