Optimization of Melted Iron Flow Behavior in Torpedo With Gas Blowing at Bottom
According to the practical physical dimension and processing parameters of a factory, AutoCAD software was used, a physical model was established. After completing mesh structure, Eulerian multiphase model was applied and adopting porous media model for the gas flow through the porous refractory, The flow field and mixing time of melted iron in torpedo with top and bottom blowing were computed using mathematical simulation approach, the effect of different gas blowing positions was studied. the results show that: Compared with the flow behavior of melted iron in torpedo without bottom blowing, the bottom blowing improve flow field of melted iron in torpedo, shorten mixing time, and increase desulphurizing efficiency. When porous refractories were located at the bottom of torpedo, which were 2650mm from gun centre, the flow field of melted iron in torpedo is better, mixing time is only 252s, that below half of origin torpedo’s.
