Most steelmaking shops typically use about 20 to 35% of their total metallic charge as scrap, with the exact amount depending on the capacity of the steelmaking process. Much of this capacity depends on factors like the silicon, carbon and temperature of the hot metal, use of a post combustion lance, and external fuels charged, such as ...

The converter vanadium slag is a byproduct of the iron making process when using the vanadium titanomagnetite as the iron raw material. A cleaner process including calcified roasting, dilute acid leaching, precipitation purification, vanadium precipitation with ammonium salt followed by pyrogenic decomposition was proposed to extract vanadium resource from this slag.

The main objective of blast furnace ironmaking is to produce hot metal with consistent quality for BOF steelmaking process. Typically the specification of steel works requires a hot metal with 0.3–0.7% Si, 0.2–0.4% Mn, and 0.06–0.13% P, and a temperature as high as possible (1480–1520 °C at the tapping).
Modeling of Steelmaking Processes meets that ever-present demand and provides a solid knowledge base on which to build. With content designed to serve professionals and students, this book starts with an overview of steelmaking and develops into a focused description of underlying scientific fundamentals and applications.
