Semifinished metal produced from iron ore in blast furnace, containing 92 percent iron, high amounts of carbon (typically up to percent), and balance largely manganese and silicone plus small amounts of phosphorus, sulfur, and other impurities. Pig iron is further refined in a furnace for conversion into steel.

Iron Furnace History in Ohio. The name pig iron is meaningless to nonfarm people, as it is a figment of the imagination of the blast furnace workersall of whom were very familiar with the keeping of pigs. Workers before World War I were, in almost all cases, required to have a kitchen garden, and keep cows, chickens and pigs.

Pig iron is produced from the blast furnace. The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.

In general, electric furnaces make higher grade NPI between eight and 15 percent nickel. This is already similar to the quality of ferronickel produced by nickel giants like Vale. In contrast, the nickel pig iron produced by blast furnaces contain only four to 13 percent nickel. Smelting and sintering processes remove the impurities.

Carbon Steels. Steelmaking practice for the production of carbon steels traditionally starts from pig iron produced from the blast furnace. The high carbon in the iron, in the region of 3–4%, is the result of the liquid iron percolating down through the coke in the furnace stack.
