IMMERSION NOZZLE FOR CONTINUOUS CASTING

An immersion nozzle 10 for continuous casting which reduces the drift of molten steel flowing from the outlets 14 of the nozzle and reduces the level fluctuation at the molten steel surface and which is easy to manufacture. The immersion nozzle 10 includes: a tubular body 11 with a bottom 15, the tubular body 11 having an inlet 13 for entry of molten steel disposed at an upper end and a passage 12 extending inside the tubular body 11 downward from the inlet 13; and a pair of opposing outlets 14 disposed in a sidewall at a lower section of the tubular body 11 so as to communicate with the passage 12, the nozzle 10 characterized by a pair of opposing ridges 16 extending horizontally on an inner wall and projecting into the passage 12 from the inner wall 18 between the pair of outlets 14, the inner wall 18 defining the passage 12.
