ABSTRACT:
In a method of producing successive heats of refined steel wherein successive charges of molten, impure iron are refined by oxygen in the presence of at least one flux to form molten, refined steel and liquid slag, followed by the separation of said molten, refined steel and liquid slag, the improvement wherein a liquid slag from one of said refining operations is brought into contact with and caused to react with a batch of molten, impure iron which comprises a charge for a subsequent refining operation other than the immediate next successive refining operation to that from which the said liquid slag was obtained, such that at least some of the free and combined iron contained in said slag is substantially reduced and dissolved into said molten, impure iron, and such that the molten, impure iron is at least partially refined.
