Inventors include Hatakeyama, Daichi; Harada, Akifumi; and Nakai, Yoshie.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: A nitrogen concentration prediction method according to the present invention includes: a prediction step for calculating a predicted value of the nitrogen concentration in molten steel under an operation condition of a prediction object by using a nitrogen concentration prediction model which is a physical model in which a condition of vacuum degassing treatment is used as an input variable and a predicted value of the nitrogen concentration in the molten steel under the condition is used as an output variable; and a correction step for correcting the predicted value of the nitrogen concentration in the molten steel, which has been calculated in the prediction step, by using a machine learning correction model which is a machine learning model in which a condition of the vacuum degassing treatment is used as an explanatory variable, and a prediction error which is a difference value between an actual value and the predicted value of the nitrogen concentration in the molten steel calculated by using the nitrogen concentration prediction model for the condition is used as an objective variable.
