Question:
The product of a commercial direct reduction process is
The product of a commercial direct reduction process is
Show Hint
Direct Reduction = Sponge Iron. It is called "sponge" because it is a solid with many internal pores.
Updated On: Jul 4, 2026
- Sponge iron
- Pig iron
- Liquid steel
- Hot steel
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept Direct Reduction (DR) refers to the solid-state reduction of iron ore to metallic iron using reducing gases or coal.
Step 2: Meaning Unlike the blast furnace, the DR process operates below the melting point of iron.
Step 3: Analysis Pig iron is the liquid product of a blast furnace. Liquid steel is the result of refining. Direct reduction produces a solid, porous metallic product.
Step 4: Conclusion This solid, porous product is commercially known as Sponge Iron or Direct Reduced Iron (DRI). Final Answer: (A)
