Crown control device and its control method of hot rolling mill

机译:热轧机的凸度控制装置及其控制方法

摘要

PPROBLEM TO BE SOLVED: To provide a crown control means by which an uniform crown in the longitudinal direction on a material to be rolled is obtained. PSOLUTION: This crown control device includes a setup means 101 for outputting a first manipulated variable of a rolling mill 151 to a desired crown, crown measuring means (170, 171) for measuring crowns which are installed before and behind a rolling mill (151), lock-on timing setting means (140) for setting the timing for locking on the crown, crown lock-on means (111, 121) for storing the crown in a specific part as lock-on crown at this set timing, the control means (112, 122) of the crown in the longitudinal direction for outputting the corrective quantity of the first manipulated variable so that the deviation between the crown measured by the crown measuring means (170, 171) and the lock-on crown is reduced and a manipulated variable calculating means for outputting the second manipulated variable from the first manipulated variable and the corrective quantity.
