Based on tundish with length 8 m and liquid level 0.8 m for 3-strands H-beam bloom casting
the effect of curved dam flow-guiding hole diameter D(100~200 mm) and hole height H(350~550 mm) and angle between two flowguiding hole θ(20°~50°) on distribution of tundish liquid flow field and temperature field
liquid mixing status and removal of inclusions with different size has been simulated and studied by using three dimensional geometry model established with FLUENT soft ware. Results show that with flow-guiding hole diameter D 100 mm and height H 550 mm
and angle between two flow-guiding hole 0 50°
the comprehensive transfer performance in tundish is best
i. e. the difference of average residual time at each strand and the difference of temperature of liquid at each outlet are smaller and the removal rate of large size inclusions is up to 76%.
