HIGH ACCURACY ROLLING MILL PROVIDED WITH SYSTEM FOR CONTROLLING ROLL BENDING IN TWO PLANES Russian patent published in 2003 - IPC

FIELD: rolled stock production. SUBSTANCE: high accuracy rolling mill having system for controlling roll bending in two plane includes rolling stand, roll sets and roll bearing assemblies. In order to minimize bending deformation of rolls, rolling mill is provided with two-dimension bearing system including rolling stand, roll bearing units and intermediate bearing unit arranged between stand of rolling mill and roll bearing units. Intermediate bearing unit includes pressing down mechanisms, horizontal bushings and sets of vertical bushings. Such rolling mill provides significant decrease of roll bending. EFFECT: improved design of rolling mill providing lowered thickness error in cross section of rolled sheets and strips. 14 cl, 1 dwg
