Abstract (en)
[origin: EP3915696A1] It is intended to provide a flat immersion nozzle capable of stabilizing a molten steel discharge flow to stabilize an in-mold bath surface, i.e., reduce the fluctuation of the in-mold bath surface. Provided is an immersion nozzle having a flat portion whose inner bore has a thickness Tn and a width Wn greater than the thickness Tn, wherein two lateral protrusions 1 each protruding in a thickness direction are provided on each of opposed walls of the flat portion extending in a width direction. The lateral protrusions 1 are arranged at axial symmetrical positions with respect to a longitudinal central axis of the width-directionally extending walls, in pairs, such that each of them extends obliquely downwardly in the width direction, wherein two pairs of the lateral protrusions are arranged, respectively, on the opposed width-directionally extending walls, in opposed relation.
