This article describes a new system of electric arc steelmaking based on use of oxygen with newly designed burner for increased productivity and reduced energy consumption. The need for the oxygen-fuel burner has been recognized for years. Because of the shape of the flux lines of the arc between electrodes, some areas receive much more heat than others and consequently melt faster, leaving portions of the furnace charge unmelted for some time. Until these cold areas are melted into the bath, the arcing process must continue in a less efficient mode, delaying the completion of the process and therefore reducing productivity and using more energy. Steelmakers have been looking for a heat source to apply to these cold areas so that all material would melt at the same time. The oxygen-fuel burner was chosen because of its ability to deliver a directed flame at temperatures nearing 5000/sup 0/F.
