To overcome this issue, a TGAL hybrid model combining a Temporal Convolutional Network (TCN), Graph Convolutional Network (GCN), Multi\u2010Head Attention mechanism, and Long Short\u2010Term Memory (LSTM) network is proposed for multi\u2010step accurate prediction of furnace temperature. The method first applies wavelet denoising to suppress noise in the industrial data collected by the SCADA system and employs the Pearson correlation coefficient to select highly correlated features, thereby improving the quality of the input data. The proposed TGAL model exploits the synergy of TCN in capturing long\u2010term temporal dependencies, GCN in uncovering spatial correlations among variables, the attention mechanism in dynamically weighting features, and LSTM in temporal dynamic modeling. Validation on 44,640 one\u2010minute data samples from actual production shows that, compared with traditional models, the proposed model achieves maximum improvements of 7.44% in RMSE, 24.85% in MAE, and 25.27% in MAPE for 2\u2010step prediction, respectively. For 10\u2010step prediction, the improvement rates remain at least 4.23% in RMSE, 6.91% in MAE, and 6.31% in MAPE. Moreover, Diebold\u2013Mariano statistical tests confirm that the TGAL model's predictive accuracy is significantly superior to that of the comparison models. Nevertheless, the model performance under extreme operating conditions remains limited by data noise and nonlinear dynamics, and the physical mechanisms of the smelting process have yet to be incorporated. To address these limitations, future work will focus on dynamic coupling modeling and the embedding of physical information to further enhance the model's generalization capability and physical consistency.<\/jats:p>","DOI":"10.1002\/cpe.70623","type":"journal-article","created":{"date-parts":[[2026,3,8]],"date-time":"2026-03-08T14:24:47Z","timestamp":1772979887000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Multi\u2010Step Temperature Prediction for a\n                    <scp>TGAL<\/scp>\n                    Regenerative Aluminum Smelting Furnace"],"prefix":"10.1002","volume":"38","author":[{"given":"Hao","family":"Jiang","sequence":"first","affiliation":[{"name":"School of Electrical and Information Engineering Zhengzhou University of Light Industry  Zhengzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-3747-4623","authenticated-orcid":false,"given":"Lingfei","family":"Shen","sequence":"additional","affiliation":[{"name":"School of Electrical and Information Engineering Zhengzhou University of Light Industry  Zhengzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ningbo","family":"Li","sequence":"additional","affiliation":[{"name":"School of Electrical and Information Engineering Zhengzhou University of Light Industry  Zhengzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,2,23]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.egypro.2019.01.849"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.applthermaleng.2018.09.060"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/s25061946"},{"key":"e_1_2_11_5_1","first-page":"1","article-title":"Analysing the Role of Physics\u2010Informed Neural Networks in Modelling Industrial Systems Through Case Studies in Automotive Manufacturing","volume":"13","author":"Ciampi F.
