<p>The present invention relates to an apparatus and method for controlling oscillation of an edge dam of a twin roll strip caster. The key technical features of the present invention are for an apparatus and method for controlling horizontal oscillation of an edge dam of a twin roll strip caster, wherein the apparatus comprises: an oscillating unit which oscillates an oscillating plate in a horizontal direction in accordance with oscillation waveform so as to permit edge dam refractories coupled to the oscillating plate to oscillate in a horizontal direction; and a servo valve which outputs oscillation waveform to the oscillating unit to achieve the horizontal oscillation, and wherein the method applies oscillation waveform to the servo valve so as to control the horizontal oscillation of the oscillating unit. According to the present invention, amplitude, number of oscillations and oscillation waveform are variably controlled in accordance with casting conditions, and the edge dam oscillates in a horizontal direction using the servo valve and a hydraulic cylinder, thereby quickly removing a skull at the edge dam, suppressing generation and growth of skull, reducing damage to a casting roll or to the edge dam to ensure stability of the casting process, and manufacturing high quality strips.</p> |
