What is the process of obtaining pig iron from iron ore and how can it be converted into wrought iron, steel, and cast iron?
Understand the Problem
The question appears to be addressing the process of obtaining pig iron from iron ore and its subsequent conversion into wrought iron, steel, and cast iron. It provides details about how impurities are removed during the smelting process.
Answer
Pig iron is made in a blast furnace; converted to wrought iron by puddling, steel by refining, and cast iron by casting.
Pig iron is obtained from iron ore using a blast furnace where coke and iron ore react to form molten iron or pig iron. To convert it into other forms: Wrought iron is made by puddling; steel is made by refining and reducing carbon content; cast iron is remelted and cast into forms.

More Information
Pig iron, with high carbon content, is the first product from a blast furnace used as a raw material in steelmaking. Wrought iron is known for its malleability and toughness, while cast iron is hard and brittle due to higher carbon content.
Tips
Ensure precise temperature control during conversion to prevent undesirable characteristics in the final product.
