History

Which outcome occurs when iron production introduced coke fuel into blast furnaces during the Industrial Revolution?

A)Increased steel strength due to carbon absorption
B)Higher smelting temperatures enabled cast iron production
C)Reduced slag formation improved ore separation
D)Decreased carbon monoxide production improved worker safety

💡 Explanation

When coke replaced charcoal, a higher and more consistent heat was achieved because coke had a higher carbon content and greater structural integrity, enabling efficient combustion and carbon monoxide generation that extracted iron from its ore. Therefore, molten cast iron production increased, rather than increased steel strength, reduced slag, or decreased CO which require different metallurgical process conditions.
