CONTROL APPARATUS FOR COOLING OF STRIP

摘要

PURPOSE: A strip cooling control system is provided to rapidly solve a problem of the curved state of a strip by properly cooling the upper and lower parts of the strip passing through a run-out table, thereby preventing accidents. CONSTITUTION: A strip cooling control system includes a displacement measuring unit (11), an air curtain unit (12), and a control unit (20). The displacement measuring unit radiates lasers to a strip passing through a run-out table, thereby measuring the distances to an edge portion and to the central portion of the strip. The control unit measures the curved state of the strip based on the distances inputted by the displacement measuring unit and controls a spraying unit (30) according to the curved state of the strip.
