ROLLING MILL STAND FOR THE ROLLING OF DIFFERENT ROLLED STOCK WHICH REQUIRE DIFFERENT ROLLING FORCES

摘要

The invention relates to a roll stand for rolling different rolling stock thatrequires different roll separating forces. The inventive roll stand comprisesworking rolls, back-up rolls, optionally a roll bending device for the workingrolls and optionally a device for adjusting and balancing the back-up rolls,and pairs of adjustment cylinders (3) between the roll stands (1) and thechocks (2). According to the invention, the adjustment cylinders (3) consistof respective telescope cylinders (4), in which a first, concentric cylinder(5) having a large diameter is provided for high roll separating forces and asecond, concentric cylinder (15) having a smaller diameter is provided forlower roll separating forces, thereby avoiding high friction losses.
