Abstract:
An object of the invention is to provide a casting nozzle in which attachment and deposition of alumina or the like can be prevented while a drift of molten steel can be prevented.The casting nozzle according to the invention is characterized in that the casting nozzle has a molten steel flow hole portion in which “a plurality of independent protrusion portions and/or concave portions” are disposed so that each of the protrusion portions and/or concave portions has a size satisfying the expression (1): H≧2 mm and the expression (2): L>2×H mm [in which “H” shows the maximum height of the protrusion portion or the maximum depth of the concave portion, and “L” shows the maximum length of a base portion of the protrusion portion or concave portion].
