Process which makes steel more affordable and profitable

Process which makes steel more affordable and profitable

• A. Puddling
• B. Open-Hearth
• C. Bessemer
• D. Basic Oxygen

Answer: (C)

The key idea is that turning large amounts of iron into steel cheaply hinges on a fast, effective way to remove carbon and other impurities from molten iron. The Bessemer process achieves this by blowing air through molten pig iron, oxidizing excess carbon and impurities and dropping the steel’s carbon content to the desired level in a matter of minutes. This rapid, continuous method allowed steel to be produced in huge quantities at much lower cost, making it affordable for rails, buildings, ships, and machinery and boosting producer profits. Other methods like puddling and open-hearth were slower and more labor-intensive, while the basic oxygen process is a later refinement; the Bessemer breakthrough is the historic turning point that most clearly unlocked mass-produced, affordable steel.
