Abstract：Ultra-low carbon steel has very low carbon content， so it is necessary to avoid carbon increasing of the liquid steel during the continuous casting process， and mold flux preparation should mainly consider the lubrication and consumption of the mold flux. Combined with the latest patent application for invention about the mold flux for continuous casting of ultra low carbon steel， the development situation of mold flux for continuous casting of ultra low carbon steel was analyzed. According to the research on the latest mold flux component， the mold flux of ultra low carbon steel mainly included carbon mold flux， no carbon color mold flux， boron content controlling mold flux， fluorine content controlling mold flux. The effects of these fluxes which could be achieved were discussed. Some basis for the future company in the selection and application of mold flux of ultra low carbon steel were provided.
