Further, solid pig iron is used as "pure" raw material and carbon source in EAFs. The blast furnace–BOF route produces almost 66% total crude steel, and EAF route accounts for about 31%, while the blast furnace–open hearth process, which dominated steelmaking in the first half of the 1900s, had only a share of about 3% left [ 7 ].

What Is Involved in Pig Iron Production? (with pictures)

Jessica Ellis Iron ore is combined with charcoal in a blast furnace to create pig iron. The process of pig iron production involves the combination of iron ore, charcoal, and an intermediary material known as a flux inside a blast furnace.As the materials combine with intense heat, much of the iron ore melts, creating a superheated, liquid form.
