Abstract (en)
[origin: EP3974074A1] A control device for controlling a rolling mill device including a pair of mill rolls disposed on opposite sides of a metal plate includes: a first plate end detection part disposed on an entry side of the pair of mill rolls in a conveying direction of the metal plate and configured to detect a plate end position in a plate width direction of the metal plate at a first position in the conveying direction; a second plate end detection part disposed on an exit side of the pair of mill rolls in the conveying direction and configured to detect a plate end position in the plate width direction of the metal plate at a second position in the conveying direction; and a determination part configured to determine whether tip end tension-free rolling, which is rolling of the metal plate by the pair of mill rolls in a state where an exit-side tension applied to the metal plate is zero, can be started, on the basis of a first plate end position of the metal plate detected by the first plate end detection part and a second plate end position of the metal plate detected by the second plate end detection part.
