Abstract

Based on the unique characteristics of data within the BF ironmaking domain, this paper select hearth activity, [Si + Ti], and permeability index (PI) as target parameters to verify the effectiveness of the combination of feature engineering and Stacking algorithm in the field of BF process parameter prediction. Based on the actual production data stored in the enterprise database, this paper takes the actual production problems in the process of BF ironmaking as the application background. Through the combination of feature selection and ironmaking theory, the characteristic variables of the prediction model are selected for the preprocessed BF production data, and the accurate prediction of different machine learning algorithms is realized. The results show that the accuracy of stacking algorithm for classification and regression is more than 90%. The model process has good learning and generalization ability to effectively utilize BF ironmaking data and accurately predict BF process parameters.
