The neutral (no-slip) point in the roll gap is where:

The surface velocities of the roll and the strip are equal

The maximum possible draft in rolling without slipping is governed by:

The coefficient of friction and the roll radius (\(\Delta h_{max}=\mu^2 R\))

Occurs above the recrystallization temperature, so the metal does not strain-harden permanently

Increase the contact arc length and the rolling force required
