The invention provides a hot
continuous rolling process monitoring and early warning method based on digital twinning, and relates to the technical field of rolling process intelligent manufacturing.The method comprises the following steps: firstly, establishing a three-dimensional
solid model and a process model of a hot
continuous rolling process at a virtual end; obtaining existing hot
continuous rolling production process data, storing the existing hot continuous rolling production process data into a
database, and establishing a corresponding relationship between the data in the databaseand the three-dimensional
entity model of the virtual end; then calculating by using the process model and utilizing the actual production process data of hot continuous rolling, judging a calculatedvalue, and giving an early warning according to a judgment result; and further storing the hot continuous rolling actual production process data, the process model calculation value data and the judgment result data into a
database, establishing an action corresponding relationship between the hot continuous rolling actual production process data and
virtual production equipment, and carrying outthree-dimensional presentation on the production process at a virtual end, completing the construction of digital twins in the hot continuous rolling process, and continuously performing the digitaltwins according to a fixed communication period until the production of the rolled piece product is finished.
