Sažetak

At 950 mm × 230 mm slab crystallizer as the prototype, the flow field distribution inside the mold under different conditions was calculated using FLUENT simulation software, and the effects of different casting speeds and nozzle immersion depths on the flow field inside the mold were analyzed. The results show that an increase in casting speed intensifies the fluctuation of the steel slag interface, and as the immersion depth of the nozzle increases, the fluctuation of the steel slag interface gradually stabilizes. Section 950 mm × 230 mm crystallizer with a submerged depth of 120 mm at the nozzle and a casting speed of 1,1 m/min can avoid slag entrapment.
