The Answer is C.

Ref: RS Kurmi.

I also Agree @Nani.

The Correct answer is C.

Ref: Khurmi.

I too agree C is the correct answer.

I think C is the answer. Please find out the correct answer and update.

Answer is A. I agree with the given answer.

Correct Answer is C (hardening of rolls) refer RS Khurmi.

Yes, I too agree, C is the correct answer.

The correct answer is: camber on the rolls

Cambering the rolls involves giving them a slight convex shape, which helps to:

- Distribute the pressure evenly across the plate.
- Prevent the plate from becoming thinner at the edges.
- Achieve a uniform thickness across the plate.

Cambering is a common technique used in rolling processes to ensure uniform thickness and prevent edge thinning.

Here's why the other options are incorrect:

- Offset on the rolls (option 2) might cause uneven thickness and edge thinning.
- Hardening of the rolls (option 3) can improve their durability, but it doesn't directly affect the thickness uniformity.
- Antifriction bearings (option 4) reduce friction and wear on the rolls, but they don't impact the thickness uniformity of the plate.

Cambering the rolls is a critical aspect of rolling processes to achieve uniform thickness and high-quality plates.
