Cast iron begins its life as pig iron, which is remelted and often combined with large amounts of scrap iron and sometimes with steel. Contaminants are removed from the melted pig iron, and the iron, once melted, is then cast. Casting is the process of pouring the iron into a mold thus giving it a shape.

Pig iron is obtained by smelting (chemical reduction) of iron ore in the blast furnace. The basic materials used for the manufacture of pig iron 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 ...

Direct reduced iron Wikipedia. Directreduced iron has about the same iron content as pig iron, typically 90–94% total iron (depending on the quality of the raw ore) so it is an excellent feedstock for the electric furnaces used by mini mills, allowing them to use lower grades of scrap for the rest of the charge or to produce higher grades of steel.

In 1875, Britain accounted for 47% of world production of pig iron and almost 40% of steel. Forty percent of British output was exported to the, which was rapidly building its rail and industrial infrastructure. The growth of pig iron output was dramatic. Britain went from million tons in 1840 to million in 1870 and in 1913.

The pig iron can be further refined to produce steel or wrought iron. Both these methods reduce the carbon content of the pig iron, which in turn reduces the brittleness property of the metals. Wrought Iron Process. Wrought iron is produced by pummeling the pig iron using mechanically driven hammers in a wrought iron works.
