In the basic Bessemer process for the manufacture of steel, the lining of the converter is made up of ____. The slag formed consists of ____.

Options

A. Steel
B. Wrought iron
C. Pig iron
D. Cast iron

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Bessemer Process**: The Bessemer process is a method for producing steel by blowing air through molten pig iron to oxidize impurities.

2. **Lining of the Converter**: In the basic Bessemer process, the lining of the converter is made up of quick lime, which is chemically represented as calcium oxide (CaO).

3. **Formation of Slag**: During the process, phosphorus present in the pig iron is oxidized. The phosphorus is converted into phosphorus pentoxide (P4O10).

4. **Reaction with Quick Lime**: The phosphorus pentoxide (P4O10) reacts with quick lime (CaO) to form calcium phosphate.

5. **Composition of Slag**: The slag formed in this reaction consists of calcium phosphate, which can be represented as Ca3(PO4)2. This type of slag is also known as Thomas slag.

6. **Final Answer**: Therefore, in the basic Bessemer process for the manufacture of steel, the lining of the converter is made up of quick lime (CaO), and the slag formed consists of calcium phosphate (Ca3(PO4)2).
