[0025] The following is combined with the examples and attachments Figure 1-4 The present invention is further explained, but the present invention is not limited.
[0026] Such as Figure 1 ~ Figure 4 As shown, an immersed nozzle for a shaped blank crystallizer includes a nozzle side wall 1, and the lower end of the nozzle side wall 1 is a closed bottom 2. The bottom 2 can be convex, flat or concave. The central channel of the side wall 1 of the nozzle is an inner cavity 3, and the shape of the inner cavity can be round, square or chamfered square. Located above the bottom 2 of the side wall 1 of the nozzle, there are two symmetrical first and second water holes 4, 5 and a third water hole 6. These three water holes are all connected to the inner cavity of the nozzle, and the upper and lower edges are in the horizontal direction. The included angle is -25°~15°. The first and second water holes 4 and 5 are equal in size, and the shape is a chamfered square with a chamfering ra...
