摘要： PURPOSE:To manufacture stably a steel sheet having a uniform sheet thickness by housing each roll chock of upper and lower rolls in a main housing of a multisage multipass rolling mill and housing each roll chock of intermediate rolls in a subhousing supported by the main housing. CONSTITUTION:In case of rolling a steel sheet 1 by a multistage multipass mill consisting of upper and lower rolls 2, 3 and intermediate rolls 4, 4; a roll chock 5 of the upper roll 2 is supported by a main housing 10 through a rolling-reduction screw 7, and a chock 6 of the lower roll 3 is supported by the housing 10 through a hydraulic cylinder 9, and a balancing cylinder 11 is interposed between both chocks 5, 6. Each of roll chocks 12, 13 of the upper and lower intermediate rolls 4, 4 is also supported by a subhousing 16 through a rolling-reduction screw 14 and a hydraulic cylinder 15. The subhousing 16 is fixed to the main housing 10 through connecting members 17, 18. Because each of the chocks 5, 6, 12, 13 is directly supported at its upper and lower parts by the rolling-reduction screw and the hydraulic cylinder, the sheet position is not deviated even when a rolling force fluctuates, and a steel sheet of uniform sheet thickness is stably manufactured.
