    1845 Iron ore discovered in Michigan by Marje-Gesick, an Ojibway chief Sault Ste Marie canal opens Lake Superior to ships from lower lakes 1855 Bessemer process revolutionizes steelmaking, making inexpensive steel available to waiting markets 1884 First shipment of iron ore ,...

  • Steel manufacture

    The generals reported that the cast-iron cannons of the time were not strong enough to deal with the forces of the more powerful shell so Bessemer developed his improved iron smelting process that produced large quantities of superior quality steel Modern steel is still made using technology based on Bessemer's process Modern iron making...

  • Steelmaking

    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 ....

  • Blast furnace

    A blast furnace is a special type of furnace for smelting iron from oreBlast furnaces are very large They can be up to 60 metres (200 ft) tall and 15 metres (49 ft) in diameterThe blast furnace is the biggest chemical reactorBlast furnaces are also called high ovens A blast furnace is usually built with a steel case and bricks made of magnesium oxide or other refractory material inside ....

    Liberating the iron mineral requires that the crude ore be ground to the consistency of face powder This process begins in the same way for both magnetite (metallic gray, below) and hematite (red-brown, below) as crude ore and water are fed into large primary autogenous mills...

  • Open hearth furnace

    The open hearth steelmaking had superseded the Bessemer process in UK by 1900, but elsewhere in Europe, especially in Germany, the Bessemer and Thomas processes were used until the late 1960s when they were superseded by basic oxygen steelmaking The last open-hearth furnace in the former East Germany was stopped in 1993 In the US, steel ....

  • The bessemer process and modern steel manufacturing

    As a result, only phosphorous-free iron ores from Wales and Sweden could be used for the process In 1876, Sidney Gilchrist Thomas, a Welshman, found an answer by adding a chemically basic flux- limestone- to the Bessemer Process This discovery, meant that, finally, iron ore from anywhere around the world could be used to make steel...

  • Ferrous metallurgy

    Ferrous metallurgy is the metallurgy of iron and its alloysIt began far back in prehistoryThe earliest surviving iron artifacts, from the 4th millennium BC in Egypt, were made from meteoritic iron-nickel It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores from Sub-Saharan Africa to China...

  • Different Types of Iron Ore

    Hematite is the most important iron ore The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron-content...

  • Bessemer process

    The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnaceThe key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron The oxidation also raises the temperature of the iron mass and keeps it molten...
