Pig iron - Wikipedia

Traditionally, pig iron was worked into wrought iron in finery forges, later puddling furnaces, and more recently, into steel. In these processes, pig iron is melted and a strong current of air is directed over it while it is stirred or agitated. This causes the dissolved impurities (such as silicon) to be thoroughly oxidized. An intermediate product of puddling is known as refined pig iron, finers metal, or refined iron. Pig iron can also be used to produce gray iron. This is achieved by remelting pig iron, often along with s

What Is Involved in Pig Iron Production? (with pictures)

2021-02-21  The process of pig iron production involves the combination of iron ore, charcoal, and an intermediary material known as a flux inside a blast furnace. As the materials combine with intense heat, much of the iron ore melts, creating a superheated, liquid form. Depending on the materials and cooling method used, pig iron production can be an intermediary step in the creation of

Basic oxygen steelmaking - Wikipedia

Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel. The process is known as basic because fluxes of burnt lime or dolomite, which are chemical bases, are added to promote the removal of impurities and protect the lining of the converter.

Pig Iron Production – Interstahl

Pig iron usually consists of about 92 percent iron, three to four percent carbon, and varying amounts of silicon (0.5 to 3%), manganese (0.5 to 6%), phosphorous (0.1 to 2%) and traces of sulfur (0.01 to 0.05 percent). Grey pig-iron is produced when the pig-iron is cooled slowly and the carbon settles out as graphite on the raw material. This type of carbon deposition needs specific amounts of ...
