摘要： A physical model identification system according to the present invention first uses actual data sampled from a manufacturing line to learn a statistical model expressing a controlled object in the manufacturing line. Next, this system creates numerical quantity data quantifying an input-output relationship between a registered input variable and a response variable of a learned statistical model. Next, this system identifies a correction coefficient of a physical model such that a relationship, expressed by the numerical quantity data, between the registered input variable and the response variable is maintained. An identified correction coefficient is reflected in the physical model implemented in a calculator controlling the manufacturing line. Accordingly, prediction precision of preset values and control values of the controlled object by a practical model is improved, and a stable operation of the manufacturing line and high quality production become possible.

摘要： In preset calculation, a plurality of cooling banks are set to be feedforward or feedback banks, and each of water injection amounts in these banks is calculated. In cooling history management, a recalculation position for re-executing the feedback calculation is set. In feedback calculation, a temperature correction value for compensating a delay due to a conveyance time period from a position of the feedback bank to a position of a delivery side pyrometer, and a response delay of the feedback bank is calculated, when a segment reaches the recalculation position. In the feedback calculation, each of water injection amounts in the feedback banks that is calculated in the preset calculation is changed for each of segments based on a delivery side temperature target value, a delivery side temperature actual value calculated for each of the segments, a delivery side temperature prediction value that is recalculated, and the temperature correction value.

摘要： In an energy-saving-operation recommending system, a total energy consumption of plural facilities during passage of one material to be rolled through a rolling line is calculated, and the total energy consumption is divided by a width and a length of the material to be rolled before rolling to calculate an energy consumption reference value that defines energy consumption per unit width and unit length of the material to be rolled. The energy consumption reference value is stored in association with a steel grade and a target post-rolling plate thickness of the material to be rolled. An energy consumption reference value corresponding to a steel grade and a target post-rolling plate thickness of a material to be next rolled on the rolling line is obtained. The energy consumption reference value is multiplied by a width and a length of the material to be next rolled to calculate predicted energy consumption.

摘要： The prediction system of strip chew collects and stores first data and second data as adaptive model construction data. The first data indicates the occurrence or non-occurrence of the strip chew in an object rolling path and the occurrence point of the strip chew. The second data includes information on a preceding rolling path and attribute information on an object strip. The system constructs an adaptive model using the stored adaptive model construction data, and stores the constructed adaptive model as an adapted model. The system collects prediction data similar to the second data. Then, the system inputs the prediction data to the adapted model to predict the occurrence or non-occurrence of the strip chew in the object rolling path and all or some of the occurrence points of the strip chew before the prediction object strip reaches the object rolling path.
