摘要

In the chattering detection method of the cold rolling mill according to the present invention, the first multidimensional data generated based on the one-dimensional arrangement data showing the past rolling results of rolling the rolled material by the cold rolling mill is used as an explanatory variable. By inputting the second multidimensional data generated based on the conditional data corresponding to the array data related to the rolling target material to the prediction model learned with the past chattering occurrence record corresponding to the rolling record as the objective variable. , Includes steps to predict the occurrence of chattering during rolling of the material to be rolled.
