The blast furnace converts iron ore to pig iron; the steel furnaces convert the pig iron to steel; and the rolling mills shape the steel into sheets, slabs, or bars. Blast furnace. A blast furnace is a chimney-like structure in which iron ores (mainly FeO, Fe 2 O 3, and Fe 3 O 4 ) are converted into iron metal.
Iron-Ore Iron-ore are rocks and minerals that contain the metal iron (Iron Ore). Iron-ore is harvested in large-scales through various mining techniques (STEEL: From Start to Finish). The iron-ore is ground to a powder and then the ore is separated with strong magnets (STEEL: From Start to Finish). The ore is then heated and formed into marble ...
Iron ore is mined in many countries including Australia, Brazil, China, India, the United States, and more.

Apr 22, 2019· 6 IRON ORE COKE LIME STONE The basic materials used for the manufacture of pig iron (also called hot metal) are iron ore, coke, and limestone. The coke is burned as a fuel to heat the furnace; as it burns, the coke gives off carbon monoxide, which combines with the iron oxides in the ore, reducing them to metallic iron.
As iron is the main component of steel it firstly needs to be made. Iron ore, lime, and coke are placed into a blast furnace and melted. The resulting liquid known as molten iron is then formed. As molten iron still contains around 4% – 4.5% impurities such as carbon which in turn make the metal brittle, they need to be eradicated.
The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items.
A simplified diagram of a Blast Furnace is drawn below. A typical blast furnace may be up to 32 metres in height and 10 metres in diameter. They have thick steel sides, lined with refractory bricks, to ensure that heat is not lost. Blast furnaces are used continuously and …
This process made steel production cheaper, efficient and easier. Steel is made by putting iron through a process known as smelting, where iron is extracted from the iron ore and excess oxygen is removed and the iron is combined with chemical partners such as carbon. Steel, compared to pure iron is more rust resistant and has a better weldability.
Mar 07, 2016· While the common inputs for BOF steelmaking are iron ore and coal, the EAF furnace operates using scrap steel – steel already produced and ready to be recycled. Nucor, America's largest steel producer, has made its fortune by popularizing the EAF process at a time when scrap steel making became more effective than the BOF processes of the ...
Blast furnace-basic oxygen furnace uses iron ore as its base raw material that accounts over just 50% of BOF steel costs, and electric arc furnace uses scrap as its base that represents around 75% of EAF steel cost. The Basic Oxygen Steelmaking process differs …
Mar 20, 2017· In his discussion of electric-furnace production of pig iron and pig steel before the Engineers' Society of Western Pennsylvania, Dr. J. W. Richards defines pig steel as "a metal with 2.2 per cent, or less of carbon, a very small amount of silicon and manganese, low in sulphur and phosphorus, and made directly from iron ore in the electric ...

Aug 21, 2020· Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten iron—also referred to as hot metal—still contains 4-4.5% carbon and other impurities that make it brittle.
Jun 21, 2018· The flow chart shows the basic steps of how iron ore is used to produce semi-finished products of steel. The individual process steps are explained in more detail in the following articles. Figure: From iron ore to steel (flow chart) Steel is extracted from iron ores (mainly found in sedimentary rocks) and is also known as ore smelting.
Nov 01, 2017· Once the pig iron ore has been produced it is sent to an basic oxygen furnace, or BOF, to turn it into steel. Molten iron from a blast furnace is "charged" …
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. The electric arc furnace melts recycled steel ...

To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. In fact, a very simple definition of steel is "iron alloyed with carbon, usually less than 1%." The following text is taken from the Structural Manual For Ironworkers Manual V-Volume I.
