Abstract:
In a cluster type split housing type rolling mill, the plate thickness control capability is improved by suppressing decrease in the mill rigidity as small as possible. Two pass line adjusting mechanisms (15, 16) are arranged between the operating side and the driving side outer housings (10, 11) in the upper side of the top inner housing (8) to form a top side supporting means for supporting the upper side of the top inner housing (8) to the outer housings (10, 11) in the operating side and the driving side each at two points in the front side and in the back side with respect to a pass direction using rocker plates of these two pass line adjusting mechanisms (15, 16). Further, two press-down cylinders (17, 18) are arranged between the operating side and the driving side outer housings (10, 11) in the lower side of the bottom inner housing (9) to form a bottom side supporting means for supporting the lower side of the bottom inner housing (9) to the outer housings (10, 11) in the operating side and the driving side each at two points in the front side and in the back side with respect to the pass direction using rocker plates of these two press-down cylinders (17, 18).
