Data synchronization method for strip steel section of cold tandem rolling mill

Abstract

The invention provides a data synchronization method for the strip steel section of a cold tandem rolling mill. According to the classification on actual measuring values by detection instrument equipment in a cold tandem rolling production line area, all the actual measuring values are periodically and rapidly collected, measuring values in a certain time are subjected to average value processing to generate an image data group photo [], finally the actual measuring value data of the image data group photo [] is synchronized onto the strip steel section via the data synchronization method, a synchronization data group syn [] of the strip steel section is generated, the synchronization data groups syn [] are formed together to be a curve with a strip steel length as horizontal coordinates and an instrument equipment detection value as longitudinal coordinates, according to the curve, the actual detecting data of various spot instrument sensors when each strip steel is rolled by a rolling mill section at any length can be checked, according to the data synchronization, the data in a time zone can be converted onto a space zone, and the generated strip steel section data curve can be taken as a basis for judging the quality defect of the strip steel.

Description

technical field [0001] The invention belongs to the technical field of cold rolling process control, in particular to a method for synchronizing the measured data of strip rolling in a cold tandem mill to the strip length direction. Background technique [0002] At present, after the production of a cold-rolled steel coil in the domestic combined cold-rolling unit, the production technicians generally can only check the various rolling actual value data of the steel coil through the PDA system or the finished product data information in the process control system. The PDA system The data provided to technicians is only various actual rolling data in the direction of the time axis, and the finished product data in the process control system can only be provided to production technicians for all kinds of actual rolling data in a coil The average value and the maximum and minimum values, but when the production technician wants to see the various rolling actual value data corre...
