    摘要: Disclosed herein are an apparatus and method for controlling the edge shape of a strip in a twin-roll strip casting process, which improve the quality of the strip by using cameras to photograph the edge portions of the strip being cast by strip casting, analyzing the photographs, and then controlling edge dams according to the edge shape of the strip. The apparatus comprises: an edge dam driving unit which is attached to edge dams attached to both sides of casting rolls so as to control the pressing force of the edge dams against the casting rolls and the upward shift of the edge dams according to the wear and upward shift rate of the edge dams; cameras which are disposed at the strip outlet side of the casting rolls so as to photograph the edge portions of the strip; and a control unit which analyzes the edge shape of the strip from images photographed by the cameras and outputs a signal controlling the wear and upward shift of the edge dams.

    摘要: An apparatus and method for controlling the horizontal oscillation of an edge dam of a twin roll strip caster is provided. The apparatus includes an oscillation unit 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 which outputs the oscillation waveform to the oscillation unit, and a control unit which applies the oscillation waveform to the servo valve, thus controlling the horizontal oscillation of the oscillation unit. The amplitude, frequency and waveform of the oscillation are variably controlled depending on casting conditions. The edge dam horizontally oscillates, 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 edge dam from being damaged.

    摘要: The present invention provides a robust control method for maintaining a melt level at a constant value in a mold in a twin roll strip casting process. In the twin roll strip casting process, whether using a stopper system (3), which is provided in a tundish (2) to supply melt into the mold, or using a camera system, which measures the melt level in the mold, the robust control method of the present invention controls the melt level both using an advanced controller, which controls, at an initial stage of the casting process or when a disturbance arises, the target value of the melt level such that the target level corresponds to the performance characteristics of the melt level control system, and using a feedback controller, which maintains the melt level at a constant value under normal casting conditions.

    摘要: Disclosed herein is a method for drawing a strip initially cast by means of a twin roll strip casting apparatus. The method comprises a roll gap maintenance step where roll gap is maintained, a casting initiation step where a stopper is disengaged from a tundish hole so that molten metal is poured into a space between the rolls, and the rolls are rotated at speed v0 of each of the rolls if the position of the stopper is higher than the actually poured position of the molten metal, a casting speed acceleration step where a roll repulsive force is detected when the molten metal is solidified to the leader strip and passes between the rolls, and the casting speed is accelerated if the roll repulsive force reaches a load threshold, and a normal control step where the casting speed is detected, and if the casting speed reaches a target value.
