In a single pass rolling process using 410 mm diameter

Home » Materials Science and Manufacturing Engineering » Materials Science and Manufacturing Engineering Miscellaneous » Question

In a single pass rolling process using 410 mm diameter steel rollers, a strip of width 140 mm and thickness 8 mm undergoes 10% reduction of thickness. The angle of bite in radians is

1. 0.006
2. 0.031
3. 0.062
4. 0.600

Correct Option: C

∆H = D(1 – cosα)

⇒ cosα = 1 -	∆H	= 1 -	0.1 × 8
	D		410

⇒ α = 3.57°

∴ α = 3.57 ×	π	= 0.062 radians
