Electrovortex motion of a melt in dc furnaces with a bottom electrode
Abstract
The effect of the Lorenz force on the origination of the electrovortex motion of a metal melt in dc electric steel furnaces with a bottom electrode is evaluated. The motion of a metal melt is described by equations of magnetic hydrodynamics for isothermal liquid, which are solved by the finite element method. The numerical solution is compared with theoretical results and experimental data of other authors. From analysis of the results obtained, conclusions are drawn that the Lorenz force has a marked effect on the origination of the vortex motion of a melt.
