APPARATUS AND METHOD FOR CONTROLLING

摘要

According to an embodiment of the present invention, an apparatus for controlling an edge mask of an accelerated cooler comprises first and second distance sensors, a plurality of edge masks, a unit for transferring the edge masks, and a controller. The first and second distance sensors are placed facing each other in the longitudinal direction of a slab transferred by a roller table and sense the distance from the slab. The plurality of edge masks are installed to have pitches corresponding to the pitches between nozzles for jetting a coolant. The unit for transferring the edge masks includes a driving unit to transfer the plurality of edge masks in the widthwise direction. The controller allows the plurality of edge masks to mask the edge part of the slab by transferring control signals for individually controlling the edge masks using the distance measured by the first and second distance sensors.
