Abstract

This article examines aspects of the propagation of heat flows in an arc furnace operated with different types of graphite electrodes: standard (solid) electrodes and electrodes with an axial opening. There are certain distinctive features to the formation of the electric arc at the end of the electrode when it contains such an opening. A model is constructed to calculate the heat flows in the system comprised of the arc, the bath, and the furnace’s working space. The data obtained from modeling show that charging pellets into the furnace through electrodes with axial openings makes it possible to intensify the steelmaking operation, increase the efficiency of the arcs, reduce oxidation-related losses of metal under the electrodes, and improve the energy-engineering indices of the production process.
