PURPOSE: To provide a 14 stages rolling mill with roll arrangement that the capacity to transmit torque is raised and also shape change is difficult to be generated even when rolling load is changed.

CONSTITUTION: This rolling mill is provided with a pair of upper and lower work rolls 2 which are brought into contact with a rolled stock, a pair of right and left 1st intermediate rolls 3 with which those work rolls are supported, a 2nd intermediate roll 4 which is simultaneously brought into contact with a pair of those right and left 1st intermediate rolls, a back-up roll 6 in the middle with which the 2nd intermediate roll is supported and back-up rolls 5 on both right and left sides which are arranged on both right and left sides of the back-up roll in the middle and with which the 1st intermediate rolls are supported. The back-up roll in the middle is made into a divided roll, the back-up tolls on both right and left sides are made into solid rolls and roll arrangement that the ratios of the diameter D2 of the 1st intermediate roll to diameters D1, D4, D3, D5 of other rolls satisfy certain relations is taken.
