Claims

[Scope of claims for utility model registration] 1. Including work rolls, intermediate rolls, and backup rolls,
In a rolling mill in which each of the work roll and the intermediate roll is equipped with an increase bender and a day increase bender, a horizontal bender is provided that deforms the intermediate roll or the work roll in the flow direction of the material to be rolled, and A rolling mill characterized in that the lower intermediate roll or the work roll is bent with respect to each other in an S-shaped curve. 2. The rolling mill according to claim 1 of the utility model registration claim, wherein the body length of the intermediate roll is slightly larger or slightly smaller than the maximum width of the plate width of the material to be rolled, and the roll 1. A rolling mill characterized in that the neck journal portion is long and the rolls are configured to be easily deflected in the flow direction of the material to be rolled. 3 Utility Model Registration Scope of Claim 1 In the rolling mill according to claim 1, the bending force of a bender that bends the work roll and the intermediate roll upward and downward, and the horizontal bender that is installed on the intermediate roll or the work roll. A rolling mill characterized in that the amount of deflection of the S-curve of the rolls is controlled in accordance with rolling conditions such as the width of the material to be rolled by combining the rolls in the width direction.
