SUMMARY:Digital twin simulation of material and plant for hot rolling
DESCRIPTION:"This paper presents a web-based system that describes the interaction of a hot rolling mill and the rolled material. It represents a combined digital twin simulation of the plant and the product in terms of temperature-time deformation behavior resulting from the specific rolling schedule of a customer-specific plant, be it e.g., a hot strip mill, thin-slab casting and rolling facility, Steckel- or heavy plate mill. This tool is combined with a model to describe the microstructure evolution of the processed material. The physical description of the material is based on evolution equations for the austenitic phase regarding recrystallization, grain growth, precipitation of various compounds as well as austenite decomposition including a prediction for as-rolled mechanical properties for the cold material based on the phenomenological description of well-known strengthening mechanisms and their combination for multi-phase steels. The description of the interaction between process equipment and product is considered by using derivates of in-house design models that have precise parametrizations for mechanical as well as thermal interaction with the processed material. Extensive information computed on forces, torques, temperatures, throughput, and microstructural information as well as predictions on capability constraints are available via corresponding visualization including proper export functionality for the generation of e.g., reports. In this way the user is in the position to gain detailed insight in the hot rolling process, e.g. the analysis of already produced materials or performing what-if analysis to acquire information on upcoming products in a development cycle.
The computation facilities are hosted by Primetals Technologies. Customer access is established via a standard web browser and customer Know-How is fully protected by using high level state-of the art security mechanisms."
