摘　　要：在先进高强度钢连铸过程中,钢液中的Al会与传统CaO-SiO_2系保护渣发生渣钢反应导致保护渣性能恶化,从而影响连铸的顺行。因此,学者针对传统CaO-SiO_2系保护渣进行了设计和优化,并提出了以CaO-Al_2O_3系为基础的新型保护渣。系统地总结了反应型渣与非反应型渣的发展现状,为今后高强度钢连铸保护渣的设计和优化提供技术指导和研究方向。During the continuous casting of advanced high strength steels （AHSS） ,AI in molten steel will react with traditional CaO-SiO2-based mold flux and deteriorate mold flux properties, which influence the smooth operation of the continuous casting process. Therefore, researchers optimized the traditional CaO-SiO2-based mold flux and designed a new mold flux with CaO-AI2 03-based. This article systematic summarized the development of the traditional CaO-SiO2-based mold flux and the new Ca0-Al：O3-based mold flux, the purpose is to provide technical guidance and research direction for the design and optimization of continuous casting flux for high strength steel.
