Abstract
In the process for making steel from scrap, in each converter cycle following the charging of scrap, an amount of hot metal charge originating from a preceding converter cycle is charged over the scrap. The total charge is melted down through the introduction of fuel and oxygen via sub bath or submerged inlet tuyeres. The molten tap is tapped either into two storage vessels, in repetition cycles, and used as a hot metal charge during two subsequent charges, or the tap is added for subsequent processing, in production cycles, particularly for a casting operation wherein finish-refining is effected prior to the tapping.
