  • Description:
    A conventional electric arc furnace is provided with an outlet in a sidewall of the furnace, the inner and outer ends of which are positioned such that the outer end of the outlet is higher than the inner end of the outlet. The outer end of the outlet communicates directly with a graphite electrode having a hollow interior leading from the sidewall of the electric arc furnace to an electroslag furnace positioned below the electric arc furnace. After an initial charge of ore in the electric arc furnace is brought to the molten state with the slag floating on top of the molten metal, the level of molten metal is maintained above the inner end of the slanted outlet and caused to flow through the slanted outlet and hollow graphite electrode to the electroslag furnace. In the electroslag furnace, the molten metal solidifies on a movable base plate positioned at the bottom of the furnace that is slowly withdrawn out of the bottom of the electroslag furnace, thereby continuously forming the desired steel ingot.
