摘要： [PROBLEMS]
To provide a roll, a rolling mill and rolling method capable of not only effectively correcting the plate crown of a material to be rolled but also reducing the edge drop and preventing a roll from damage caused by the increase of the local line pressure between the rolls.
[MEANS FOR SOLVING PROBLEMS]
A roll crown is formed by a continuous curve having a local maximum point and a local minimum value point where the central region held between the local maximum point and the local minimum point represents one function and the end region from the local maximum point to the nearer roll end represents another function having an inclination of steeper gradient (or having a radius decreasing more sharply toward the roll end) than that of the extension of the function in the central region.

摘要： A roll profile for work rolls is provided for both shape control and free ruled rolling. Each of the work rolls is a roll having one tapered end. Providing starting point of the tapered end of the rolls being origin of coordinates, the curve of respective tapered end is a quartic curve represented by a formula as follows, y(x)=a0+a1x+a2x2+a3x3+a4x4, wherein x∈[0,Le], y(x)∈[0,He].Because transition between the tapered portion and the roll body is smooth, asymmetric deformation due to the difference between abrasion of the upper and lower rolls is elimatated, reducing wedged shape of strip, and reducing unstable rolling due to shifting of roll axle caused by asymmetric strip stresses. Futher As the amount of shift of work roll is a axial shift represented by Shift=B/2+Le-Se-Lw/2 so that box shaped abrasion of prior art roll is eliminated, closed type abrasion of prior art roll is changed into open type abrasion, averaging the abrasion of the rolls, eliminating ‘cat ear’ hole, achieving flat roll type rolling, and fulfilling the requirements of free ruled rolling.
