613,819 ELECTRIC ARC FURNACE OPERATIONS Joseph J. Kociscin, 42 N. 22nd St, Kenilworth, NJ. 07033 Filed Feb. 3, 1967. Published Feb. 4, 1969 Class 75-12 1 Sheet Drawing. 9 Pages Specification PARTiCULATE PARTICULATE FEED Z2 3 PHASE A.C. SOURCE MOLTE N ME TAL A technique is described for preventing excessive erosion of the walls of an electric arc steelmaking furnace. The erosion is prevented by shielding the portion of the walls closest to the electrodes from the intense radiation created by the electric arcs. The shielding is provided by continuously adding powdered partially-reduced iron ore to the furnace between the walls of the furnace and the arcs.
