Steelmaking slag (BOF and EAF) is cooled similarly to aircooled BF slag and is used for most of the same purposes. As the production process varies at this stage depending on the type of steel being made, the resulting slags also have diverse chemical properties making them more difficult to use than ironmaking slags.

Basic Oxygen Furnace Steelmaking - Steel Technology

The Basic Oxygen Steelmaking process differs from the EAF is that BOF is self-sufficient in energy. The primary raw materials for the BOP are 70-80% liquid hot metal from the blast furnace and the steel scrap need to be balanced. These are charged into the Basic Oxygen Furnace (BOF) vessel. Oxygen (>99.5% pure) is “blown” into the BOF at
