What is Steel mill?
[[File:Hoogovens.JPG|thumb|300px|Integrated steel mill in the Netherlands. The two massive towers are blast furnaces.]] A '''Steel mill''' or '''steelworks''' is an [[industry|industrial]] plant where [[steel]] is manufactured. Steel is an [[alloy]] of [[carbon]] and [[iron]]. Usually steel is produced in two stages: First, [[iron ore]] is [[Reduction (chemistry)|reduced]] (or [[Smelting|smelted]]) with [[Coke (fuel)|coke]] and [[limestone]]. This is done in a [[blast furnace]], and the result is [[pig iron]]. The part that is not used for pig iron is carried on as ''molten iron''. Impurities are removed, and [[alloying]] elements such as [[manganese]], [[nickel]], [[chromium]] and [[vanadium]] are added to produce the exact steel required. Steel mills then turn molten steel into blooms, ingots, slabs and sheet through [[Casting (metalworking)|casting]], [[hot rolling]] and [[cold rolling]]. {{stub}} [[Category:Industries]]
