Based on the continuous development of industrial smart manufacturing and the wide appli-cation of cloud-edge-end and digital twin technologies,the digital twin structure and key technologies for hot rolling production based on cloud-edge-end were proposed.Among them,the three-layer archi-tecture in the digital twin structure realizes the digital management and intelligent control of hot roll-ing production and equipment.The key technology of hot rolling digital twin is the data communica-tion between equipment based on 5G+edge computing technology.At the same time,the cloud-edge-end technology of data processing,storage and computing modeling is combined to solve the problems of low speed and poor privacy security of direct communication between physical entity and cloud.Fi-nally,the hot rolling digital twin system is gradually constructed.
