محدود کردن نیرو در تغییر رانش محوری ورق آسیاب

The paper considers operation of the CVCplus roll axial shifting and Work Roll Bending (WRB) systems of plate mill horizontal stand. It provides arrangement of hydraulic equipment providing operation of these systems. It considers the functional diagram of the backup bending force control system. The authors mention shortages of the design algorithm for backup bending setting. They propose the improved system algorithm. They provide results of experiments with forces in the CVC and WRB hydraulic cylinders under conditions of roll axial shifting during implementation of these algorithms. Technical efficiency of the proposed solution is verified: roll durability is improved due to reduced friction forces at axial shifts.
