Embodiment Construction

[0024] Below in conjunction with embodiment the present invention is described in detail.

[0025] The measuring sections of the flat rollers are sequentially numbered (1, 2, 3, ..., N) from the operating side to the driving side of the frame, where N is the number of measuring sections of the flat rollers. An array x[i] is initialized according to the width of the measurement section, and its value is the distance from the center of each measurement section to the center of the geometric width of the flat roller.

[0026] There are a total of 33 measuring sections of plate-shaped rollers used in a leveling unit, and each section has a width of 52 mm. The initialization array x[i] is as follows: (-0.832, -0.78, -0.728, -0.676, -0.624, -0.572, -0.52, -0.468, -0.416, -0.364, -0.312, -0.26, -0.208, -0.156, -0.104, -0.052, 0, 0.052, 0.104, 0.156, 0.208, 0.26, 0.312, 0.364, 0.416, 0.468, 0.52, 0.572 , 0.624, 0.676, 0.728, 0.78, 0.832).

[0027] Each time it is judged that a new s...

Abstract

The invention discloses a signal correction method for compensating for bending of a plate-shaped roller. The method is visual and easy to understand, calculation is convenient, the plate shape signal detection precision of the driven plate-shaped roller can be greatly improved, error actions of a control system caused by bending of the plate-shaped roller are avoided, and the plate shape control precision is improved.

Description

technical field [0001] The invention belongs to the field of automatic measurement of steel rolling machinery and equipment, and is suitable for correcting the flatness measurement signal when a driven flatness measurement roll (flatness roll) used for cold-rolled strip steel or other strip products undergoes deflection and deformation Methods. Background technique [0002] During the shape detection process of cold-rolled strip steel, the detection rolls are affected by factors such as large temperature difference, large tension and strong vibration on site, resulting in many noise signals mixed with the original shape signal, and the original shape signal often fluctuates Especially for ultra-thin strips with large aspect ratios, the shape of the strip changes significantly, and slight changes in process parameters may cause large changes in the shape of the strip. [0003] Among the many factors that affect the shape detection signal, the deflection change of the detecti...
