Abstract

See full text

A steel-sheet non-plating defect prediction method in manufacturing equipment of a hot-dip galvanized steel sheet which equipment includes an annealing furnace, and a plating device arranged on a downstream side of the annealing furnace, the method includes: predicting steel-sheet non-plating defect information on an exit side of the manufacturing equipment by using a non-plating defect prediction model which is learned by machine learning, the non-plating defect prediction model for which an input data is data including one or two or more parameters selected from attribute information of a steel sheet charged into the manufacturing equipment, one or two or more operational parameters selected from operational parameters of the annealing furnace, and one or two or more operational parameters selected from operational parameters of the plating device, and an output data is non-plating defect information of the steel sheet on the exit side of the manufacturing equipment.
