Features of the development of digital twins of thermomechanical steel treatment processes and examples of production tasks solved with their use are considered. The technique of creating digital twins of hot rolling, as well as hot or cold rolling with subsequent heat treatment is described. Adistinctive feature of the digital twin being developed is that in addition to the finite-element model of the process, it must also contain an integral model of structure formation that occurs in the treated steel throughout the process.
