THEORETICAL
STUDY OF AN OSCI-LLATING WAVEFORM
FUNCTION AND
PARAMETERS FOR
CONTROLLING
THE
NON-SINUSOIDAL OSCILLATION
OF A MOLD
Abstract: A new non-sinusoidal
oscillation waveform is constructed for controlling the mold
oscillation during continuous casting. Casting velocity and
oscillation parameters are then established for a computer model
of the continuous casting process. The waveform distortion
coefficient e of waveform function is close to the waveform
distortion rate a, so e is taken for a when the basic parameters
are selected initially. The waveform function can be created for
the servo hydraulic system or the mechanical driving system. Industrial scale experiments show the waveform function is effective.
