Setting Automated Roll Axial Shifting Control System of Plate Mill
Abstract The paper provides the CVC plus system designed for control of cross-section and sheet flatness of the 5,000 mm plate mill stand at OJSC Magnitogorsk Iron and Steel Works. It considers principles of roll axial shifting and spindle horizontal balancing. It describes designs of correlated systems of automated roll and spindle position control. The authors offer oscyllograph records reflecting system settings. Their coordinated functioning is proven to provide a constant gap between the roll and spindle under conditions of rolling and setting between passes. The oscyllograph records provided confirm efficiency of the spindle position control system with automated switching to force control in the hydraulic cylinder.
