Abstract

A return fine ratio control method is for controlling a sintering process performed in a facility including a sintering machine and a cooler, based on a predicted value of a return fine ratio predicted using a return fine ratio prediction model. The method includes an acquisition step (S1) of acquiring a target value of the return fine ratio and input data for the model including the data relating to the cooler, taking into account a delay time based on a timing at which the return fine ratio can be identified, a return fine ratio prediction step (S2) of predicting the return fine ratio using the input data and the return fine ratio prediction model, and an adjustment amount calculation step (S3) of calculating an adjustment amount of a manipulated variable for the sintering process so as to reduce a deviation between the predicted value and the target value.
