Abstract: Based on the principle of mutual action of micro electric currents in DC arc column and dynamic balance of electromagnetic forces in an arc region caused by spatial current loading wires, mathematical models of numerical simulation are proposed for DC arc deflection, arc deflection control by multi-botton-electrodes and by inclination of top electrode. Computer simulations are performed to investigate the deflection phenomenon and its control.

Key words: DC arc furnace, arc deflection, computer simulation, mathematical model
