Abstract Scope |
In this study, CFD is used to simulate an industrial scale submerged arc furnace (SAF) during tapping and production periods to realize the flow of metal and slag. The flow of the fluids through a porous coke bed is included, which creates a significant pressure loss and thus dominates the tapping flow rates. The aim of this study is to realize whether the metal or the slag being tapped is produced close to the tap-hole or in other parts of the furnace also, which informs us about the accumulation of the fluids in the furnace, thus affecting its efficiency. The first study focusses on flow of metal from different parts of the furnace for a non-porous bottom region (where metal is produced) and a porous top region (where slag is produced), and the second study focusses on flow of slag from different regions for uniform porosity in the furnace. |
