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…

Modern methods, however, are still based on the same premise as the original Bessemer Process, which uses oxygen to lower the carbon content in iron. Today, steel production makes use of recycled materials as well as traditional raw materials, such as iron ore, coal, and limestone.

Iron ore - Wikipedia
This stockpile of iron ore pellets will be used in steel production. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe

Process for Manufacturing of Iron Carbide – IspatGuru. It reduces iron ore to iron carbide in a fluidized bed reactor, by contacting the iron ore with process gas consisting primarily of methane (CH4) and hydrogen (H2) The process for the manufacturing iron carbide was originally designed and developed at Hazen Research Inc in Golden, Colorado, USA by the technical vice president Dr Frank M ...
The Making of Iron & Steel - SEAISI
Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.
Pig Iron Manufacturing Process
In this stone the writer does not advocate the production of pig steel from ore in the electric furnace as a competitor of the present method of steel production with pig iron as an intermediate step, but presents the general metallurgical side of such a process and its economical possibilities in regions where power is cheap, and fuel and reducing materials are expensive, as, for example ...

Steel manufacture - SteelConstruction.info
Iron and steel making by-products. As with all large-scale manufacturing processes, the production or iron and steel generates by-products. On average the production of 1 tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of by-products. The main by-products produced during iron and crude steel production are slags (90%), dusts and sludges.
