摘　　要：综述了国内外无氟连铸结晶器保护渣发展状况,分析了目前高碳钢和包晶钢(特别是亚包晶钢)用保护渣降氟过程中面临的主要问题:高温时粘度-温度特性的稳定性以及保护渣结晶性能的有效控制。在此基础上,提出了连铸无氟保护渣今后研究的方向和重点。Based on the summarization of current situation of fluorine-free mould fluxes at home and abroad, the main ;roblem during decreasing fluorine for high carbon steel and peritectic steel mould fluxes was analyzed, which includes the stability between viscosity and temperature at high temperature as well as effective control of crystallization properties. The further study and development trends of this field are also outlined.
