Iron and steel production

History of ferrous metallurgy

Iron production
(Ironworks)

Smelting	Bloomery (produces sponge iron) Blast furnace (Cold blast • Hot blast) (produces pig iron)
Secondary	Wrought iron (via Finery forge or Puddling furnace) Cast iron (via Cupola furnace or Induction furnace)

Steelmaking
(Steel mill)

Primary (Pre-1850)	Pattern welding (Damascus steel) Crucible steel Tatara furnace Cementation process
Primary (Post-1850)	Bessemer process Open hearth furnace Electric arc furnace Basic oxygen process HIsarna process
Secondary	Electro-slag remelting Vacuum arc remelting Argon oxygen decarburization
