ABSTRACT:
A method for reducing iron oxide in a melt of iron by maintaining a reduction layer on the surface of the molten iron and passing the molten metal from the melt through vertical channels which communicate at the bottom of the metal melt an with a space at the top of the melt which is above that of the reduction layer so as to pass the melt including the oxide there through the reduction layer, the molten metal being lifted up through the channel by means of a gas lift pump action and heating the molten metal by inductive heating while it is flowing through the channel.
