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.

Camber angle is the measure in degrees of the difference between the wheels vertical alignment perpendicular to the surface. If a wheel is perfectly perpendicular to the surface, its camber would be 0 degrees. Camber is described as negative when the top of the tires begin to tilt inward towards the fender wells. Consequently, when the top of the tires begin to tilt away from the vehicle it is considered positive.

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

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

The correct Answer is C (Ref: Khurmi & Gupta).

Yes cambering is done for uniform thickness.

Answer is A. I agree with the given answer.

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

A is 100% right answer. I agree with it.

Cambering is done for uniform thickness.
