The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag. This is the major source of steel slag aggregate. After being tapped from the furnace, the molten steel is transferred in a ladle for further refining to remove additional impurities still contained within the steel.
Steel slag is a byproduct of the steelmaking and steel refining processes. This paper provides an overview of the different types of steel slag that are generated from basicoxygenfurnace (BOF) steelmaking, electricarcfurnace (EAF) steelmaking, and ladlefurnace steel refining processes. The mineralogical and morphological properties of BOF and electricarcfurnaceladle [EAF(L)] slag ...
stainless steel: see steel steel, alloy of iron, carbon, and small proportions of other elements. Iron contains impurities in the form of silicon, phosphorus, sulfur, and manganese; steelmaking involves the removal of these impurities, known as slag, and the addition of desirable alloying elements.
