Melting pig iron in a cupola or induction furnace and oxidizing it produces which product?

• A. Cast iron
• B. Steel
• C. Wrought Iron
• D. Aluminum

Answer: (A)

Melting pig iron in a cupola or induction furnace and oxidizing it produces cast iron. Pig iron already has a high carbon content, and while oxidation removes some impurities, the carbon level remains high enough for the metal to be classified as cast iron. This makes it suitable for casting into shapes. Steel would need processes that lower carbon content, wrought iron requires near-very-low carbon, and aluminum is a different metal altogether.
