    A main difference between Pig iron and steel is that steel has a lower level of...

    • Copper

    • Oxygen

    • Carbon

    • Aluminum

    Correct Answer
    A. Carbon
    Explanation
    Pig iron and steel are both iron alloys, but the main difference between them is the carbon content. Pig iron has a higher carbon content, typically around 3-4%, while steel has a lower carbon content, usually less than 2%. This difference in carbon levels affects the properties and characteristics of the materials. Steel with lower carbon content is stronger, more malleable, and has better weldability compared to pig iron. Therefore, the correct answer is carbon.

    The ingredient that makes stainless steel “stainless” is:

    • Zinc

    • Carbon

    • Aluminum

    • Chromium

    Correct Answer
    A. Chromium
    Explanation
    Chromium is the ingredient that makes stainless steel "stainless". It forms a protective layer on the surface of the steel, preventing it from rusting or corroding. This layer is composed of chromium oxide, which is highly resistant to oxidation and corrosion. Therefore, the presence of chromium in stainless steel enhances its durability and makes it suitable for various applications where resistance to corrosion is important.

    What does PCI stand for in a blast furnace operation?

    • Pulverized Coal Injection

    • Piped Coke Injection

    • Pulverized Coke Infusion

    • Piped Coal Infusion

    Correct Answer
    A. Pulverized Coal Injection
    Explanation
    PCI stands for Pulverized Coal Injection in a blast furnace operation. This process involves injecting pulverized coal into the blast furnace to replace some of the coke traditionally used as fuel. The pulverized coal is blown into the furnace through tuyeres, where it reacts with the hot air and helps in the reduction of iron ore to produce molten iron. PCI is a widely used technique in modern blast furnace operations as it allows for the reduction of coke consumption and improves the overall efficiency of the process.

    What is the melting point of low carbon steel?

    • 961°C (1762°F)

    • 1063°C (1946°F)

    • 1464°C (2700°F)

    • 3600°C (6512°F)

    Correct Answer
    A. 1464°C (2700°F)
    Explanation
    961°C = Silver. 1063°C = Gold. 3600°C = Carbon.
