<p>PROBLEM TO BE SOLVED: To provide a mold powder and a continuous casting method with which a cast slab having good cleanliness on the surface layer part thereof without generating the longitudinal crack can be obtained. SOLUTION: In the mold powder containing CaO, Si02, Al2O3 and fluorine compound as the basis components, the ratio in mass% of CaO/SiO2 is 1.1-1.5, and 5-15 mass% Al2O3, <=5 mass% of the total of content converted into the oxide of alkaline metals, <=1 mass% ZrO2, 0-8 mass% TiO2 and 4-12 mass% F, are contained, and the viscosity at 1300 deg.C is 2-6 Poise and the solidified point is >=1100 deg.C.</p> |
