In the field of hot rolling big data, presence different steel types, specifications, and data heterogeneity poses significant challenges to accuracy stability using single machine learning regression technology for prediction. Therefore, this study proposes a hot‐rolled strip crown prediction method that combines clustering fusion modeling. First, article introduces relevant mechanism designing cluster strategies. The optimal strategy is determined through comparative experiments process parameters, size, main material components as features. Subsequently, K‐Means++ algorithm used effectively training testing datasets based on strategy, generating multiple clusters both datasets. Finally, establishes seven models match most suitable model each cluster, matching between rigorous testing. evaluation shows an R 2 value 0.829 root mean square error 3.974. experimental results show proposed outperforms traditional methods in solving multiclass classification heterogeneity, providing strong support intelligent control future.

Background During the hot rolling process, performance of most control systems gradually degrades due to equipment aging and changing process conditions. However, existing gauge-looper-tension method remain restricted by a lack intelligent parameter maintenance strategies. Methods To address this challenge enhance smart manufacturing capabilities strip rolling, based on digital twin method, paper proposes data-driven optimized for system rolling. First, model is constructed serve as an evaluation optimization platform. Subsequently, relevant data are collected calculate Hurst index identifying controller during process. Additionally, controllers with poor values, crayfish algorithm employed adjusting parameters maximum index. Results A real case steel production was used validate proposed method. Experimental results demonstrate that can effectively recognize state controller. Moreover, after optimizing through (COA), value showed significant improvement. Conclusions The -based capability maintain strategy production. Through increasing from 0.574 0.862.

Abstract In modern hot strip mill control systems, tension is the core function, and its performance will be directly reflected in product quality. A prediction model based on Back Propagation (BP) neural network proposed. To ensure that true value obtained, this paper proposes a four-dimensional judgment mode for contact time between looper steel establishes data set of parameters rolled steel. The traditional BP network, genetic algorithm optimized (GA-BP), whale (WOA-BP) models were used to predict tension, their was evaluated. results show proposed WOA-BP has best effect, with highest decision coefficient 0.9330. At same time, contribution rate each variable studied, showed angle roller force had greatest impact it, consistent physical laws. Propose improvement suggestions influence model.
