Pig iron Wikipedia

Pig iron is an intermediate product of the iron industry in the production of steel, also known as crude iron, which is obtained by smelting iron ore in a blast furnace. Pig iron has a very high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications. The traditional shape of the molds used for pig iron ingots was a branching structure formed in sand, wit

Creating Iron HowStuffWorks

At this point, the liquid iron typically flows through a channel and into a bed of sand. Once it cools, this metal is known as pig iron. To create a ton of pig iron, you start with 2 tons (1.8 metric tons) of ore, 1 ton of coke (0.9 metric tons) and a half ton (0.45 metric tons) of limestone. The fire consumes 5 tons (4.5 metric tons) of air.

I, Pig iron is made in a blast furnace by smelting iron ore with coke and limestone. A. In general it has around 95 percent FE content, plus certain impurities such as carbon (say, 4 percent), and silicon, manganese, phosphorous and sulfur.

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

17-09-2020· The name “pig iron” comes from the resemblance of the long channel to a mother pig, and the smaller channels to suckling piglets. In most modern pig iron production, however, this process is no longer used, as methods have been developed that allow the pig iron to be transported in a liquid state, rather than as a hard material.
