WIPO Patent Application WO/2022/269974

A1

In a method for setting a rolling condition for a cold rolling mill according to the present invention, a prediction model is generated using, as an explanatory variable, first multidimensional data obtained by converting past rolling performance data that includes pre-cold-rolling data for a rolling material at the entrance side of a cold rolling mill into multidimensional data and, as an objective variable, post-cold-rolling data for the rolling material at the exit side of the cold rolling mill, and the method includes: a step for inputting, to the prediction model, second multidimensional data generated from information that includes pre-cold-rolling data for a material to be rolled at the entrance side of the cold rolling mill, and a target rolling condition for the cold rolling mill, and thereby estimating the rolled shape of the material to be rolled at the exit side of the cold rolling mill; and a step for changing the target rolling condition for the cold rolling mill such that the estimated rolled shape satisfies a prescribed condition.
