A ROLLING MILL FOR ROLLING PLATE AND STRIP WITH ROLL DEFLECTION CONTROLLED BIDIMENSIONALLY

Abstract A rolling mill for rolling plate and strip with roll deflection bi-dimensionally with high precision in which its rolls are automatically supported in two dimensions at their mid-portions for controlling their flexures, comprising a housing (10), cluster of rolls (1 and 21, 2 and 22, 3 and 23, 4 and 24) and roll chocks (6 and 26, 8 and 28). Said chocks consist of mid-chocks, side chocks (6, 26) which are horizontally sliceable and middle supporting means there between. In order to minimize the flexible deflection of the rolls during rolling, the rolling mill of present invention is further provided with a bi-dimensionally mid-supporting automatic system, which is comprised of the housing (10), the chocks, a first mid-supporting means between the mid-chocks (8) and the side-chocks (6), a second mid-supporting means between the housing (10) and the chocks (8), a third mid-supporting means between the housing (10) and the side-chocks (6). Said mid-supporting means comprise a screwdown means (9), horizontal supporting blocks (29), vertical supporting blocks (5, 25) and supporting blocks between the mid-chocks and the side-chocks. With such structure of the rolling mill, the flexible deflection of the rolls is significantly suppressed, thereby reducing the deviation of the rolled strips or plates in the cross-sections.
