METHOD FOR SETTING ROLLING CONDITION FOR COLD ROLLING MILL, COLD ROLLING METHOD, METHOD FOR MANUFACTURING STEEL SHEET, DEVICE FOR SETTING ROLLING CONDITION FOR COLD ROLLING MILL, AND COLD ROLLING MILL

WIPO Patent Application WO/2024/018665

A1

In this method for setting rolling conditions for a cold rolling mill, a prediction model is generated by using, as an explanatory variable, first multi-dimensional data which includes three-dimensional steel sheet information including outside the pass-line of a material to be rolled on the entrance side of the cold rolling mill and which is obtained by converting past rolling performance data into multi-dimensional data, and by using, as objective variables, the control amount of a steering roll and a screw-down position of the cold rolling mill. Said method comprises a step for estimating at least one among the control amount of the steering roll and the screw-down position of the cold rolling mill by inputting, into the prediction model, second multi-dimensional data generated from the three-dimensional steel sheet information including outside the pass-line of the material to be rolled on the entrance side of the cold rolling mill.
