The BF process occurs in a counterflow of descending charge materials and ascending gases. Heat exchange between the ...
Iron processing
Hot metal (blast-furnace iron)Most blast furnaces are linked to a basic oxygen steel plant, for which the hot metal typically contains 4 to 4.5 percent carbon, 0.6 to 0.8 percent silicon, 0.03 percent sulfur, 0.7 to 0.8 percent manganese, and 0.15 percent phosphorus.Tapping temperatures are in the range 1,400° to 1,500° C (2,550° to 2,700° F); to save energy, the hot …
Iron Extraction by Blast Furnace Metallurgy
Iron extraction by blast furnace metallurgy is an extremely important concept which shows what happens after the iron has been extracted from iron ore in a blast furnace. This whole process is a reduction reaction where oxygen is removed from the iron (III) oxide to leave behind iron. This process of metallurgy is taught in-depth in chapter 6 ...
23.3: Metallurgy of Iron and Steel
Originally, the iron was collected in pools called pigs, which is the origin of the name pig iron. Figure (PageIndex{1}): A Blast Furnace for Converting Iron Oxides to Iron Metal. (a) The furnace is charged with …
Extraction of Iron | Metallurgy | Blast Furnace and …
A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.
Blast Furnace Ironmaking
Blast furnace uses iron ore as the iron-bearing raw materials, and coke and pulverized coal as reducing agents and heat source, lime, or limestone as the fluxing agents. …

Figure 1: Steelmaking byproducts for blast furnace (BF), basic oxygen furnace (BOF) and electric arc furnace (EAF) processes. Source: World Steel Association (worldsteel) The first step in the production of steel or cast iron alloys is the reduction of iron ore—which contains iron oxide and gangue or mineral impurities—to unrefined, reduced iron form.
Making iron & steel
Before iron ore can be used, oxygen must be removed from it. Known as 'reducing', this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace process also produces two ...
