APPARATUS AND METHOD FOR CONTROLLING HORIZONTAL OSCILLATION OF AN EDGE DAM OF A TWIN ROLL STRIP CASTER

摘要

The present invention provides an apparatus and method for controlling the horizontal oscillation of an edge dam of a twin roll strip caster. The apparatus includes an oscillation unit (400) which horizontally oscillates an oscillation plate in accordance with an oscillation waveform so that an edge dam refractory coupled to the oscillation plate horizontally oscillates, a servo valve (509) which outputs the oscillation waveform to the oscillation unit, and a control unit (501) which applies the oscillation waveform to the servo valve, thus controlling the horizontal oscillation of the oscillation unit. The present invention variably controls the amplitude, frequency and waveform of the oscillation depending on casting conditions, and horizontally oscillates an edge dam using the servo valve and a hydraulic cylinder, thus rapidly removing edge skull and suppressing the generation and growth of skull, thereby preventing a casting roll or the edge dam from being damaged.
