Title:
A ROLLING MILL WITH ROLL DEFLECTION BI-DIMENSIONALLY CONTROLLED
Document Type and Number:
WIPO Patent Application WO/2000/051754
Kind Code:
A1
Abstract:
A rolling mill with high precision in which its rolls are automatically supported in two dimensions at their mid-portions for controlling their flexibility, comprising a housing, cluster of rolls and roll chocks. Said chocks consist of mid-chocks, side-chocks which are horizontally slidable and middle supporting means therebetween. 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, the chocks, a first mid-supporting means between the mid-chocks and the side-chocks, a second mid-supporting means between the housing and the chocks, a third mid-supporting means between the housing and the side-chocks. Said mid-supporting means comprises a screwdown means, horizontal supporting blocks, vertical supporting blocks 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.
