Problems solved by technology

[0005] The purpose of the present invention is to provide a four-high reversing rolling mill equipped with an automatic centering device for the strip. The actual position of the strip during the rolling process can be directly displayed on the HMI (human-machine interface), which solves the need to look at it with the naked eye. Eliminate the problem of distinguishing or measuring with a tape measure, and at the same time improve the accuracy and referenceability of the control, greatly reduce the operator's operating intensity, reduce operating risks, improve rolling stability and reduce rolling accidents

Abstract

The invention discloses a four-roller reversible mill provided with a strip automatic centering device and a rectifying method thereof. An actual position of a strip in the rolling process can be directly displayed on a HMI, so that the problem of needing to distinguish by eyes or measure by tapes is solved, meanwhile, the control accuracy and the reference capacity are improved, the operation difficulty of operators is largely reduced, the operation risk is reduced, the rolling stability is improved, and the rolling accidents are reduced.

Description

technical field [0001] The invention relates to a four-roll reversing rolling mill equipped with an automatic strip centering device and a deviation correction method thereof. Background technique [0002] The automatic strip centering device (CPC) is mainly composed of a photoelectric detection head, a high-frequency light source transmitter, a digital electronic controller, a linear position sensor, an electro-hydraulic servo valve and a hydraulic station. CPC is a continuous closed-loop adjustment system. The detection head continuously measures the position changes on both sides of the running strip, and the position deviation signal of the strip is input to the digital electric controller for data processing; the output value of the electric control system and the hydraulic control The station’s electro-hydraulic servo valve is connected; after the position deviation signal is electro-hydraulic converted, the servo valve drives the hydraulic cylinder to drive the uncoil...
