Abstract

PURPOSE:To enlarge the thickness range of a steel sheet capable of straightening the steel sheet and to perform its optimum straightening by using intermediate rolls arranged between work rolls and backup rolls instead of the drawn out work rolls in accordance with the thickness of a steel sheet. CONSTITUTION:When a steel sheet S is thin, the sheet S is straightened in shape by work rolls 4, 9 shown by the right half in the figure. At that time, the rolls 4, 9 are driven by the frictional forces between intermediate rolls 5, 10 and these rolls 4, 9. When a steel sheet S is a thick one S, the rolls 4, 9 are drawn out to the operation side free from a driving device by a proper means, and the rolls 5, 10 are used as the work rolls as shown by the left half in the figure, to straighten the sheet S in shape. In this case, the work rolls are made small in diameter and the intermediate rolls large, respectively, but the large-diameter work rolls and small-diameter intermediate rolls are also available.

[Prior Art] Conventionally, the same roller leveler has been used to correct the shape of steel plates within a certain thickness range. However, in the case of auxiliary plates, it is necessary to reduce the radius of curvature of the bent part of the steel plate, so it is desirable to use a small diameter roll as the work roll, and in the case of thick plates, the radius of curvature of the bent part is large. It is desirable to use a large diameter roll because it is easy to roll and the rolling reaction force is large. Therefore, in the past, there was a limit to the range of plate thickness that could be corrected by the same roller leveler, and it was not possible to sufficiently correct the shape over a wide range of plate thicknesses.

[Light 1! In the present invention, a work roll and an intermediate roll with different diameters are provided, and in the case of a steel plate of the same thickness, the work roll is used to correct the shape, and when the thickness changes, the work roll is moved to the line. Shape correction is performed by pulling out the intermediate roll and using it as a work roll. Therefore, the range of plate thickness that can be corrected becomes larger, and accurate correction becomes possible.
