Zusammenfassung:PROBLEM TO BE SOLVED: To enable high efficiency rolling by eliminating the gap between a roll chock and a cross head or a housing, improving horizontal direction toughness and suppressing mill vibration. SOLUTION: Work rolls 14, 15 are as facing respectively journaled with upper/lower work roll chocks 12, 13 of a housing 11, a screw down device 20 to act a prescribed pressure for the upper work roll 14 is arranged in the upper part of the housing 11, screw mechanisms 23, 31, which press respective work roll chocks 12, 13 in the horizontal direction, are arranged at the inlet side or the outlet side of the housing 11, further, hydraulic cylinder mechanisms 24, 32, which press respective work roll chocks 12, 13 in the horizontal direction, are arranged at the other side, a flow throttle part 46 is arranged in a hydraulic supply/discharge tube 45 of the hydraulic cylinder mechanisms 24, 32.
