Abstract

A depressing position setting method for rolling a plate capable of increasing the dimensional accuracy of a product and eliminating troubles with passing of plate due to a meandering and camber by reflecting, on a depressing set position, an accurately considered variation in mill stretch amount after inclusion of the tip of a rolled plate and a variation in plate thickness and a plate thickness wedge resulted from the variation thereof based on the predicted values of thrust forces produced in rolls during the rolling, comprising the steps of predicting, before starting the rolling, thrust forces between the rolled plate and operating rolls produced during the rolling, individually setting, based on the predicted values of the thrust forces, the depressing position at both time points when the rolling is started and when thrust reactions produced at the support points of the thrust forces are stabilized, setting, during the rolling, the plate at the depressing position when the rolling is started before the start of the rolling, monitoring the stability of the thrust reaction after the start of the rolling, and re-setting the plate, at the time point when the thrust reaction is judged stable, at the depressing position at the time point when the thrust reaction is stabilized.
