[0034] The metallurgical effect of the aerodynamic swirl tundish described in this patent is studied by using water model experiments and numerical simulations. The structure of the aerodynamic swirl tundish used for simulation research in the present invention is as follows Figure 1-3 As shown, the size parameters are as Figure 4-6 shown.
[0035] Among them, the length of the top of the tundish body 1 is L 1 =4180mm, width L 4 =1200mm, the bottom length of tundish body 1 is L 2 =3980mm, width L 3 =1000mm, height H of tundish body 1 1 =1000mm (the size shown is only the fluid area of the tundish, not including the refractory part); the inner diameter of the swirl chamber 2 of the external tundish Φ 1 =700mm, outer diameter Φ 2 =900mm, height H 2 =800mm (excluding the refractory part); the length of the groove or groove 3 between the tundish body 1 and the external tundish swirl chamber 2 is L=220mm, L'=240mm, width S=250mm, height H =200mm; Aperture diameter Φ of ...
