| Abstract Scope |
Bloom continuous casting is widely used in steel production. The flow state and liquid level fluctuation of molten steel inside the bloom continuous casting mold directly affect the quality of the bloom. This article conducts numerical simulation on different submerged depths and side hole inclination angles of the submerged nozzle during the bloom continuous casting process and the F index is used to judge the liquid level fluctuation during the casting process. The results show that the optimal nozzle parameter combinations are 100 mm submerged depth with 15°port angle and 110 mm submerged depth with 15°port angle when the casting speed is 0.55 m/min. The flow field of the molten steel in the mold is reasonable and the narrow surfaces are less impacted. Also, the fluctuation of the liquid level is appropriate. This method can be emulated to optimize the mold parameters in most steel production processes. In addition, as the chamfer decreases, the heat flux at the corners continues to increase. |
