The Effect of Pitch Circle Diameter of Electrodes on Current Distributions in Submerged Arc Furnace

摘要

This work presents computations of electric current distributions inside an industrial submerged arc furnace. A 3D model has been developed in ANSYS Fluent that solves Maxwell's equations based on scalar and vector potential approach that are treated as transport equations. In this paper, the approach is described in detail and numerical simulations are performed on an industrial three-phase submerged arc furnace. The current distributions within electrodes due to a change in pitch circle diameter of electrodes are presented. The results show that proximity effect decreases as the electrodes apart further.
