Abstract: Wide hot-rolled strip is a core raw material for modern manufacturing,and its efficient large-scale production combined with refined quality management is essential for industrial upgrading. However,the hot rolling process is characterized by strongly coupled multivariable factors,along with limited material information sensing,fragmented data systems,and insufficient automation in critical stages. These challenges hinder the coordinated optimization of product quality,rolling stability,and manufacturing cost. This research systematically reviews recent technological advances,with a focus on progress in the following key areas. In the field of multidimensional material information sensing for hot continuous rolling,robust sensing systems based on machine learning and deep learning have addressed the difficulty of feature extraction under high-temperature and high-noise conditions,substantially improving information acquisition in complex conditions. In the area of multi-zone operational interconnection and edge–end collaboration,the integration of heterogeneous data from multiple sources and the use of dynamic resource allocation mechanisms have eliminated information discontinuities among storage yards,rolling lines,and roll grinding systems,enabling coordinated optimization across regions. In centralized control of multiple rolling lines and regions in hot continuous rolling,intelligent rolling technologies oriented toward reduced manual intervention have been developed by leveraging advanced inspection systems and high-accuracy hybrid modeling,thereby enhancing the compactness and responsiveness of the production process. In cross-business coordination for hot continuous rolling,lean management platforms integrating online prediction,real-time monitoring,and anomaly diagnosis have been established within a deeply integrated cyber–physical framework,driving transformation in production management across multiple business domains. Finally,the paper summarizes current developments and outlines future directions for efficient large-scale production and refined quality management of wide hot-rolled strip.
