Description

Technical Field

[0001] This utility model relates to the field of rolling mill technology, and in particular to a positioning feedback device for work rolls of multi-roll rolling mills. Background Technology

[0002] Chinese patent document CN106140822A discloses a positioning feedback device and its positioning feedback control method for a multi-roll mill work roll. Through a control system and a corresponding positioning feedback device, the roll system is positioned and adjusted after roll changing and before roll contact testing, achieving effective support for the roll system. This includes a transverse cylinder driving a transverse arm along a linear guide to an initial set position, a rotary cylinder driving a rotary arm to a mechanical zero position, a position sensor working with the control system and transverse cylinder to bring the transverse arm to a position with no clearance contact with the rotary arm, and a load sensor working with the control system and an adjustment device located at the center line of the fixed arm to adjust the transverse arm, driving the transverse arm, rotary arm, and side support roll box to achieve the set value of the load difference on both sides. This results in strong resistance to eccentric loading, high roll system stability, and high surface quality of the strip after rolling, ensuring stable rolling conditions and continuous rolling.

[0003] The aforementioned devices, including some existing devices, all include structures for control devices. However, these structures are generally fixed on the device, and operators can only operate from fixed points, which is not flexible enough.
