In the rolling process, roll separating force can be decreased by
Option (A)
reducing the roll diameter
Option (B)
increasing the roll diameter
providing back-up rolls
increasing the friction between the rolls’ and the metal
Correct Option:
Question Solution:
The various methods to reduce the separating are
1. Smaller roll diameter (which reduces the contact area)
2. Lower friction
3. Higher workpice temperature (even though friction will increase but p will be smaller
4. By applying the front tension and back tension
