According to the present invention, a device to correct a metal plate comprises: inlet and outlet correction parts having upper and lower asymmetric rolls arranged asymmetrically to each other; and an intermediate correction part arranged between the inlet and outlet correction parts, having upper and lower symmetric rolls arranged symmetrically to each other with a higher torque than the upper and lower asymmetric rolls. The present invention can effectively correct a poor flatness of the metal plate with one pass correction by making the amount of correction larger using a strong torque as the upper and lower symmetric rolls have a larger diameter than the upper and lower asymmetric rolls while being arranged symmetrically to each other, and rotated by a symmetric driving member with a higher capacity than an asymmetric driving member. |
