Q27 / 160 · AP EAMCET 2024 (21 May Shift 2) · Chemistry
The flux used in the preparation of wrought iron from cast iron in reverberatory furnace is
- A$\mathrm{SiO}_2$
- Correct answerB$\mathrm{CaCO}_3$
- CC
- DNaCN
Solution
$\mathrm{Fe}_2 \mathrm{O}_3+3 \dot{\mathrm{C}} \longrightarrow 2 \mathrm{Fe}+3 \mathrm{CO}$
Lime stone $\left(\mathrm{CaCO}_3\right)$ is added as a flux and sulphur, silicon and phosphorus are oxidixed and passed into the slag.
