Zhu Miaoyong; Zhou Haibin; Chen Zhaoping; Huang Zongze. BEHAVIORS OF JET AND FLUID FLOW IN AOD CONVERTER FOR STAINLESS STEEL REFINING. Acta Metall Sin, 2006, 42(6): 653-656 .
Abstract In AOD (argon and oxygen decarburization) converter, an important reactor for
stainless steelmaking, the flow has a great effect on the refining
process. Based on analysis of the behavior
of a gas jet injected horizontally into liquid from side wall, a
mathematical model was developed to predict the 3D turbulent
flow in AOD, and the effects of gas flow rate and arrangement of lances
on flow were investigated. The results show that the gas flow rate has
a great effect on the trajectory of jet and flow of molten steel in the
furnace, and the flow field and the distribution of turbulent kinetic
energy become more reasonable in the bath with multi-lance injection.
The predicted results were compared with the observation in water model,
which showed a good agreement.
