Comparative Study of AC and DC Solvers Based on Current and Power Distributions in a Submerged Arc Furnace

This work discusses 3D models of current distribution in a three-phase submerged arc furnace that contains several components, such as electrodes, central arcs, craters, crater walls, and side arcs that connect electrodes and crater walls. A complete modeling approach requires time-dependent modeling of the AC electromagnetic fields and current distribution, while an approximation using a static DC approach enables a significant reduction in...
