Question

The temperature of the slag zone in the metallurgy of iron using blast furnace is:

• A. 1200-1500${}^{0}C$
• B. 1500-1600${}^{0}C$
• C. 800-1000${}^{0}C$
• D. more than 2000${}^{0}C$

Answer 1

Answer: (C)

800-1000${}^{0}C$

Slag is the fusible compound formed by the combination of flux and gangue.

$\underset{Flux}{CaO}+\underset{Gangue}{Si{O}_2}\to \underset{Slag}{CaSi{O}_3}$

At the temperature of the slag zone in the metallurgy of iron using blast furnace is ${800}^{o}C–{1000}^{o}C$.

Option (C) is correct.
