- Abstract:
-
Aiming at the problem of the disconnection between domain knowledge and data-driven models in traditional oxygen supply prediction methods in converter steelmaking process, a knowledge and data fusion driven oxygen supply prediction method for converter steelmaking was proposed. A three-level knowledge fusion module was constructed, embedding metallurgical mechanisms into deep learning models. Secondly, a dual-branch architecture was designed to collaboratively mine process characteristics and cross-furnace temporal patterns. Finally, actual production data from a steel plant was used for the experiment. The experiment results showed that compared with mainstream methods such as GBRBM-DBN, HyGPR, Stacking, and BOA-LGBM, the MAE and RMSE of oxygen supply under SPHC steel grade decreased by a maximum of 7.59% and 6.80%, respectively, and the accuracy (relative error ±5%) reached 85.29%. Under the HRB400E steel grade, the MAE and RMSE decreased by a maximum of 15.24% and 15.13%, respectively, with an accuracy (relative error ±5%) of 87.91%, verifying the oxygen supply prediction ability of the proposed method.
