Effect of Turbulence Inhibitor Ribs on “Open Eye” Formation in a Slab Tundish
The turbulence inhibitor (TI) significantly influences the flow field in the tundish. Through physical and numerical simulations, this study investigated the effects of ribs at the TI bottom on open eye formation and molten steel flow behavior in the tundish. Industrial trials were subsequently conducted to validate an optimized installation strategy. The results show that the presence of ribs significantly altered the flow direction, increased the flow length, reduced the open eye area by 6.1% to 7.3%, and decreased the loss of acid-soluble aluminum in molten steel by 13.8 to 16.2 ppm. Furthermore, aligning the ribs parallel to the tundish longitudinal axis exhibited superior performance in suppressing open eye formation, accompanied by reduced burn-off of acid-soluble aluminum in molten steel compared to alternative configurations.
