Abstract
A method of and an apparatus for the production of steel utilizing a single vessel for the electric arc smelting of scrap, directly reduced iron or pig iron in solid form, and for the oxygen blowing of the resulting melt through an oxygen lance introduced via a tower-shaped part of the roof. Another part of the roof can pivot to allow charging of the furnace with solids and the tower can be provided with a funnel enabling a molten iron charge to be fed to the furnace.
