<p>The present invention relates to a method for controlling a rolling force of a skin pass mill in a correction process. In a correction process of improving the flatness of a coil, an elongation rate is constantly maintained by adjusting the rolling force of the skin pass mill based on the rolling speed, and thus the inaccuracy of the elongation rate measured based on the difference between rotation amounts of deflect rolls is solved, thereby preventing rapid variations in the rolling force. Since the rolling force is controlled by a relationship between the rolling speed and the elongation rate, the variations in the elongation rate are minimized to improve the mechanical property and the flatness of the coil.</p> |
