Snaking control method and serial plate rolling mill equipment line (SNAKING CONTROL METHOD AND TANDEM PLATE ROLLING MILL FACILITY LINE)

摘要

The present invention discloses a serpentine control method for ensuring stable conveyance of a rolled material including a rolling of a leading end in a series rolling operation of a metal sheet and a preheating tandem mill facility heat. There is provided a snaking control method for a rolling mill of two or more rolling mills and a serial plate rolling mill in which a rollable material tension measuring device having a tension detector on a work side drive side and a tension detector on a work side drive side between rolling mills, The position of the conveying member in the width direction of the rolled material at the position of the rolled material tension measuring device is directly detected or estimated at the output of the measuring device at the conveying position, and from the output of the working side and the drive side detector of the rolled material tension measuring device, The difference between the work side and the drive side which actually acts on the rolled material at the position of the rolled material tension measuring device is calculated and the difference between the work side and the drive side is set to zero, And controls the difference between the set values.
