Abstract：Under the background of the dual carbon policy, enterprises, and scientific research institutes actively carry out low-cost, high-efficiency, and environmentally friendly steel preparation technology. As one of the supporting processes of continuous casting production, cast billets flame cutting has attracted the attention of many enterprises and researchers. Energy-efficient cutting technology and environmentally friendly cutting methods will be the main direction of future flame-cutting development. Based on the actual demand, the cutting principle of flame cutting different combustion media was summarized, the cutting costs, cutting quality (cutting gap, cutting surface flatness, and dross amount), and cutting efficiency of different cutting media were comparatively analysed, and the research progress of flame cutting of continuous casting billet in iron and steel enterprises and scientific research institutes at domestic and international was summarized. On this basis, combined with the intelligent control hydrogen oxygen cutting technology developed by the author's team, pointed out the shortcomings of the current flame cutting and the future development trend are pointed out.
