Scrap Is Used In Blast Furnaces

Steel Scrap an overview ScienceDirect Topics. 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].

Scrap use in the steel industry

2021-9-3  In blast furnace (BF) steelmaking, each charge of the basic oxygen furnace, in which carbon carbon-rich pig iron is refined into crude steel, typically contains 15%-25% scrap. Scrap acts as a cooling agent, absorbing excess heat from the exothermic decarbonisation process, and also as a source of iron units. In some cases, scrap is added directly
