Abstract In this paper, the development and application of hot delivery and charging, direct rolling and endless rolling technology of casting-rolling of billet are introduced with the view of metallurgical process engineering. Taking the process of billet continuous casting and rolling as an example, the key elements which influence the energy dissipation of the process were studied and the key technologies to realize "laminar flow" operation of material flow, energy flow and information flow in the typical dissipative system of the metallurgical process were discussed. Through theoretical analysis and factory examples, it is proved that by optimizing the "interface" connection of continuous casting and rolling, establishing the optimized operation network of material flow, energy flow, and information flow and realizing efficient operation, the energy dissipation of the whole process can be significantly reduced, a large number of energy sources can be saved, to realize cost reduction, efficiency increase, energy conservation, and emission reduction, and green production.

Key words： metallurgical process engineering continuous casting-rolling "Interface technology" hot transfering and hot charging direct rolling continuous casting-endless rolling
