Title:
PLATE CROWN CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/203691
Kind Code:
A1
Abstract:
This plate crown control device controls tandem rolling equipment on the basis of an outlet plate crown setting calculation value of each stand as calculated by setting calculation, a mechanical plate crown setting calculation value of each stand, and a bending force and shift position setting value of each stand. A processor calculates a first current learning value on the basis of the difference between a mechanical plate crown observation value and a mechanical plate crown result calculation value. The processor proportionally divides a first learning value by the first current learning value and a smoothing gain and updates the first learning value. The processor, in the next setting calculation and thereafter, calculates the bending force and shift position setting value of each stand by using a corrected mechanical plate crown setting calculation value obtained by adding the first learning value to the mechanical plate crown setting calculation value.
