Heavy plates are products of global economic relevance. Due to the high requirements for this semifinished product, the trend in heavy plate processing is toward providing ever higher quality steels that, for instance, combine a predefined yield point, good weldability, and, at the same time, predefined toughness properties. Unprecedented quality requirements in steel processing can only be met if technologically relevant parameters, such as temperature, are guaranteed to be kept within a narrow tolerance range during the hotrolling process, one of the most decisive steps within the production chain for heavy plates. Within the heavy plate hot-rolling process, often performed in a reversing four-high mill stand consisting of a pair of work rolls and a pair of backup rolls, various production steps like rolling passes, descaling sequences, and cooling periods, determine the plate's temperature evolution. [1] In parallel, temperature evolution affects the microstructure and, thus, associated physical properties of the final product, such as hardness and toughness. [2] It is, therefore, of utmost importance to consider the evolution of the temperature field inside the heavy plate as a specification when planning the entire process that reaches from the slab's exit from the furnace to the last pass.All in all, the production steps of hot rolling govern the plate temperature in two fundamentally different scenarios: sufficiently far from the roll bite, the plate temperature decreases moderately through air cooling or abruptly on the surface of the plate through contact with water which is applied locally in the form of high-pressure jets provided by a water descaling unit. Inside the roll bite, the plastic deformation is accompanied by heat generation inside the plate, and simultaneously the contacting cooler work rolls reduce the temperature at its surfaces. These and other thermomechanical effects can hardly be measured, which is the reason why models are utilized for better insight. As digital transformation has become a significant innovation driver, a digital representation of the process in the form of an integrated digital model, digital shadow, or digital twin has to cover these potentially interfering thermomechanical aspects. [3,4] Modeling and simulation have been integral to the research and development of rolling processes for decades. An incomplete but representative selection of milestones, in chronological order, is intended to outline the road to comprehensive modeling approaches available today: The journey started with basic

Heavy plates are indispensable semi-finished products. Quality is strongly linked with production, so the rolling process must be performed within well-defined narrow tolerances. To meet this challenge, adequate modeling has become a necessity. In contrast to continuous strip rolling, where the workpiece can be modeled as a semi-infinite strip and 2D modeling can be argued quite well, this strategy is insufficient for the comprehensive modeling of heavy plate rolling. The geometry of the heavy plate favors an inhomogeneous distribution of relevant state variables, such as temperature. In addition, if the process involves longitudinal and spreading passes, the required plate rotation spoils the assumption of a symmetric arrangement that might have been acceptable before rotation. Consequently, the derivation of suitably reduced models is not trivial, and modeling tailored to the specific objective of investigation is of utmost importance. Models intended to resolve the evolution of inhomogeneities in the field variables are demanding and computationally expensive. An effective modular modeling strategy was developed for such models to be used offline. Mutually complementing and interchangeable modules may constitute an efficient modeling strategy valid for the specific subject of interest. The presented approach reduces the enormous cost of complete 3D simulation as much as the model purpose allows for.
