PROBLEM TO BE SOLVED: To provide a mold powder having a little of entrapment of the powder while securing the in-flowing property, and a continuous casting method for producing a steel material excellent in the surface characteristic. SOLUTION: In the mold powder for using to the continuous casting method for steel, this mold powder has 10-150 poise viscosity at 1300°C, and the temperature becoming≥40% solid phase ratio at the solidifying time is 900-1200°C. Further, this mold powder has 10-150 poise the viscosity at 1300°C and ZrO<SB>2</SB>content therein is 3-15 mass% and C content is≤3 mass%. The method for continuously casting the steel, uses the powder while using an electromagnetic stirring and an electromagnetic brake in the mold. COPYRIGHT: (C)2004,JPO
