Abstract
A process and an apparatus for removal of silicon, manganese, carbon and sulphur in a single reaction vessel from molten high carbon ferrous metal by conducting the highly reducing and highly oxidizing reactions at two different locations within the same reaction vessel. The removal of sulphur is effected at the bottom of the vessel, whereas the removal of manganese silicon and carbon is effected at the top layer of the molten layer of the molten metal where slag is present.
