Blast furnace Wikipedia

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with

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].

Basic oxygen steelmaking Wikipedia

Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel.Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.The process is known as basic because fluxes of burnt lime or
