Steelmaking - Wikipedia

Modern steelmaking processes can be divided into two categories: primary and secondary. Primary steelmaking involves converting liquid iron from a blast furnace and steel scrap into steel via basic oxygen steelmaking, or melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking involves refining of the crude steel before casting and the various operations are normally carried out in ladles. In secondary metallurgy, alloying agents are added, dissolved gases in th

Steel making process – ArcelorMittal

Steel is produced from iron ore or scrap. Iron ore is a mineral aggregate that can be converted economically into iron. The quality of the iron ore is mainly determined by its composition; a high iron content and low sulphur and phosphorus contents are favorable. Iron ore can be found all over the world, but its iron content varies.

Manufacture of Steel - Steel Manufacturing Process and Steps

Jun 06, 2017 · The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace. Temperature raised to 1600oF. This high temp causes the coke to burn and melt the iron. This red hot iron drained at an opening at the base of the furnace.
