Abstract
PURPOSE: To roll a material with stable flatness by forecasting the flatness from the stress distribution at the rolling, setting rolling conditions based on this and controlling the flatness of the material.
CONSTITUTION: In a cold rolling mill of plural stands, the flatness setting deviation forecasting model which forecasts flatness from the extent of deviation between the broadside distribution of the longitudinal stress of the material near the outlet side of rolling rolls and the target stress distribution for the proper flatness of the material as functions of various rolling parameters in made. Bender force, interstand tension and draft are set and corrected successively from the final stand toward the forestage stand by making use of such forecasting model so that the extent of deviation becomes minimum. Because of this, the material is rolled at the stable flatness.
