PROBLEM TO BE SOLVED: To provide mold powder for continuous casting which can suppress surface cracks generated on a cast slab, without controlling surface temperature of the cast slab, and a continuous casting method.SOLUTION: The mold powder for continuous casting is added on a surface of molten steel at the time of continuous casting of steel. This mold powder for continuous casting includes SiO, LiO, AlO, CaO, and F as main components. The SiOcontent is 5.0 mass% or more to 20.0 mass% or less in concentration. The LiO content is 0.5 mass% or more to 5.0 mass% or less in concentration. The AlOcontent is 15.0 mass% or more to 30.0 mass% or less in concentration. Further, when it is defined that CaO (mass% in concentration) + F (mass% in concentration) ×(56/38) is T.CaO, a conditional expression of T.CaO/SiO≥2.0 is satisfied. |
