Bessemer converter is used for

Options

A. steel
B. wrought iron
C. pig iron
D. cast iron

Answer

### Step-by-Step Solution:

1. **Understanding the Bessemer Converter**:
- The Bessemer converter is an important industrial process used for converting pig iron into steel.

2. **Process Overview**:
- The process involves blowing air through molten pig iron to oxidize impurities such as carbon, manganese, and silicon.

3. **Chemical Reactions**:
- During the conversion, several chemical reactions occur:
- **Oxidation of Manganese**:
\[ 2 \text{Mn} + \text{O}_2 \rightarrow 2 \text{MnO} \]
- **Oxidation of Silicon**:
\[ \text{Si} + \text{O}_2 \rightarrow \text{SiO}_2 \]
- **Oxidation of Carbon**:
\[ 2 \text{C} + \text{O}_2 \rightarrow 2 \text{CO} \]

4. **Formation of Slag**:
- The oxidized impurities combine with silica to form slag:
\[ \text{MnO} + \text{SiO}_2 \rightarrow \text{MnSiO}_3 \]
- This slag is removed from the top of the converter.

5. **Final Product**:
- The end product of this process is steel, which is a more refined and stronger material compared to pig iron.

6. **Conclusion**:
- Therefore, the Bessemer converter is primarily used for the production of steel from pig iron.
