How do you get wrought iron?

Views: 26 Update date: Nov 10,2023
Historical methods for producing wrought iron involved a process called puddling, which was commonly used until the late 19th century. Here's a general overview of the traditional process:

Iron Ore: The process begins with iron ore, typically in the form of hematite (Fe2O3) or magnetite (Fe3O4).

Smelting: Iron ore is smelted in a blast furnace to extract pig iron. Pig iron is a high-carbon, brittle material.

Puddling: The pig iron is then subjected to a process called puddling. Puddling involves melting the pig iron in a reverberatory furnace (a type of furnace with a shallow hearth and an arched roof). During puddling, the iron is stirred or "puddled" while being exposed to oxidizing gases. This process removes impurities like carbon and silicon, producing a more malleable and purer form of iron.

Wrought Iron Formation: The puddled iron is then gathered into balls and rolled or hammered to expel remaining slag and further refine the iron. This process also helps to distribute the carbon content more evenly.

Wrought Iron Product: The resulting product is wrought iron, which is a fibrous material with a grain resembling wood. Wrought iron is characterized by its low carbon content, making it more malleable and ductile compared to other forms of iron.
