Method for removing pinch roll at outlet of head roller way

The embodiment of the invention provides a method for removing a pinch roll at an outlet of a head roller way, and relates to the technical field of electrical automation control. The problem that a pinch roll cannot be dynamically adjusted according to the size of a rolled piece, and consequently pinch faults are likely to occur is solved. The method comprises the following steps: acquiring a pinch roll no-load torque; the preset torque of the pinch roll, the head position of the rolled piece, the target position of the rolled piece, the actual torque of the pinch roll and the actual speed Vact of the pinch roll are obtained; according to the head position of the rolled piece, the target position of the rolled piece, the actual torque Tact of the pinch roll and the no-load torque T0 of the pinch roll, the upper roll is controlled to move close to the lower roll in stages; and according to the actual torque Tact of the pinch roll, the preset torque Tset of the pinch roll, the actual speed Vact of the pinch ro
