Question

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

1. 800-1000 ${}^{o}C$

2. 500-700 ${}^{o}C$

3. 1200-1500 ${}^{o}C$

Select the correct one from the given options.

Answer 1

1. 800-1000${}^0$ C

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

i.e., $CaO+SiO2⟶CaSi{O}_3$

Flux Gangue Slag

The temperature of the slag zone in the metallurgy of iron using blast furnace is ${800}^{0}C–{1000}^{0}C$.
