The percentage of carbon in pig iron varies froma)0.1 to 1.2%b)1.5 to ...
The correct answer is option 'D': 4 to 4.5%.
Explanation:
Pig iron is the intermediate product obtained during the smelting of iron ore in a blast furnace. It is a brittle and high-carbon alloy that contains various impurities such as silicon, sulfur, phosphorus, and manganese.
The percentage of carbon in pig iron is an important factor as it determines the properties and quality of the final product. The carbon content affects the strength, hardness, and brittleness of the iron. It also influences its ability to be further processed into steel.
The percentage of carbon in pig iron typically ranges from 2 to 4.5%. However, the correct answer in this case is option 'D': 4 to 4.5%. This range is commonly found in pig iron produced in modern blast furnaces.
Importance of carbon content in pig iron:
1. Effect on strength and hardness: Carbon increases the strength and hardness of iron. Higher carbon content results in a harder and stronger material. This makes pig iron suitable for applications requiring high strength, such as in the production of castings and heavy machinery.
2. Effect on brittleness: Excessive carbon content can make pig iron brittle, reducing its toughness and impact resistance. This can lead to cracking and failure under load. Therefore, the carbon content needs to be carefully controlled to avoid excessive brittleness.
3. Influence on steel production: Pig iron is the primary raw material for steel production. By controlling the carbon content in pig iron, the desired carbon content in the final steel product can be achieved. This is done by adjusting the carbon content through the addition of other materials, such as scrap steel or ferroalloys, during the steelmaking process.
Conclusion:
The percentage of carbon in pig iron typically ranges from 2 to 4.5%. However, the correct answer in this case is option 'D': 4 to 4.5%. This range is commonly found in pig iron produced in modern blast furnaces. The carbon content plays a crucial role in determining the properties and quality of the final product, including its strength, hardness, and brittleness.
