    摘要: Spannrollensatz (3, 4) für eine Richtanlage (1) zum Richten eines Bandes (2) oder für ein Nachwalzgerüst zum Nachwalzen eines Bandes, wobei der Spannrollensatz (3, 4)
    • eine erste Spannrolle (8) mit einer ersten Rollenachse und
    • mindestens eine zweite Spannrolle (9) mit einer zweiten Rollenachse
    aufweist,
    wobei die erste Spannrolle (8) eine Planheitsmessrolle ist, die einen Kraftsensor zum Messen einer auf die Umfangsfläche der Planheitsmessrolle ausgeübten Radialkraft aufweist,
    und ein Antrieb für die zweite Spannrolle (9) vorgesehen ist, mit dem ein Drehmoment um die zweite Rollenachse auf die zweite Spannrolle (9) aufgebracht werden kann,
    wobei
    • entweder die erste Spannrolle (8) antriebslos ausgeführt ist
    • oder ein Hilfsantrieb für die erste Spannrolle vorgesehen ist, mit dem ein Drehmoment um die erste Rollenachse auf die erste Spannrolle aufgebracht werden kann, wobei der Hilfsantrieb für die erste Spannrolle schwächer ausgeführt ist, als der Antrieb für die zweite Spannrolle.

    摘要: A roller leveler is provided in which, even when the number of leveling rolls is relatively small, a pitch of the leveling rolls arranged in a zigzag manner in the carrying direction of a steel plate is capable of being made substantially uniform with a relatively simple structure when the pitch of the leveling rolls used for flattening the steel plate is changed. The roller leveler 1 is provided with a first roll group 2 having first leveling rolls 4 through 7 arranged with a pitch "P1" in the carrying direction of a steel plate, a second roll group 3 having five pieces of second leveling rolls 9 through 13 which are arranged with the pitch "P1" in the carrying direction of the steel plate and are disposed in a zigzag manner with respect to the first leveling rolls 4 through 7, a first retract mechanism 29 for making the first leveling rolls 5 and 6 retract from the pass line "PL", and second retract mechanisms 32 and 33 for making the second leveling rolls 9, 10, 12 and 13 retract from the pass line "PL". The second roll group 3 is provided with third leveling rolls 8 and 14 which are disposed with the pitch "P1" in the carrying direction of the steel plate with respect to the second leveling rolls 9 and 13.

    摘要: A roller leveler (100) includes: a leveling roll unit (20) having a plurality of leveling rolls (6, 8a, 8b) configured to rotate so as to pass a plate (P) while sandwiching and pressing the plate; a pushing cylinder (4a, 4b) provided at each of an entrance side and a discharge side of the leveling roll unit (20), at which the plate enters and is discharged, respectively, and configured to press the plate (P) via the leveling rolls (6, 8a, 8b); and a driving mechanism (15) configured to rotate the leveling rolls (6, 8a, 8b) to pass the plate (P). At least one (8b) of the plurality of leveling rolls (6, 8a, 8b) has a stepped structure, including a lateral center portion (21) with a large diameter, corresponding to a center portion of the plate with respect to a plate width direction, and lateral end portions (22) with a small diameter, corresponding to edge portions of the plate with respect to the plate width direction.

    摘要: Methods and apparatus to monitor conditioning machines for strip material (100) are disclosed herein. An example system includes a plurality of work rolls (302,304,306,308) to process a strip material (100). A first sensor (516) detects a first distance (536) between an upper surface of the strip material (100) and a first reference location and a second sensor (518) detects a second distance (538) between an upper surface of the strip material (100) and a second reference location. A controller (604) determines a difference value between the first distance (536) and the second distance (538) to detect material curvature of the strip material (100).
