The process of making pig iron from iron ore

Mar 20, 2017 At any place where there is a market demand for steel, and pig iron can be made in the electric furnace at a profit, the steel ultimately produced would be cheaper, if made by the electric reduction of iron ore to pig steel, followed by refining in another furnace if necessary, than if the product of the electric-reduction furnace was pig iron to be subsequently converted to steel in another furnace

    Using water-powered bellows, a large and consistent volume of air created enough heat to completely melt the ore from which iron was made. The technology created two major developments in iron production. First, blast furnaces were now able to make cast iron for the production of hollowware such as pots and kettles

    Pig iron is the basic building block of all ferrous metals. It is formed when iron ore is refined in a furnace in the presence of charcoal, limestone and air. It is the basic form of iron used to make decorative wrought iron items. When the pig iron is further refined and a minimum amount of carbon is added, the crystalline structure of the metal changes and steel is produced

    Introduction. Iron making evolved over a few thousand years. Using the ancient bloomery method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the direct process. By the 1100s water-powered hammers replaced
