Submersed nozzle for continuous bloom casting mold

The utility model relates to a submersed nozzle for a continuous bloom casting mold. The submersed nozzle comprises sidewalls forming a nozzle body, a closed bottom connected to the sidewalls, a vertical inner cavity surrounded by the sidewalls and the bottom, and four side holes evenly distributed on the sidewalls and communicated with the inner cavity, wherein the top end of the inner cavity is opened; among the four side holes, the center lines of the two adjacent side holes are perpendicular to each other, and the two opposite side holes are completely the same in size and shape and are axisymmetric with each other along the center line of the inner cavity of the nozzle; the center lines of the four side holes are respectively coincident with the central symmetrical lines of the four wall surfaces of the mold. The submersed nozzle is characterized in that the wall surfaces on the periphery of the four side holes are all inclined from inside to outside and appear to be in an expanding trumpet shape; and on
