PURPOSE: An apparatus and a method for controlling mistracking of a metal strip are provided to prevent an article from being damaged by rapidly controlling mistracking of the metal strip in on-line. CONSTITUTION: A mistracking control apparatus for a metal strip includes a pair of rolls(11.12) for applying steering force to the metal strip. The rolls(11,12) are moved up and down by means of a lifting device(20). The rolls(11,12) are installed on a swing frame(30), which is rotated by a hinge device. A push-pull device(40) is provided to rotate the swing frame(30) in left and right directions. A driving section(50) applies driving force to the rolls(11,12) so as to synchronize the movement of the rolls(11,12) with a running direction of the metal strip. An amount of displacement of the swing frame(30) is detected by a displacement sensor(60). A detector(70) is provided to detect a mistracking displacement of the metal strip. The swing frame(30), the push-pull device(40), the displacement sensor(60) and the detector(70) are installed on a main frame(80).
