Mixing Behavior

Flow patterns and mixing behaviors in a gas stirred steelmaking ladle with a slag layer were discussed using a water model experiment as well as a numerical simulation. While the water model experiment was performed to investigate the effect of slag on the mixing behavior in ladle, the numerical simulation was carried out to figure out the flow pattern in ladle with a slag layer. Slag viscosity and its thickness in ladle were considered as major variables. It was found that a slag layer made a great change in the flow pattern in ladle, which, in turn, affected on the mixing behavior in ladle. A flow pattern without a slag layer showed that rising bubbles eventually made a recirculation loop at the central area of the ladle and this flow pattern was regarded as a favorable flow pattern for the better mixing behavior. However, a flow pattern with a slag layer showed distorted and localized recirculating loop near side wall below slag layer. This eventually gave a longer mixing time in ladle with a slag layer. Moreover, as the gas flow rate increases, slag existing on top of the ladle was found to be entrained into the melt. Slag viscosity and its thickness were found to be major variables affecting the behavior of slag entrainment. Lower the slag viscosity and thicker the slag layer, much more slag on top of the melt was entrained into the melt.

Based on the slab caster mold of ChengGang Company as prototype, the water model with 1:1 scale was used to study the effects of casting speed、nozzle port angle、immersion depth、bottom structure、mold width and other parameters on the surface flow velocity of liquid steel in slab caster mold. The results show that the effect of casting speed is biggest and with increase in the casting speed, the surface flow velocity of liquid steel is prominently increased, when the mold width at 1650mm, the surface flow velocity from 0.04m/s to 0.1m/s with the casting speed from 0.7m/min increased to 1.4m/min
