摘要
Iron ore is continuously converted to steel by introducing the ore into a shaft furnace of substantially equal cross-sectional width and thus forming a column of the charge therein; introducing a reducing gas into the furnace and exposing the bottom portion of the charge column from below to the heat of an electric arc the source of which is centrally disposed in the bottom of the furnace and thus causing the gradual super-heating and melting of the bottom portion of the charge so as to form a dome-shaped cavity at the bottom of the charge column while the column gradually moves downward under the force of gravity and collecting and tapping the formed molten steel at the bottom of the furnace.
