Problems solved by technology

[0002] At present, it is adjusted manually or by airflow non-contact eddy current measurement or plate-shaped roller. The manual operation is completely dependent on experience, which has limitations and wastes manpower. The parameters are not suitable, and the wave shape of raw materials cannot be completely corrected at high and low speeds, and the response speed is slow

Abstract

The invention relates to a method for automatically adjusting the steel plate profile of a temper mill by relying on the parameter setting of the profile meter. The bending of the work roll is used to control the C2 defect wave shape. To eliminate the C4 defect wave shape; if the intermediate roll bending reaches the limit value of 100KN ~ 700KN, CVC roll shifting roll bending will eliminate the C2 defect wave shape; , intermediate roll bending, and CVC values ​​are all reset to 0, only the inclination value remains unchanged; when the width difference between the front and rear strips is less than 100mm, all values ​​remain unchanged; when manual intervention is performed, the automatic shape adjustment function of the shape roll will freeze After 0.5 seconds, control again. After using the set parameters, the rate of product degradation and rejudgment caused by the strip shape wave shape is reduced by 50%, and the adjustment response speed of the shape meter is increased by 30%.

Description

technical field [0001] The invention relates to a method for automatically adjusting the strip steel plate shape of a tempering machine relying on the parameter setting of a shape meter. Background technique [0002] At present, it is adjusted manually or by airflow non-contact eddy current measurement or plate-shaped roller. The manual operation is completely dependent on experience, which has limitations and wastes manpower. The parameters are not suitable, and the raw material wave shape cannot be completely corrected at high and low speeds, and the response speed is slow. [0003] Among them, the non-contact eddy current measurement of the air flow or the adjustment of the shape roller is the feedback adjustment mechanism. After the actual shape of the strip is measured, the skin tempering machine automatically adjusts the shape of the strip according to the set target shape curve. [0004] The plate shape vector uses the Chebyshev polynomial to fit the current plate sh...
