Material Control System For Cold Rolled Steel Sheets And Method For Generating Material Prediction Model For Cold Rolled Steel Sheets

Abstract: A material control system for cold rolled steel sheets, according to an embodiment of the present invention, comprises: a programmable logic controller that obtains process data about already produced cold rolled steel sheets; a process controller that controls a manufacturing process of cold rolled steel sheets according to the process data from the programmable logic controller; a model generation unit that learns a set of learning data in advance and generates a prediction model for predicting a longitudinal material of a cold rolled steel sheet to be produced; and a production management system that transmits and receives information to and from the process controller, receives a prediction value from the prediction model generated by the model generation unit, and manages production of the cold rolled steel sheet being produced. A method for generating a material prediction model for cold rolled steel sheets, according to an embodiment of the present invention, comprises the steps of: generating, by a model generation unit, a set of learning data; and training a preset model with the set of learning data to generate a prediction model for predicting a longitudinal material of a cold rolled steel sheet to be produced, wherein a plurality of pieces of data included in the set of learning data include: hot rolling process data from among process data provided from a programmable logic controller; material data and composition data provided from a production management system; and data mapping measurement positions between cold rolling process data and annealing process data from among the process data from the programmable logic controller, and the process data provided from the programmable logic controller may be process data about the produced cold-rolled steel sheet, which is obtained in advance by a sensor.
