  • Steelmaking Wikipedia

    Steelmaking has played a crucial role in the development of ancient, medieval, and modern technological societies. Early processes of steel making were made during the classical era in Ancient Iran, Ancient China, India, and Rome but the process of ancient steelmaking was lost in the West after the fall of the Western Roman Empire in the 5th

  • Basic oxygen steelmaking Wikipedia

    The basic oxygen steel-making process is as follows: Molten pig iron (sometimes referred to as "hot metal") from a blast furnace is poured into a large refractory-lined container called a ladle. The metal in the ladle is sent directly for basic oxygen steelmaking or to a pretreatment stage.

  • Steel Wikipedia

    In these processes pig iron was refined (fined) in a finery forge to produce bar iron, which was then used in steel-making. The production of steel by the cementation process was described in a treatise published in Prague in 1574 and was in use in Nuremberg from 1601.

  • Bessemer process Wikipedia

    The Bessemer process revolutionized steel manufacture by decreasing its cost, from £40 per long ton to £6–7 per long ton, along with greatly increasing the scale and speed of production of this vital raw material. The process also decreased the labor requirements for steel-making.

  • Steps in the Modern Steelmaking Process

    Methods for manufacturing steel have evolved significantly since industrial production began in the late 19th century. 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.

  • Steel Simple English Wikipedia, the free

    Cheap steel helped start the Industrial Revolution in England and in Europe. The first industrial Converter (metallurgy) for making cheap steel was the Bessemer converter, followed by Siemens-Martin open-hearth process. Today the most common way of making steel is the basic-oxygen process. The converter is a large turnip-shaped vessel.

  • Open hearth furnace Wikipedia

    Open hearth furnaces are one of a number of kinds of furnace where excess carbon and other impurities are burnt out of pig iron to produce steel. Since steel is difficult to manufacture due to its high melting point, normal fuels and furnaces were insufficient and the open hearth furnace was developed to overcome this difficulty.

  • Sand casting Wikipedia

    Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.

  • Iron Wikipedia

    Steel (with smaller carbon content than pig iron but more than wrought iron) was first produced in antiquity by using a bloomery. Blacksmiths in Luristan in western Persia were making good steel by 1000 BC. Then improved versions, Wootz steel by India and Damascus steel were developed around 300 BC and AD 500 respectively.

  • Die (manufacturing) Wikipedia

    Wire-making dies have a hole through the middle of them. A wire or rod of steel, copper, other metals, or alloy enters into one side and is lubricated and reduced in size. The leading tip of the wire is usually pointed in the process. The tip of the wire is then guided into the die and rolled onto a

  • The Roles of Coal and Coke in Steelmaking

    Another well-known process of steel making is completed with an electric arc furnace. Unlike a blast furnace, an electric arc furnace uses no iron in steel making. Coke and coal are not required during this process, as it uses electricity instead. Coke is often produced away from the steel mills, and is often delivered via railway.

  • Basic oxygen process metallurgy Britannica

    Basic oxygen process (BOP), a steelmaking method in which pure oxygen is blown into a bath of molten blast-furnace iron and scrap. The oxygen initiates a series of intensively exothermic (heat-releasing) reactions, including the oxidation of such impurities as carbon, silicon, phosphorus, and

  • Vacuum Degassing of Steel Vacaero

    In the steel smelting process, unwanted gases are dissolved in the liquid, which could produce any number of imperfections and defects. A common method used to remove these undesired gases is vacuum degassing. The process is done after the molten steel has left the furnace and before being poured into ingots or introduced into a continuous caster.
