Study the role of Basicity and FeO content of slag on dephosphorisation of Steel using Induction furnace and FACTSAGE

摘要

Steels having low content of P are necessary for applications where high ductility is needed, such as thin sheets, deep drawn steel, and pipelines etc. In the earlier days, P control was not considered a big challenge in steel production since iron ores with low P contents were readily and cheaply available. However, in the recent past, because of high iron ore prices, lower priced iron ores from sources which normally have higher P content are being used and this has made P control an important activity during the steelmaking. Phosphorous in the steel mainly comes from iron ore, coke and recycled BOF Slag.
