Abstract: PROBLEM TO BE SOLVED: To equalize the horizontal deflections of upper and lower work rolls, to enable stable rolling and also to prevent the occurrence of twist in a metallic strip by adjusting the approach angle of the metallic strip to a rolling mill in a direction in which the difference of the deflection between a pair of the work rolls is reduced. SOLUTION: When both the upper and lower rolls are deflected toward the inlet side and the deflection of the upper roll is larger than that of the lower roll, the approach angle of the metallic strip is corrected upward. As a method for measuring the deflection, the deflection is directly measured with a distance sensor or, after measuring the horizontal force applied to the work roll with a load cell which is provided in a chock part, the value is converted taking the rigidity of roll into consideration. For adjusting the approach angle, dedicated elevating/lowering rolls 51, 52 may be provided or an elevating/ lowering device may be added to the part of the guide roller on the inlet side. The elevating/lowering rolls 51, 52 and fixed rolls 61, 62 are made so as to clamp the metallic strip and, by lowering the fixed roll 61 in the prestage under the pass line and it is possible to made into an one-roll type of only the elevating/lowering roll 52.
