Steps in the Modern Steelmaking Process

Secondary steelmaking involves treating the molten steel produced from both BOS and EAF routes to adjust the steel composition. This is done by adding or removing certain elements and/or manipulating the temperature and production environment. Depending on the types of steel required, the following secondary steelmaking processes can be used:

Cyclic Use of Ladle Furnace Refining Slag for Desulfurization

The effect of sulfur enrichment on desulfurization reaction in ladle furnace slagrecycled process could be partially offset mainly by two aspects: the amount of slag increased with increases in the number of times recycled slag reused and in the quantity of lime added, which could directly reduce the mass fraction of sulfur in the recycled
