Question

Sort the processes involved in steel production in chronological order (top to bottom).

• A. Forging
• B. Casting
• C. Pressing
• D. Rolling

Answer 1

In order to obtain steel from pig iron, it needs to go through further refining. Pig iron is again melted, while the impurities are removed through oxidation. Manganese, nickel, and chromium are then added to improve the steel’s properties. Finally, the steel produced through these processes is shaped through rolling, pressing, casting, and forging.
