Abstract：By increasing basicity and contents of CaF2 and Li2O, the mold flux for medium carbon steel slab casting was optimized.The optimized flux was adopted in plant trial of increasing castingspeed.The results showed that optimized flux has higher crystallization temperature，lower viscosity and melting point.In plant trial，liquid optimized flux thickness increased by 2 mm approximately，slag consumption increased by 0.03 kg/m2.At a casting speed of 13 m/min，heattransfer intensity，stability and slab quality cast with traditional flux were almost the same as cast with optimized flux at a casting speed of 15 m/min.
