Abstract
Apparatus for controlling the oscillations of a mold for continuous casting of metal, the mold being mounted on a table which is connected, in turn, to three spaced apart drives and three load relief springs; three displacement path transducers track each of the drives; a source of reference signals provides reference signals representing the desired oscillation, as to contour, amplitude and rate; actual and reference signals are compared by and in stages which provide correction signals for the drives.
