Question

Match the steel plant related processes in Column I with the associated information in Column II.

• A. P – 1, Q – 4, R – 2, S – 3
• B. P – 1, Q – 4, R – 3, S – 2
• C. P – 2, Q – 4, R – 1, S – 3
• D. P – 2, Q – 3, R – 1, S – 4

Hint:

In steelmaking, processes like Corex and Midrex use gas-based reduction methods, while the Electric Arc Furnace is used for scrap steel melting. Continuous casting involves electromagnetic stirrers to control the solidification of molten steel.

Answer 1

The Correct Option is A

Let's analyze the processes and their corresponding information:

- P. Corex: The Corex process is a direct reduction method that uses a melter-gasifier to reduce iron ore. So, Corex is associated with 1. Melter-gasifier.

- Q. Electric Arc Furnace: The Electric Arc Furnace (EAF) is used for the production of steel by melting scrap steel. It is associated with 4. Hot heel, which refers to the molten metal left in the furnace after the process, used to assist in the next melt.

- R. Midrex: The Midrex process is a direct reduction process that uses natural gas as a reducing agent. Therefore, it is associated with 2. Natural gas reformer.

- S. Continuous Casting: The continuous casting process uses an electromagnetic stirrer to control the cooling and solidification of molten steel. So, it is associated with 3. Electromagnetic stirrer.

Thus, the correct matching is:

- P – 1: Corex with Melter-gasifier
- Q – 4: Electric Arc Furnace with Hot heel
- R – 2: Midrex with Natural gas reformer
- S – 3: Continuous Casting with Electromagnetic stirrer

Hence, Option A is the correct answer.
