Question

The form of iron obtained from blast furnace is:

• A. Steel
• B. Cast Iron
• C. Pig Iron
• D. Wrought Iron

Hint:

Pig iron is obtained from the blast furnace, and cast iron is refined from pig iron.

Answer 1

The Correct Option is B

Step 1: The form of iron obtained from the blast furnace is pig iron, which is then further refined to produce cast iron.
Step 2: Pig iron contains high amounts of carbon (3-4%) and impurities, while cast iron is obtained by refining pig iron and lowering its carbon content.
Step 3: Wrought iron is produced by further refining cast iron, removing most of the carbon and impurities.
