Abstract
This invention discloses an online diagnostic method for seamless steel pipe stacking, belonging to the field of seamless steel pipe rolling technology. The method includes: acquiring rolling force data of the stable rolling sections of each stand; filtering the acquired rolling force data to obtain filtered rolling force data for the stable rolling sections corresponding to each stand; plotting the rolling force curve for each stand with time as the abscissa and the filtered rolling force data of the stable rolling sections as the ordinate; quantifying the concavity and convexity of the rolling force curves of each stand to determine the stacking state of the corresponding stand; and generating corresponding adjustment suggestions based on the judgment results of the stacking state of each stand. This invention can provide effective guidance for on-site operators and control systems to implement targeted adjustments.
