Abstract
In a mold oscillation device for making oscillation of a mold used in a continuous casting machine, an acceleration sensor (22) detects the oscillation to produce an oscillation detection signal representative of said oscillation. The oscillation detection signal has a particular waveform. Responsive to the oscillation detection signal, a signal producing circuit (30) produces an adjusting signal with reference to the particular waveform. With reference to the adjusting signal, a control unit (16) controls the oscillation. In order to produce the adjusting signal, it is preferable that the signal producing circuit carries out a frequency analysis as regards the particular waveform.
