Abstract: Driven by the global energy transformation and the "double carbon" goal, green low-carbon continuous casting technology has become the core path of emission reduction in the iron and steel industry. This paper systematically reviews the key technologies of electromagnetic metallurgy, near net shape continuous casting and rolling (ESP, MCCR), waste heat recovery, high casting speed and so on, and reveals the potential of energy saving and carbon reduction through solidification control, short process integration, intelligent scheduling and hydrogen energy substitution. The results show that the integrated application of these technologies can significantly reduce the energy consumption and carbon emissions of the continuous casting process, and promote the development of the steel industry in the direction of high-efficiency, intelligence, and greenness. In the future, it is necessary to deeply integrate digital technologies, hydrogen energy substitution technologies, and circular technologies, break through the bottlenecks in large-scale applications, and provide theoretical support and technical solutions for the low-carbon transformation of the steel industry.
