This slag is a byproduct from steelmaking processes in which the components of pig iron and steel-scrap are modified in order to produce steel that is so highly valued for excellent toughness and workability.
1. Introduction. Steel slag is the oxidized material that is generated when lime, dolomite, and other auxiliary materials are added, and oxygen is blown onto the pig iron produced by a blast furnace to remove carbon (C), phosphorus (P), sulfur (S), and other components to produce crude steel in a basic oxygen furnace (BOF).
