Magnetic suppression of arc blowout in a model arc furnace
Abstract
The two most likely causes of electromagnetic instability in electric furnace arcs are shown to be the kink and the fire-hose instabilities. Stabilization by an externally imposed axially magnetic field is analyzed, and experimental results are presented demonstrating stabilization of a small, pulsed test arc by this method.
