Question:
High alumina content in the blast furnace slag ____ .
High alumina content in the blast furnace slag ____ .
Show Hint
The viscosity of slag affects the ease of its removal and the overall efficiency of the blast furnace operation.
Updated On: May 5, 2025
- Increases its melting point, but decreases its viscosity
- Does not affect its melting point but increases its viscosity
- Decreases both its melting point but increases its viscosity
- Increases both its melting point and viscosity
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
High alumina content in blast furnace slag increases both the melting point and viscosity, which helps in trapping impurities but can make the slag more difficult to handle.
