Abstract：Increment of the casting speed is an effective means to increase the efficiency of steelmaking production line. The continuous casting mold flux is an important technical link in the high casting speed technologies. Three kinds of low carbon steel high drawing speed mold flux (I, II, III) have been studied from the physical and chemical properties, use performance and use effect in industrial field. Through preliminary industrial tests, it was found that the thickness of the liquid slag layer of mold flux III is reasonable, high consumption, low friction, strong heat transfer capacity, high saturated heat flux, and low entrapped slag index of hot-rolled coils. Mold flux III was used for the high-speed conventional production of low-carbon steel slabs. More than 500 furnaces of low-carbon steel were casted at casting speed of 1.80-1.95 m/min. No adhesion alarm occurred, and the rate of entrapped slag was only 0.47%.
