Abstract

The invention is suitable for the field of strip steel cold rolling, and provides an edge portion measurement signal compensation method for a contact type plate-shaped roller. The plate-shaped roller is provided with n piezoelectric sensors. The method includes the steps of calculating measurement areas where the two edges of strip steel are located according to the width of the strip steel and the width of a total measurement area of the plate-shaped roller, determining the piezoelectric sensor A and the piezoelectric sensor B which belong to the corresponding measurement areas, calculating the width coverage rates of the strip steel in the corresponding piezoelectric sensor A and the piezoelectric sensor B, calculating the area coverage rates of the corresponding piezoelectric sensors according to the width coverage rates, compensating for the pressure value measured through the piezoelectric sensor A and / or the piezoelectric sensor B according to the area coverage rates of the corresponding piezoelectric sensors, and calculating the plate shape value of the strip steel according to the pressure value which is compensated for. By means of the method, the width coverage rates of the piezoelectric sensors where the edges of the two sides of the strip steel are located are converted into the area coverage rates, the pressure value of the corresponding sensors is compensated for on the basis of the area coverage rates, and the true plate shape value of the strip steel is obtained through the pressure value which is compensated for.

Description

technical field [0001] The invention belongs to the field of strip steel cold rolling, and in particular relates to a method and a device for compensating a measurement signal of a contact shape roll. Background technique [0002] In order to produce high-quality cold-rolled strip products, some modern cold-rolling enterprises have adopted advanced flatness closed-loop feedback control systems in the production process. The stability and precision of the measurement signal will directly affect the control effect of the entire closed-loop feedback control system. Shape rolls are divided into contact shape rolls and non-contact shape rolls according to whether they are in direct contact with the strip. In comparison, contact shape rolls have high measurement accuracy, reliable measurement signals, and strong signal anti-interference capabilities. Therefore, most of the existing cold-rolled strip shape closed-loop feedback control systems use contact type shape rolls for on-li...
