摘要:
针对在转炉炼钢过程中传统供氧量预测方法存在领域知识与数据驱动模型割裂的问题,提出一种基于知识与数据融合驱动的转炉炼钢供氧量预测方法。首先,构建三级知识融合模块,将冶金机理嵌入深度学习模型;其次,设计双分支架构协同挖掘工艺特征与跨炉次时序规律;最后,采用某钢厂的实际生产数据进行实验。实验结果表明:相比GBRBM‑DBN、HyGPR、Stacking和BOA‑LGBM等主流方法,在SPHC钢种下供氧量的MAERMSE最高分别降低7.59%和6.80%,准确率(相对误差±5%)达到85.29%;在HRB400E钢种下MAERMSE最高分别降低15.24%和15.13%,准确率(相对误差±5%)达到87.91%,验证了所提方法的供氧量预测能力。
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 production patterns. Finally, actual production data from a domestic steel plant was used for the experiment. The experimental results showed that compared with mainstream methods such as GBRBM‑DBN, HyGPR, Stacking, and BOA‑LGBM, the MAE and RMSE of oxygen supply with SPHC steel grade decreased by a maximum of 7.59% and 6.80% respectively, and the accuracy (relative error ±5%) reached 85.29%. With 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.
