Abstract
The angular thermal radiation coefficients and the efficiency of arcs for different distances from them to the walls of electric-arc furnaces of 0.5 to 120 t capacity are calculated. A relationship between the arc efficiency and the specific power consumption of the furnaces is established. The arc efficiency versus the depth of submersion of the arcs into the metal bath and slag in high- and low-capacity electric-arc furnaces is calculated and plotted.
