Roll for rolling mill

One kind of rolling mill rolls used, comprising: disposed in the linear region of the central portion of the roll of the drum, disposed in the sub-roll crown control region both end portions, is provided in the linear region of the sub-roll crown control of the main roll crown between the control region region. Rolling the outer surface of the roller cylinder, generatrix in the linear region is inclined with respect to the drum axis straight, while the main roll crown control region is formed of rapid convex curves and concave curves, is formed flat in the sub-roll crown control region convex curve and concave curve, and the drum is substantially equal to the diameter of the roll at both ends. Thereby, the outer curved surface of the drum roll degree of freedom, the control amount of the roll crown, factors causing less vibration plate.
