摘要： PURPOSE: A pinch roll control method is provided to secure smooth rolling threadability by preventing stopping of the rolling bar, secure surface quality of the rolling bar by preventing inflow of high pressure water into finish mill and increase actual yield by preventing misoperation of defective shaped rolling bar. CONSTITUTION: In a method for controlling an upper pinch roll installed in front of finish mill, the method comprises a step (S51) of calculating distance after sensing input of reference point of rolling bar (admission of head part); a step (S52) of cutting the head part of the rolling bar by operating crop shear if the calculated distance is judged to be a head part cutting position; a step (S53) of driving the pinch roll by operating down a pinch roll up/down cylinder, thereby moving down the pinch roll; a step (S54,S55) of calculating a distance after sensing a reference point output (output of tail part) of the rolling bar passing through the pinch roll; a step (S56) of cutting the tail part of the rolling bar by operating the crop shear if the calculated distance is judged to be a tail part cutting point; a step (S57,S58) of moving up the pinch roll by operating up the pinch roll up/down cylinder after completing output of the rolling bar, and stopping driving of the pinch roll up/down cylinder.
