PROBLEM TO BE SOLVED: To provide a nozzle for continuous casting which increases the affinity of an anti-oxidant to the inner hole face of a nozzle inner hole, and prevents the occurrence of the partial swelling, shrinkage, peeling or the like in the anti-oxidation film.SOLUTION: The nozzle 1 for continuous casting includes: a nozzle body 2; and a nozzle inner hole 3 formed through the inside of the nozzle body 2, and through which molten steel circulates. The inner hole face 3a of the nozzle inner hole 3 is provided with grooves 4 formed so as to be lattice shape in such a manner that they are crossed each other over ≥50% of the total area thereof. In this way, the partial swelling, shrinkage, peeling or the like of an anti-oxidation film can be suppressed. |
