摘要：
The stirring ability and flow field characteristic of conventional and nozzle twisted oxygen lance (Twisted angles are 4 degrees, 8 degrees and 12 degrees, respectively) on the molten bath were analysed. The mixing time, impacting depth and impacting radius are measured. Flow field characteristics of multiphase flow are calculated by numerical simulation. Compared with conventional oxygen lance at industrial application research, it shows that the 8 degrees oxygen lance could stir molten better in steelmaking process for the 120t dephosphorisation converter. These findings agree well with the experimental results of the water experiments and the numerical simulations. Finally, an optimal twisted angle is determined.
