04.06.2015 · Steel is made primarily in a two-step process. In the primary steelmaking step, liquid iron is converted into steel by the basic oxygen furnace (BOF) process, or by melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking is a refining process in which alloying metals are added and impurities are removed.
Iron and Steel Manufacturing
Iron and Steel Manufacturing Industry Description and Practices Steel is manufactured by the stone reduction of iron ore, using an integrated steel manufac-turing process or a direct reduction process. In the conventional integrated steel manufacturing process, the iron from the blast furnace is con-verted to steel in a basic oxygen furnace (BOF).
Steel Production - American Iron and Steel Institute
How Steel Is Made. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. …

12.5 Iron And Steel Production
The production of steel at an integrated iron and steel plant is accomplished using several interrelated processes. The major operations are: (1) coke production, (2) sinter production, (3) iron production, (4) iron preparation, (5) steel production, (6) semifinished product preparation, (7) finished
Chapter 73. Iron and Steel - ilocis.org
Blast furnaces, converters and coke ovens produce large quantities of gases in the process of iron and steel manufacturing. After the dust has been removed, these gases are used as fuel sources in the various plants, and some are supplied to stone plants for use as raw materials.
Steelmaking - Wikipedia
Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygenand entrained impurities (termed "inclusions") in the steel is also important to ensure the quality of the produ…

Steel manufacture - SteelConstruction.info
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 …
The Steel Making Industry - IDEALS
Steel production at an integrated steel plant involves three basic steps. Next the iron ore is melted in a furnace. Finally, the molten iron is processed to produce steel. one facility; however, the fuel source is often purchased from off-site producers.
Steel Manufacturing Process - Association for Iron …
The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel.
Iron Ore Processing for the Blast Furnace
Creating steel from low-grade iron ore requires a long process of mining, crushing, separating, concentrating, mixing, pelletizing, and shipping. The process of mining low -grade iron ore, or taconite, requires massive resources. Heavy industrial mining equipment, expansive mines, and a skilled labor pool are all required.
