Theprocessstarts in the center of the wheel with the three main ingredients ofironin the form ofiron ore, coke and lime, which are fed into a blast furnace to producemolten iron. Themolten ironis mixed with recycledsteel scrapand furtherprocessedin a basic oxygen furnace to makesteel.
Steelis made primarily in a two-stepprocess. In the primarysteelmakingstep, liquidironis converted intosteelby the basic oxygen furnace (BOF)process, or bymelting scrap steelor direct reducediron(DRI) in an electric arc furnace. Secondarysteelmakingis arefining processin which alloying metals are added and impurities are removed.
Thesmeltingandrefining processforiron and steelin the BF-BOFprocessinvolves the carbon reduction ofiron ore(Fe 2 O 3) in the BF to makemolten iron, and decarburization ofmolten ironin the BOF to makemolten steel. Major reducing agent in the BF is the carbon monoxide gas (CO) generated by the oxidation of the carbon (C) in coke.
Jan 14, 2020· Today,steel productionmakes use of recycled materials as well as traditional raw materials, such asiron ore, coal, and limestone. Twoprocesses, basicoxygen steelmaking(BOS) and electric arc furnaces (EAF), account for virtually allsteel production.
Iron and steel manufacturing processes include cokemaking, sintering, briquetting,ironmaking(including direct-reducedironmaking), steelmaking,vacuum degassing,ladle metallurgy, casting, hot forming, forging, and finishing (e.g.,acid pickling,descaling, cold forming,surface cleaning,hot coating…

When combined with carbon,ironchanges character completely and becomes the alloysteel. Encyclopædia Britannica, Inc.Iron processing, use of a smeltingprocessto turn the ore into a form from which ...
This document deals only with integratediron and steel manufacturing; that on MiniSteelMills addresses the electric arcsteel process and steelfinishing processes.Steel manufacturingand finishing processes discussed in that document are also employed in integratedsteel plants.

Steelis simply low-carboniron. As such, thesteel manufacturing processbegins by smeltingironore (Fe 2 O 3 or Fe 3 O 4) in a blast furnace. This smeltingprocessmelts out and separatesironfrom the original rock material.Ironore is mixed with coke, a form of very pure coal.
Ironore is converted into various types ofironthrough several processes. The most commonprocessis the use of a blast furnace to produce pigironwhich is about 92-94%ironand 3-5% carbon with smaller amounts of other elements. Pigironhas only limited uses, and most of thisirongoes on to asteelmill where it is converted into ...
