摘要： PROBLEM TO BE SOLVED: To provide a method and an equipment in which the meander of the rear end of a rolled material is eliminated and the squeezing does not arise. SOLUTION: In this method, the rotational speeds (rolling speed) of a rolling mill stand F1 through which a rear end of a plate material 6 is left unfinished and a work roll 2 of a following rolling mill stand F2 are identically controlled, and also the mutual tension between the rolling stand F1 and the rolling stand F2 is controlled to be zero. The tension difference between the working side and the drive side is made to be state of zero at the point between the rolling stand F1 and the rolling stand F2, and similarly the tension difference between the working side and the drive side is made to be zero at the point between the rolling mill F2 and the rolling mill Fn when the plate material 6 is left unfinished. Thus, the meander of the rear end of the plate material 6 is prevented and the squeezing does not arise.

SOLUTION: On one hand, the target non-flat shape over the entire width of this strip is set and, on the other hand, the nonflat shape which is actually achieved here is detected, the difference is calculated by comparing with a prescribed flat shape and this difference is made so as to become the min. value as small as possible using an adjusting member. A device therefor is provided with work rolls 10, 11, work roll bending devices 13, means for inclining the work rolls and back-up rolls 9 in a state of pairs, zone cooling part 15 for the work rolls, thermal shield parts 18, heating parts for strip edges and cooling parts 16 for strip edges before, inside or after the finish rolling line and lubricating devices for strip edges in the inside of the finish rolling line.

摘要： PROBLEM TO BE SOLVED: To manufacture the extremely thin steel sheet for can, having uniform material and sheet thickness in the width direction of the sheet regardless of an extremely thin and wide width. SOLUTION: A slab is made to a sheet bar by rough rolling, the sheet bar is butted against a preceding sheet bar to join them, and the width tip part of the sheet bar is heated by an edge heater. Next, in at least three stands, continuous finish rolling is performed by pair cross roll rolling to produce a hot rolled steel strip with 950mm in sheet width or over, 0.5 to 2mm in sheet thickness and within ±40μm in crown. And, cold rolling, continuous annealing and skin pass rolling are applied to this hot rolled steel strip. According to circumstances, further a plating treatment is applied to the surface of this cold rolled steel strip. Consequently, the steel sheet with characteristics of 0.20mm in average sheet thickness or below, 950mm in sheet width or over, within ±4% of an average sheet thickness in fluctuation quantity of the sheet thickness in the sheet width direction in the range of 95% or over of the sheet width of the steel sheet, and within ±3 of averagehardness in the fluctuation quantity of hardness (HR30T) in the sheet width direction, is made.
