  • Continuous casting mold, continuous casting device, and continuous casting method
    Patent number: 11045867
    Abstract: A crack-free continuous casting mold configured so that occurrence of cracks at a casting billet can be reduced even in a case where a casting speed exceeds 500 mm/min. The continuous casting mold continuously casts a casting billet while cooling molten metal by a cooling device provided at a cooling casting mold. The cooling device includes multiple cooling nozzles configured to release coolant water to the casting billet pulled out of the cooling casting mold to cool the casting billet. Multiple ejection ports of the multiple cooling nozzles are arranged along an outer circumferential direction of a surface of the casting billet. Each ejection port has a short side and a long side, and is configured such that the long side is arranged along an axial direction of the casting billet.
