Inventor: KAITO MASAHIRO
IPC: B22D41/50
Filed: 2020-02-12
Abstract: To provide immersed nozzles 10, 10A which can stabilize a flow condition of molten steel in a mold and can effectively prevent mold powder entrainment.SOLUTION: Each of through holes 15 is composed of an internal through part 15a formed on a molten steel flow path 13 side, and an external through part 15b formed on a discharge port 16 side and communicating with the inside through part 15a. The internal through 15a reaches an outer periphery part 12b. An inner diameter of the external through part 15b is gradually expanded to the discharge port 16 from a communication part with the internal through part 15a. When jet streams of molten steel pass through the through holes and are discharged into the mold from the discharge port 16, they scatter along the external through part 15b expanding to the discharge port 16, so that flow rate of the jet streams discharged from the discharge port 16 is decelerated and is equalized as schematically shown by an arrow in Figure 4. Thus, it is possible to suppress stagnation occurring at an edge part on an opening end surface of the discharge port 16, stabilize a flow state of the molten steel in the mold, and prevent entrainment of mold powder into the molten steel.SELECTED DRAWING: Figure 2
