Embodiment Construction

[0025] See figure 1 As shown, the present invention discloses a two-way deviation correction control system for cold-rolled strip steel. The cold-rolled strip correction control system consists of a strip deviation detection device, a correction angle calculator A, a reverser, a forward and reverse selector, an oil cylinder position detection device, an actual correction angle calculator B, a proportional integral Regulators, servo valves and cylinders form a continuous closed-loop system. The deviation of the strip is measured by the detection device of the deviation of the strip, and the value is converted into an electric signal and input into the angle calculator A to be corrected, and the angle to be corrected is calculated. When the strip runs in the forward direction, the forward and reverse selector is selected as forward, and the angle to be corrected is directly input into the forward and reverse selector. When the strip runs in reverse, the forward and reverse sel...

Abstract

The invention provides a cold-strip steel bidirectional deviation correction control system which is a continuous closed-loop system formed by a strip steel deviation detection device, an accrued deviation correction angle calculator A, a reverser, a forward/reverse selector, an oil tank position detection device, an actual deviation correction angle calculator B, a proportional integral regulator, a servo valve and an oil tank. The system realizes the control function of bidirectional deviation correction of the strip steel.

Description

technical field [0001] The invention relates to a deviation correction control system for cold-rolled strip steel, in particular to a deviation correction control system for cold-rolled strip steel with bidirectional deviation correction function. Background technique [0002] In the production of cold-rolled strip steel, due to the camber defects of hot-rolled raw materials and the wear of the strip passing rollers, the strip is prone to deviation. Therefore, in the cold-rolled strip processing line, a deviation correction control system is generally installed to Correct the strip so that it is on the center line of the unit. [0003] At present, the research on the deviation correction control system focuses on the deviation correction analysis of the forward running of the strip, and proposes a deviation correction method, but does not involve the deviation correction of the strip running in the reverse direction. However, in the actual production process, due to equipme...
