Arc monitoring on a 100 kVA experimental furnace
Abstract
A three phase arc furnace with inclined electrodes and gas injection through the electrodes was commissioned by the melting and smelting of a variety of materials. The furnace is equipped with extensive measuring and control instrumentation and facilities for data capture and analysis. The effects of different materials, rates of feeding, temperature, and gas injection on the arcing characteristics were studied. Simple and theory adequately describes some of the phenemona observed, and the spectral decomposition of the voltage waveform provides additional information. The application of these results to smelting processes is discussed.
