Results are presented from a numerical study of the hydrodynamic state of a metal bath in a 350-ton-capacity ladle during the injection of argon through bottom lances as part of the metal’s treatment on a ladle-furnace unit. A comparison is made between several variants of treatment, including the use of an injection unit with a single lance, two lances, and an asymmetric three-lance configuration. The hydrodynamics of the bath in the initial period of the injection operation are studied and an evaluation is made of melt flow velocity and the time it takes to establish steady-state flow. Trends in research being performed to develop efficient regimes for the injection of metal in ladles are also discussed.
