Mold powder for continuous casting of A1-containing sub-peritectic steel and continuous casting method

A mold powder for continuous casting of Al-containing hypo-peritectic steel, the Al-containing hypo-peritectic steel having Al:

• 0.2% to 2.0%, by mass %, and, in a hypo-peritectic region, C:
• 0.08% to 0.17%, by mass %, the mold powder comprising, by mass %:
• CaO;
• SiO2;
• Na2O:
• 8% or less;
• Li2O:
• 2% to 7%;
• F;
• and
• C:
• 2% to 10%,
• wherein Li2O/Na2O is 0.6 or more, where respective contents are by mass %,
• inequalities (1), (2), and (3) are satisfied:
• 1.01≤CaO/SiO2≤1.93 (1)
• 10<Li2O+0.5×Na2O+0.8×F<20 (2)
• 1.00≤F/(Li2O+0.5×Na2O+1.46)≤1.24 (3)
• CaO, SiO2, Li2O, Na2O, and F are respective contents of the elements by mass % in the mold powder
• a viscosity of the mold powder at 1,300° C. is in a range of 0.05 Pa·s to 0.20 Pa·s, and
• a crystallization temperature of the mold powder is in a range of 1,100° C. to 1,250° C.
