Abstract:
An electric arc furnace for continuous charging of ferrous materials and semicontinuous tapping of molten steel, comprising: (a) a body, having a central melting zone and at least two lateral shafts adjacent to said central melting zone, the base of said central melting zone being higher in elevation than the bases of said lateral shafts; (b) a roof over said body; (c) a central stack extending vertically from said roof above said central melting zone, said central stack having a means for charging ferrous materials into said central melting zone, having a means for removing exhaust gases from said central melting zone, and having a pivot point located below said means for charging; (d) a means for melting material charged into the furnace; (e) a means for tapping molten steel from the furnace; (f) a means for injecting refining aids into said lateral shafts; (g) at least one deslagging door positioned within said body; and (h) a means for tilting the furnace to alternatively tap said lateral shafts.
