(vii) Roll Bending process: This type of Rolling process is used to bend the metal passed through it. The rollers are arranged that, when the metal is passed through it, gets a curvature along the roller's direction. The roll bending process is mainly used in bending tubes of chassis for the vehicle, which increases its aerodynamic efficiency.

Fig 4 Roll configurations in rolling mills. Two-high mill roll configuration – This is the most commonly used rolling mill configuration. In this configuration, there are two horizontally mounted rolls. The rolling mill motor drives either both rolls (top and bottom) or only one roll (normally the bottom roll) with the top roll rotating due to the friction between the roll and the …


Difficulties encountered may include roll deflection and sag, bearing induced effects, vibration, roll to wheel harmonics, wheel glazing, stainless steel loading and the like. Grinding, especially finish grinding, can be a sensitive process. One roll might grind with few problems. The next could take twice as long.
