Meandering reform method and the device null in the continual steel strip process

摘要

PPROBLEM TO BE SOLVED: To prevent occurrence of meandering during continuous threading in a continuous annealing apparatus by a simple means. PSOLUTION: A plurality of parallel horizontal-shaft rolls to each other are arranged on the upper side so as to guide a continuous steel strip is guided by changing the direction in vertical zigzag. In the lower part of them, horizontal-shaft rolls parallel to each other are arranged so as to be situated between above two rolls and one of the lower-side rolls is taken as a control roll 3. The roll is supported rockably around the perpendicular axis by taking the neighborhood of the outer periphery in the middle in the length direction of the roll as a virtual fulcrum. A stand 4 is provided on the lower side of the control roll, a circulate-arcuate rail 5 in accordance with the radius of rocking of the roll is provided on the top of the stand, a movable table 6 which is movable along the rail is placed on the rail and a rocking means 7 is connected to the movable table. A liner 9 which is long and parallel in the axial direction of the control roll is inserted in the lower side of the stand and the stand is inclined on a virtual perpendicular plane which is crossed orthogonally with the axis of the upper roll.
